Daily benchmark tracking the average annualized covered call yield across 4,000+ scanned symbols. Updated every evening post-market close.
The CCII tracks the daily average annualized yield across all covered call candidates passing our liquidity filters (open interest ≥ 100, bid-ask spread ≤ 5%). A rising index signals expanding implied volatility — more premium available for sellers. A falling index means IV compression — tighter premiums across the board.
Read Methodology →Use the CCII as a market context gauge before entering covered calls. When the index is above its 90-day average, option premiums are elevated — a favorable environment for income sellers. When it drops significantly below average, consider tightening position sizing or waiting for IV to recover.

The CCII tracks the daily average annualized yield across all covered call candidates identified by our scanner. Today's reading is 17.3%. It serves as a benchmark for the overall income environment for covered call sellers.
The index updates once per day after market close — typically available by 7:30 PM ET. Each data point represents the post-close scan results for that trading day.
CCII = average annualized_return across all candidates passing our liquidity filters (OI ≥ 100, bid-ask spread ≤ 5%). The formula for each candidate is (bid / stock_price) × (365 / DTE). See the methodology page for details.
A high CCII reflects elevated implied volatility across the market — which means higher premiums. However, high IV often precedes increased volatility. Use the index as a context gauge, not a directional signal.
