Category III AIF Investment Strategies – Long-Short | Market-Neutral | Arbitrage

Category III AIF investment strategies are the trading and arbitrage approaches a Category III Alternative Investment Fund uses to generate absolute returns, employing leverage, short positions and derivatives. They fall into three families. Equity-market strategies cover long-only, long-short, market-neutral, and directional and short-bias. Global-macro strategies take positions across currencies, fixed income, equities and commodities. Event-driven strategies cover activist, merger arbitrage and pre-IPO. Convertible arbitrage sits alongside these as a specialised long-short approach. Every strategy must be stated in the fund's Private Placement Memorandum, and leverage is capped at 2 times the NAV of the fund.

Check out NISM's Alternative Investment Fund Managers, the official NISM workbook for the Series XIX-C Certification Examination, published by Taxmann. The chapter on investment strategies runs eight of these approaches through a worked portfolio, with the actual positions, the derivative legs, the portfolio beta arithmetic and the analysis of what the manager got right or wrong. It sits within a 674-page treatment of the AIF industry across 17 chapters. The full range of NISM workbooks is on the NISM listing page.

1. What Sets Category III Apart

Category III AIFs are the only category permitted to use leverage, short positions and derivatives as a matter of investment policy rather than as a hedge of last resort. That permission is what makes the strategy question interesting.

A Category III AIF pools capital to invest over the long term, and it may take leverage, short positions and derivative positions to generate absolute returns for investors over the medium and long term. The phrase “absolute returns” carries weight. These funds are not trying to beat an index by two points; they are trying to make money whether the index rises or falls, and the strategies below are the different ways of attempting that.

What they are not is day-trading vehicles. Category III AIFs generally do not invest for the purpose of intra-day trading, though speculative positions in equities may be taken where the Investment Manager can identify short-term profit for the fund.

Whichever strategy the fund adopts, four things must be set out by the Investment Manager: the targeted sector for investment, the basis on which investments are selected, the time horizon, and the risk-return profile of the selected investments. These are disclosed to investors in the Private Placement Memorandum. By making a capital commitment, an investor indirectly consents to the stated strategy, which is why the PPM section on strategy repays careful reading before the cheque is written.

The corresponding strategies for the other two categories, which invest in unlisted companies rather than traded securities, are set out in Category I and II AIFs Investment Strategies.

2. Long-only Equity Strategy

The simplest of the equity-market strategies. The manager takes long, or buy, positions in selected stocks, with the aim of delivering absolute returns over the medium to long term and a strong emphasis on capital preservation.

Stock selection uses a top-down or bottom-up fundamental approach, looking for companies with predictable, scalable and quality business models. The manager works through historical data on dividend pay-outs, return on capital employed and other financial parameters to find them.

The interesting part is what a prudent manager does next. A long-only book carries the full market risk of every stock in it, so the manager may take a hedging position by taking the opposite position in a futures or options contract on the stock or index concerned. That means either a short position in a futures contract or buying a put option, with the underlying asset having similar characteristics to the reference asset in the portfolio.

In practice, index options are the more efficient instrument. A fund holding a spread of large-cap and mid-cap stocks can partially hedge its inherent market risk by buying a put option on a broad-based index such as NIFTY50 or S&P BSE SENSEX, and rolling the contracts forward as they approach expiry. Options tend to serve this purpose better than futures.

Two cautions follow. The hedging position, the type of contract and the index used all have to be revised regularly to keep replicating the characteristics of the portfolio underneath. And even with a hedge in place, a long-only strategy can be volatile and risky during economic downturns. A partial hedge is partial.

3. Long-Short Equity Strategy

Here the manager is not just picking good companies, but pricing them. The strategy identifies over-priced and under-priced stocks relative to the manager’s own fair valuation, which is arrived at through fundamental analysis together with macro-economic factors, industry-specific factors and government reforms.

The manager then has freedom to take a long position in the under-priced stocks and a short position in the over-priced ones. These funds are often described by their exposure ratio: a 130/30 fund takes 130 percent long positions and 30 percent short positions as a percentage of total investable funds, leaving net market exposure at 100 percent. A 120/20 fund works the same way with different numbers. The short leg is usually implemented through options and futures on the underlying assets rather than through borrowed stock.

The difference from a long-only strategy is timing as much as instrument. A long-short manager can take a short position in a stock at the time of the initial investment, not only later as a defensive move. That flexibility can create a natural hedge against the fund’s total market risk, but only where the long and short positions are in stocks sharing the same characteristics or sitting in the same industry.

Where they are not, the hedge does not hold. A fund that buys one mid-cap stock and shorts another mid-cap stock has not offset its exposure to the mid-cap segment; it has simply taken two separate bets, and the exposure can increase the total risk and volatility of the fund rather than reduce it.

Long-short strategies can be volatile and risky during economic downturns, and excessive leverage and short positions add to that volatility, which is why SEBI restricts the leverage such funds may take.

4. Market-Neutral Strategy

Market-neutral looks like long-short from a distance and is a different discipline up close.

It uses the same starting point, identifying over-priced and under-priced stocks against the manager’s fair valuation. The difference is the constraint: the fund maintains net zero or neutral exposure to a particular sector, industry or market capitalisation, by taking equal long and short exposures in equities. Because the fund is neutral to the broad-based index, industry or sector, its beta, its systematic risk, is zero or close to zero. Managers may use fundamental analysis or quantitative algorithms to decide which side of the trade a stock belongs on.

The distinction from long-short is worth stating plainly, because it is the point most often blurred. Market-neutral funds use long and short positions to minimise the systematic risk of the portfolio. Long-short funds use long and short positions to take advantage of undervalued and overvalued opportunities. Same instruments, different objectives.

The constraint costs the manager flexibility. Portfolio beta cannot drift significantly above or below zero, so the manager has limited freedom to trade across market capitalisations, industries or sectors as opportunities appear.

Portfolio beta is computed as the weighted average of stock-specific betas within each class of investments, with weights taken as each holding’s share of total investment in that class. Working an example through, a book holding three large-cap stocks with betas of 0.40, 2.00 and 1.20, where two equal long positions are offset by a single short position equal to the two of them combined, carries weights of 0.25, 0.25 and 0.50 and produces a weighted average beta of exactly zero for that segment. The individual stocks are anything but neutral; the combination is.

Which points to the residual risk. The individual stocks still carry unsystematic risk, unrelated to market risk. Their individual price movements change the portfolio mix, and the manager has to keep rebalancing to bring portfolio beta back to zero. It is a continuous operation, not a one-time construction.

Index derivatives add a second complication. A fund that buys a NIFTY50 call at one strike and a NIFTY50 put at a lower strike, in equal contract volume, has neutralised its index exposure above the higher strike and below the lower one, but remains exposed in the band between the two strikes. Because the strikes differ, portfolio beta is not exactly zero. In practice, beta will not remain exactly zero for a market-neutral fund, and where the deviation arises from options taken to hedge market risk, a beta close to zero is a justified outcome rather than a failure of the strategy.

A zero beta does not mean the strategy is safe. Excessive leverage and concentrated stock positions increase volatility regardless of what the beta figure says.

5. Directional and Short-bias Strategies

A directional strategy is the opposite of market-neutral. The manager takes a view on where the overall market is going, over the short term or the medium to long term, and positions the fund net long or net short in selected stocks or a broad-based index accordingly. There is no attempt to hold beta near zero. If the fund is net long, it benefits from an upward move, and the reverse.

Short-bias is a type of directional strategy. The manager takes both long and short positions in selected stocks or a broad index, but maintains net short exposure to the broad market, so the fund benefits from a downward move.

The related strategies separate on net exposure, which is the cleanest way to hold them apart:

Strategy	Net exposure to the market
Long-only	Net long; positions are buy positions, with hedges taken defensively
Dedicated-long	Net long; the manager takes long positions exclusively
Long-short (130/30)	Net long or net short; in the typical 130/30 formulation the manager maintains a net long position of up to 100 percent of total investable funds
Market-neutral	Net zero, with portfolio beta at or close to zero
Short-bias	Net short to the broad market at all times

Reading a fund’s positions against this table is how the strategy is identified in practice. A fund holding net short positions in both large-cap and mid-cap stocks is running short-bias. A fund that has bought large-cap shares outright and holds call options on NIFTY50 for a later expiry is running a dedicated-long directional strategy, since it profits if the index rises.

Both directional and short-bias strategies can be volatile and risky during major macro-economic upturns as well as downturns, depending on the net exposure the manager has taken. The risk is symmetrical, and it is deliberate.

6. Global-Macro Strategy

Global-macro breaks out of the equity market entirely. A Category III AIF pursuing this strategy takes long and short positions across asset classes: currencies, fixed income securities, equities, commodities, real assets and interest rate derivatives, across multiple markets and geographies.

Selection is driven by macro-economic trends and factors rather than fundamental analysis of each company’s historical data. Larger players in the Category III market run advanced algorithms to analyse macro-economic trends across multiple dimensions, combining quantitative and discretionary inputs.

Global-macro is a framework more than a single technique. Within it, the manager may apply a long-only, market-neutral, directional or long-short approach in each market. A manager might take long positions in Indian corporate debt securities, short positions in the Euro, long positions in U.S. Treasury bills, and stay market-neutral in crude, all at the same time and subject to the regulatory guidelines applicable from time to time.

That is also how a global-macro fund is identified from its holdings. A fund holding Indian large-cap and mid-cap equity long, short currency futures in USDINR and GBPINR, and long WTI crude oil futures is pursuing a global-macro strategy on the basis of the spread of asset classes. If its net exposure is long, the approach within that framework is long-short. The diversification across asset classes is the point: it is what allows the fund to manage the total risk of the portfolio.

7. Convertible Arbitrage Strategy

Convertible arbitrage is a type of long-short strategy aimed at the mispricing of a company’s convertible securities against its equity.

A convertible security is a hybrid instrument, a convertible debenture or convertible preference share, that gives the holder the option to convert into equity shares at a pre-determined date and conversion ratio. The holder can keep collecting coupons or convert, whichever is worth more.

The trade is to take a long position in the convertible security issued by a company and simultaneously take a short position in the same company’s equity shares. The intent is a profit largely independent of which way the share price moves. If the share price falls, the fund gains on the short leg while continuing to earn coupons on the convertible. If the share price rises, the fund converts and sells the resulting equity at market value, which compensates for the loss on the short position.

The opportunity exists because a company’s convertible bonds are sometimes priced inefficiently relative to its equity shares, and the pricing is determined by the conversion ratio inherent in the security. The fund attempts to profit from those pricing errors.

The economics are worth setting out, because the headline gain is not the return. Running a representative position, a fund that invests INR 1 crore in a 12 percent convertible bond, funding 20 percent from its own capital and 80 percent from borrowing at 10 percent, and shorting 50,000 equity shares against it, faces four running items before any exit: borrowing cost on the leveraged portion, coupon income on the bond, borrowing fees payable to borrow the shares for the short leg, and dividends foregone on those shorted shares, since a short seller does not receive the dividend. The exit adds two more: profit on conversion of the bonds, and the loss on squaring off the short position when the share price has risen.

Netted against a fund contribution of INR 20 lakh, that structure can produce a return on investment of 27.50 percent over a year. The leverage is doing much of that work, and so is the coupon, which is an additional near risk-free income stream for the fund. Had the share price fallen instead, the fund would not convert. It would square off the short position instead, for a net gain the workbook puts at 15 percent without working the figures through.

Both outcomes are positive in that illustration, which is the appeal. The caution is that convertible arbitrage is difficult to implement and can be riskier at times of changing macro-economic factors and unpredictable events. Market factors, economic cycles and company fundamentals all bear on whether the arbitrage closes as intended.

8. Event-driven Strategies

Event-driven strategies take positions in the equities or derivatives of a single target company, triggered by a significant corporate event at that company: debt restructuring, mergers, acquisitions, spin-offs, or a change in management. The event moves the price of the company’s equity or fixed income securities, and the fund positions ahead of or around that move. Unlike a pure equity-market strategy, an event-driven strategy may take long and short positions in equities or fixed income securities. The material corporate event is the primary indicator.

8.1 Activist Strategy

An activist fund makes a significant investment in an investee company and sets out to benefit from a material corporate event there. Events such as a change in management team, a bankruptcy filing or the shutting down of a business segment can push the equity price down sharply. Where the manager judges that the fund can improve the operational efficiency of the company, it commits significant capital, enough to let the fund participate in the management process of the investee company.

Activist funds take a private equity approach with a long-term orientation, which is unusual for Category III. The strategy is also referred to as a special situations strategy, since a fund may look to take or increase a stake in a company undergoing NCLT proceedings that is likely to be acquired by a larger player in the same industry.

SEBI’s stewardship code sits behind this. All Alternative Investment Funds are required to actively monitor their investee companies and vote on important company matters, and to maintain a clear policy for collaborating with other institutional investors to preserve the interests of ultimate investors.

The constraint is concentration. Activist funds run less diversified portfolios with illiquid investments, and SEBI limits a Category III AIF to not more than 10 percent of its investable funds or its NAV in a single investee company. A large value fund for accredited investors gets 20 percent instead. Given those ceilings, Indian Category III funds are typically able to take activist positions only in small-cap or mid-cap companies, which carry high failure risk precisely when the manager is attempting a turnaround. Large value funds, where each investor is accredited and commits not less than INR 70 crore, are the most suitable vehicle for the strategy, which remains at a nascent stage of development in India.

8.2 Merger Arbitrage Strategy

Merger arbitrage seeks a profit from the acquisition of a target company by an acquiring company. The fund takes a long position in the target’s equity and simultaneously takes a short or long position in the acquirer’s equity.

The long leg in the target is straightforward. An acquirer must typically pay a premium over the target’s unaffected share price, the price before the deal, because the target’s board will only approve an acquisition priced significantly above the current market. The fund is capitalising on the spread between the target’s current price and the acquisition price once the deal completes.

The acquirer leg is where judgement enters, and the direction of the position is not fixed. A short position in the acquirer is taken for two reasons. The first is deal-completion risk: until final allotment of shares, the deal may fail to secure board, regulatory or shareholder approval, or may be delayed, and either raises the risk of failure. The second is the premium itself. If the premium paid to the target is over-valued, the acquirer’s share price is likely to fall; if it is under-valued, the acquirer’s price is more likely to rise. The valuation method used to arrive at the target’s fair market value drives the conversion ratio, and it is the conversion ratio that creates the arbitrage.

Which means the acquirer can be the long leg where the analysis supports it. Where the merger has already been approved by both boards and by the regulators, deal-failure risk is minimal, and the fund should ideally take a long position in the acquirer as well. The test is the conversion ratio: divide it out against the target’s pre-announcement price and compare the result with the acquirer’s market price. Where a conversion ratio of 139:10 against a target trading at INR 39.25 implies a fair price of INR 545.58 for an acquirer trading at INR 540.00, the acquirer is under-valued on the terms of the deal itself and should be bought. A fund taking both legs long in that situation, within minutes of the announcement, produced a return of 4.86 percent in a single day in the worked case in the NISM workbook.

The strategy still depends on the manager estimating the fair value of the premium correctly, and remains exposed to changing macro-economic factors and unpredictable events at the companies involved.

8.3 Pre-IPO Strategy

Pre-IPO shares are shares with unique identification numbers issued to employees or institutional investors, including Category III AIFs, before the shares are offered to the general public in an IPO. They are offered to institutional investors at a discount to the IPO issue price, in recognition of the size of the investment and the risk taken. The allotment of those shares to selected institutional investors just before the IPO date is the pre-IPO placement.

A fund pursuing this strategy holds a mandate to subscribe to pre-IPO shares at a discount to the eventual issue price. A fund buying at INR 120 per share ahead of an IPO priced at INR 130 has taken a discount of INR 10 per share, or 7.70 percent off the issue price.

The discount is not free money. Under the SEBI (Issue of Capital and Disclosure Requirements) Regulations, 2018, institutional investors including AIFs that subscribe to pre-IPO shares or to a Qualified Institutions Placement are subject to a lock-in period running from the date those shares are listed through the IPO. The fund holds an illiquid position for that period regardless of where the price goes after listing, and the entry discount is the compensation for accepting it.

9. The Limits Every Strategy Operates Within

Whichever of these strategies a Category III AIF runs, three regulatory constraints apply to all of them.

Leverage. A Category III AIF may take leverage through derivative contracts only with the prior consent of investors, up to a maximum of 2 times the NAV of the fund, and with periodic disclosures to investors and to SEBI. Leverage is computed as total exposure, being long positions plus short positions after permitted offsetting, divided by NAV. Idle cash and cash equivalents are excluded from exposure, as are temporary borrowing arrangements fully covered by capital commitments from investors. Offsetting is allowed in accordance with SEBI’s norms for hedging and portfolio rebalancing. A Category III AIF investing in units of other AIFs may take leverage not exceeding 2 times the NAV, excluding the value of its investment in those units.¹

Exposure measurement. On the day a futures contract is entered into, exposure is the futures price multiplied by the number of contracts; on subsequent valuation days it is marked to market. For options, exposure on day one is the premium paid, and thereafter the position is priced using the Black-Scholes model and marked to market. Long and short positions in the same stock, index or commodity with the same maturity may be offset against each other in computing net exposure. Margins deposited with brokers and the central counter-party are treated as an asset for NAV purposes.

Concentration. A Category III AIF may invest up to 10 percent of its investable funds in one investee company, directly or through units of other AIFs. For a large value fund for accredited investors, the limit is 20 percent. For investments in listed equity, the 10 percent and 20 percent limits may be computed against either investable funds or the NAV of the scheme.

These three constraints are why a strategy that works in an unconstrained global fund may not transfer intact to an Indian Category III AIF, and why the strategy section of a PPM should always be read against them.

10. Frequently Asked Questions

10.1 What investment strategies can a Category III AIF use?

Equity-market strategies, being long-only, long-short, market-neutral, and directional and short-bias; global-macro strategies across currencies, fixed income, equities, commodities, real assets and interest rate derivatives; convertible arbitrage; and event-driven strategies, being activist, merger arbitrage and pre-IPO. The strategy the fund follows must be disclosed in its Private Placement Memorandum.

10.2 What is the difference between a long-short and a market-neutral strategy?

Both take long positions in under-priced stocks and short positions in over-priced ones. A long-short fund does so to profit from the mispricing and may end up net long or net short. A market-neutral fund does so to eliminate systematic risk, holding equal long and short exposures so that portfolio beta stays at or close to zero.

10.3 How much leverage can a Category III AIF take?

Up to 2 times the NAV of the fund, computed as long plus short positions after permitted offsetting divided by NAV. It requires the prior consent of investors and periodic disclosure to investors and to SEBI.

10.4 What is a 130/30 fund?

A long-short equity fund in which the manager takes long positions equal to 130 percent of total investable funds and short positions equal to 30 percent, leaving net market exposure at 100 percent. A 120/20 fund follows the same construction with different proportions.

10.5 How does convertible arbitrage make money?

By taking a long position in a company’s convertible security and a short position in its equity shares, so that a fall in the share price is offset by the short leg while coupons continue to accrue, and a rise in the share price is captured by converting and selling the resulting equity. The opportunity comes from the convertible being mispriced relative to the equity under its conversion ratio.

10.6 Can a Category III AIF run an activist strategy in India?

Yes, but the concentration limits shape it. A Category III AIF may not invest more than 10 percent of its investable funds or NAV in a single investee company, rising to 20 percent for a large value fund for accredited investors. This generally confines activist positions to small-cap and mid-cap companies, and large value funds are the most suitable vehicle for the strategy.

10.7 Are pre-IPO shares bought by an AIF locked in?

Yes. Under the SEBI (ICDR) Regulations, 2018, institutional investors including AIFs subscribing to pre-IPO shares or a Qualified Institutions Placement are subject to a lock-in period from the date the shares are listed pursuant to the IPO.
