Arbitrage

Investments

Arbitrage is simultaneously buying and selling the same asset in different markets to profit from price differences. Arbitrage mutual funds exploit the price difference between the cash market (NSE/BSE spot prices) and futures market. They are taxed like equity funds but carry very low risk.

Difference Rs 20/share is locked-in profitn4. At futures expiry: position closes, Rs 20 profit realisedn5. Roll: simultaneously open May futures position for next month's arbitragennReturns: typically repo rate equivalent (6.5-7.5%), with low volatility. Taxed as equity (STCG 20% if sold within 1 year, LTCG 12.5% after 1 year). Better than liquid funds for investors in 30% bracket holding for 12+ months.

Real-life example

🇮🇳 India example

Priya is in 30% tax bracket. She has Rs 5L for 15 months. Options: Liquid fund (7.2%, taxed at 30% = 5.04% net) vs Arbitrage fund (7.0%, STCG if sold before 12 months, LTCG 12.5% after 12 months = 6.125% net). Arbitrage fund nets Rs 11,000 more for 15-month holding due to equity tax treatment.
