Leverage: What It Does and Does Not Change
Leverage means controlling a position larger than the capital posted against it. In derivatives it arises because margin is a fraction of contract value rather than the full amount.
How to read it
- Leverage is a ratio of exposure to capital. Controlling ₹14 lakh of contract value with ₹1.2 lakh of margin is roughly 12 times leverage.
- It scales outcomes in both directions identically. There is no asymmetry in the arithmetic — a 1% adverse move costs the same proportion it would have gained.
- It changes the capital required to hold a position. It does not change the distance to your stop or the loss that stop implies.
What it does not tell you
- Leverage is routinely described as a tool for amplifying returns. It amplifies the outcome, whatever that turns out to be, and the losing case is where accounts end.
- Because losses and recoveries are asymmetric — a 50% drawdown needs a 100% gain to undo — magnified losses are harder to reverse than magnified gains are to repeat.
- Available leverage tells you what a broker permits, which is unrelated to what your risk limit allows.
Frequently asked questions
How does leverage work in F&O?
Margin is a fraction of contract value, so a smaller amount of capital carries a larger exposure. The profit and loss moves against the contract value, not against the margin.
Is high leverage bad?
Leverage is arithmetic and is neither good nor bad in itself. What matters is position size relative to a stop-loss. High available leverage becomes a problem when it is used to determine size instead of the risk calculation.
Does leverage increase my risk?
Using leverage to take a larger position increases the loss a given adverse move produces. Leverage alone, with position size unchanged, does not — which is precisely why sizing should be derived from the stop rather than from available margin.
What leverage do Indian brokers offer on F&O?
It is determined by exchange margin requirements rather than broker preference, and requirements vary by instrument and volatility. Intraday leverage in particular is subject to regulatory rules that have changed over recent years.
