Consider a HNI client in Mumbai who notices a temporary price discrepancy between the spot market and index futures. They propose a classic arbitrage trade, expecting a clean profit based on the mathematical spread between the two prices. As a distributor, your role is to remind them that the theoretical profit they calculate on a spreadsheet rarely matches the actual cash hitting their bank account.
The market is not a frictionless vacuum; every trade carries a silent weight in the form of transaction costs that can quickly erode a paper gain.
When calculating potential returns for sophisticated clients looking at arbitrage-based investment strategies, you must account for the full cost of execution. This includes brokerage fees, the Securities Transaction Tax (STT), exchange transaction charges, and clearing member fees. For high-frequency arbitrageurs, these costs are significant because they eat into the small margins available in a competitive market.
Even in the context of SIFs using arbitrage strategies, the manager must net these costs out before declaring the net asset value or returns to the investor. Failing to mention these costs to a client can lead to unrealistic expectations regarding fund performance or their own personal trading outcomes.
Consider an arbitrageur entering a trade with an expected spread of ₹10 per unit on a lot size of 50. If the total transaction costs—buy-side brokerage, sell-side brokerage, and associated levies—amount to ₹3 per unit, the net profit is not ₹10, but ₹7. If the client ignores these friction points, they might overestimate the efficacy of a strategy and blame the distributor when the final performance report shows a lower-than-calculated yield.
Transparency regarding these costs is not just a best practice; it is a vital part of the suitability conversation that protects your reputation.
Educated distributors ensure that clients view investment opportunities through a lens of net, not gross, returns. By integrating transaction costs into your initial explanations, you move from being a simple order taker to an advisor who manages expectations effectively. This depth of understanding is exactly what distinguishes a professional capable of managing complex portfolios from one who simply looks at market quotes.

An arbitrageur buys 100 shares in the cash market at ₹500 and sells a futures contract at ₹520. The total round-trip transaction cost (including STT, brokerage, and levies) is ₹5 per share. If the stock settles at ₹510 on expiration, what is the net profit per share?
Why must a distributor account for transaction costs when discussing arbitrage strategies with a client?
