Consider a client who observes that an arbitrage-based mutual fund or a specific SIF investment strategy promises low-risk returns by exploiting price differentials between the cash and futures markets. They ask you why the realized return often falls slightly short of the theoretical price gap observed on the screen at 9:30 AM. As a distributor, your response must address the friction known as execution risk.
While the math of arbitrage seems perfect on paper, the practical reality of placing trades simultaneously in both the spot and derivatives segments involves timing delays and liquidity constraints that can erode the expected spread.
When a fund manager initiates a cash-future arbitrage, they must buy the underlying stock and sell the future contract at the exact same moment to lock in the profit. If the market is volatile, the ’leg’ in the cash market might execute at a slightly higher price than anticipated, or the futures order might be partially filled, leaving the position partially exposed to market risk.
These slippages are not anomalies; they are inherent costs that impact the net returns of the fund. For an investor, understanding that ‘risk-free’ often implies ’execution-managed’ is critical, as it changes their expectation from a guaranteed return to a managed, market-linked outcome.
Applying this to your advisory practice, always explain that these funds do not exist in a vacuum. A client investing ₹10 lakh in an SIF strategy expecting a set yield needs to understand that the manager’s ability to execute trades with minimal impact cost is a core competency. If the fund faces large, sudden inflows, the manager might struggle to deploy the capital without moving the stock prices against themselves.
This is why some funds close to subscriptions during periods of extreme volatility or market stress, as the managers prioritize protecting existing investors over gathering new assets.
Effective communication here prevents the client from feeling misled when the performance deviates from the theoretical spread. When you explain the mechanics of slippage and liquidity, you move from being a simple intermediary to a professional advisor who manages expectations with technical clarity. Remember that in the Indian market, where institutional and retail participants trade alongside, market impact is a real, tangible cost.
Your value lies in articulating how the manager navigates these hurdles to deliver the strategy’s stated objective, ensuring the client remains committed during inevitable periods of short-term variance.
