What Are Arbitrage Funds?

Introduction

Arbitrage funds are a category of mutual funds that aim to generate returns by exploiting price differences of the same asset across different markets.

In simple terms, these funds buy an asset in one market where it is cheaper and simultaneously sell it in another market where it is priced higher, earning the difference as profit.

Working of Arbitrage Fund

The strategy relies on market inefficiencies rather than predicting whether stock prices will rise or fall. Since the fund manager locks in the price difference at the time of the transaction, the risk is generally lower compared to equity funds. However, returns depend on the availability of arbitrage opportunities and market conditions.

In India, arbitrage funds are primarily classified as equity mutual funds because they invest a significant portion of their portfolio in equity and equity-related instruments.

This classification gives them a tax advantage compared to traditional debt funds.

How Do Arbitrage Funds Work in India?

The Indian stock market operates through multiple segments, mainly the cash market (where shares are bought and sold for immediate delivery) and the futures market (where contracts are made for buying or selling shares at a future date).

Sometimes, the same stock trades at different prices in these two markets. Arbitrage funds attempt to capture this difference.

Examples of Arbitrage Opportunities

Example 1: Reliance Industries

Suppose Reliance Industries shares are trading at:

• Cash market price: ₹2,800 per share
• One-month futures price: ₹2,830 per share

An arbitrage fund can buy the share in the cash market and simultaneously sell the futures contract at ₹2,830. When the futures contract expires, both prices usually converge. The fund earns approximately ₹30 per share, after adjusting for costs.

Example 2: Nifty Futures

Assume the Nifty 50 index is trading at:

• Spot Nifty: 22,000
• One-month futures: 22,120

An arbitrage fund buys Nifty ETFs or stocks representing the index and sells Nifty futures. The ₹120 difference represents the potential arbitrage spread.

Example 3: Merger or Corporate Events

During acquisitions or mergers, the target company’s stock may trade below the announced acquisition price due to uncertainty about deal completion.

For example, if Company A announces that it will acquire Company B at ₹500 per share, but Company B trades at ₹480, an arbitrage fund may buy Company B shares expecting the price to move closer to ₹500 when the deal completes.

Why Do Investors Consider Arbitrage Funds?

Arbitrage funds are often considered by investors looking for relatively stable returns with equity taxation benefits.

They can be useful for short-term parking of money, especially when equity markets are volatile.

Their key advantages include:

• Lower volatility compared to pure equity funds
• Potentially better post-tax returns than liquid funds for some investors
• Equity fund taxation: long-term capital gains after one year are taxed at 12.5% (as per current rules, subject to applicable exemptions)

However, arbitrage funds are not risk-free. Returns can fluctuate when arbitrage opportunities reduce, market volatility changes, or transaction costs increase.

Role of Arbitrage Funds in a Portfolio

Arbitrage funds can act as a middle ground between equity and debt investments. They are not designed for wealth creation like equity funds but can provide stability and tax efficiency for short-term and medium-term allocations.

For investors, understanding the fund strategy, expense ratio, historical spreads, and market conditions is important before investing.
