How to read CMCSA unusual options activity

Each row is a single CMCSA options trade where same-day volume was large relative to open interest and the premium was large. Bullish means calls were bought at or above the ask; bearish means puts were bought at or above the ask. Volume above open interest suggests, but does not prove, that new positions were opened. Check whether CMCSA open interest rose the next day to confirm. Learn more in our guide to unusual options activity and volume vs. open interest.
