What is high IV in covered calls?

High IV (implied volatility) means the market is pricing in larger expected price moves, which inflates option premiums. For covered call sellers, high IV is favorable — it means you collect more premium for the same strike and DTE.

What IV percentile is good for covered calls?

IV percentile above 50 is generally favorable for selling premium. Above 70 is considered high — the optimal window where premiums are rich but the underlying's move expectation hasn't become extreme.

Should I only sell covered calls when IV is high?

Ideally yes. The risk/reward of selling covered calls improves significantly when IV is elevated. In low-IV environments, premiums may not adequately compensate for the risk of capping your upside.

How is IV percentile calculated?

IV percentile = (days IV was below current IV in past 52 weeks) / (total trading days). A reading of 70 means current IV is higher than 70% of all daily IV readings in the past year.

What causes high IV in stocks?

Upcoming earnings, FDA decisions, macro events, sector news, and general market volatility. The most consistently high-IV names are tech, biotech, and leveraged ETFs.

Why High IV is the Best Time to Sell Covered Calls

Implied volatility is the key input that determines option premium. When IV is high (above the 70th percentile of its 52-week range), you're collecting premium at the richest possible level — the market is paying you maximum price for the risk you're taking. When IV is low, the same strike and DTE generates far less income. This is why tracking IV percentile matters more than tracking the absolute IV number: a 40% IV might be high for a utility stock but low for a semiconductor name. Our screener normalizes this by filtering on percentile, showing you which stocks offer the best premium relative to their own historical baseline.
