My Arbitrage Fund Return is Very Low This Month — What is Happening?

You opened your statement this month and your arbitrage fund — the one that was supposed to be the safest equity product in the market — barely beat your bank savings account. The 1-year chart still shows 6 to 7 percent, but the past 30 days were almost flat. Before you switch out in a hurry, take a moment to understand what is hybrid fund behaviour during low-spread phases, because the answer almost never involves anything broken in the product.

This guide walks through the real reason your arbitrage fund had a weak month, what to expect over the next quarter, and how to use the category sensibly instead of dropping it on impulse.

The Pain: A "Safe" Fund Earned Almost Zero

Arbitrage funds are sold as the safe corner of the hybrid fund universe. The pitch goes like this:

• Buy a stock in the cash market.
• Simultaneously sell the same stock in the futures market.
• Pocket the small price difference, also called the arbitrage spread.

When done thousands of times across hundreds of stocks, the manager earns a steady return with very little market risk. Steady, however, is not the same as constant. In some months the spread shrinks to almost nothing.

The Diagnosis: Arbitrage Spreads Are a Market Variable

The arbitrage spread is not a fixed coupon. It is the rate at which traders are willing to fund a long-short position. That funding rate depends on three things:

• Short-term interest rates. Lower rates compress arbitrage spreads. When the Reserve Bank holds rates steady or cuts them, your fund's gross return drops too.
• Demand from cash-future traders. Heavy rollover months tend to widen spreads. Quiet months tighten them.
• Market volatility. Low realised volatility kills the spread. Most participants stay on the sidelines and the manager has less to scoop.

This month likely combined two or three of these factors. Your fund is doing the same job — there was simply less to be done.

Why Arbitrage Funds Slow Down in Some Months

Three patterns explain almost every weak month:

• Expiry-week distortions. Most arbitrage trades unwind on the monthly F&O expiry day. The two trading days before and after expiry can be flat by design.
• Holiday-shortened months. A month with multiple trading holidays gives the manager fewer days to capture spreads.
• Index inclusion or exclusion events. Lumpy events can pull liquidity away from regular spread trades for several days.

None of these mean the fund has changed strategy. They simply mean the operating environment changed for a few weeks.

What Hybrid Fund Categories Get Lumped Together and Confuse Investors

SEBI defines six hybrid fund categories. Investors often confuse them, then judge an arbitrage fund by the wrong benchmark.

• Arbitrage funds: minimum 65 percent equity-derivative pair trades. Lowest risk in the hybrid pool.
• Equity savings funds: mix of arbitrage, direct equity, and debt. Higher return potential, higher volatility.
• Conservative hybrid funds: 10 to 25 percent equity, rest in debt. Closer to a debt fund in feel.
• Balanced hybrid funds: roughly equal equity and debt allocation.
• Aggressive hybrid funds: 65 to 80 percent equity, rest debt. Behave like equity funds in a bad market.
• Multi-asset funds: hold equity, debt, and gold or commodities.

If your statement looks weak this month, the first question is which exact category you own. An aggressive hybrid fund in a bear month behaves nothing like an arbitrage fund in a quiet spread month, even though both wear the hybrid label. The official scheme list with categories sits with AMFI.

The Fix: Set Realistic Expectations and Use Tax Wisely

Once you accept that arbitrage spreads vary, the right next step is to set expectations and tax planning around the average, not the best month.

• Plan for 5 to 6 percent annualised in normal years. Some months will print 8 percent annualised, others 2 percent. The average is what matters.
• Use the equity tax treatment. Arbitrage funds are taxed as equity funds. Short-term gains within a year attract a lower rate than debt funds. Long-term gains above 1 lakh per year attract a flat 10 percent.
• Park money you need in 3 to 12 months. The category beats a savings account on tax-adjusted return, even with the occasional flat month.

How to Prevent the Next Disappointment

Three habits keep the relationship with arbitrage funds healthy:

• Review on a 12-month basis, not monthly. The category is a low-spread machine; judging it by 30 days is like judging a marathon runner on a single kilometre.
• Diversify across two or three funds. Each AMC has slightly different trade-execution strengths. Two funds smooth out manager-specific weak months.
• Match to the right goal. Use arbitrage funds for parking, not for compounding. For a 5-year goal, an equity fund or equity savings fund is usually better.

The Take-Away

A weak month from your arbitrage fund is rarely a bug. It is the category showing its true colours during a thin spread phase. Read the AMFI category, know the average expected return, lean on the equity tax break, and let the next four quarters do the talking. Most investors who panic-switch end up paying the worst possible tax exit at the worst possible time.
