Core Meaning
A skew index measures how option prices reflect demand for protection against unusual market moves.
Indian Market Context
Indian traders may study option skew in Nifty, Bank Nifty, and stock options to understand whether puts or calls are unusually expensive.
In real trading, the concept interacts with liquidity, bid-ask spread, order depth, brokerage, STT, GST, stamp duty, exchange charges, margin rules, and the reliability of the trading terminal. A clean textbook definition can become messy when the market is moving fast.
Example
If downside puts become much costlier than calls, the market may be pricing higher demand for protection.
Costs And Risks To Check
- Is the instrument liquid enough for the order size?
- What happens if the order is only partly filled or not filled at all?
- How much do brokerage, taxes, spread, and slippage change the result?
- Can leverage or margin calls force an exit at the wrong time?
- Is the trade allowed and properly routed through a registered broker?
Practical Takeaway
Skew is not a directional guarantee. It reflects option pricing and positioning.
Use trading concepts as tools, not as promises. A disciplined trader defines entry, exit, size, maximum loss, and review process before the order reaches NSE, BSE, or MCX.
