How to research unusual options activity without treating it as a signal by itself.

Activity becomes more interesting when option volume is large compared with normal activity, the contract has enough liquidity to evaluate, the underlying stock has a catalyst, and the move is supported by price or news context. One contract print by itself is not a complete thesis.

Stock Analysis Desk treats unusual activity as a discovery input. It can move a ticker onto the research list, but the contract and stock thesis still need separate review.

Is the trade opening or closing? Is it near the bid, ask, or midpoint? Does the expiration make sense for the catalyst? Is open interest already high? Is the spread wide? Could the activity be part of a spread, hedge, or roll?

If those questions cannot be answered, the activity can still be logged as interesting, but it should not be treated as evidence of direction.

For paper review, record the contract, time observed, quote, stock price, catalyst, and why the activity looked unusual. Later, compare the contract movement with the original thesis instead of only checking whether the premium went up.
