A correct stock thesis can still fail through a poor option contract.

A stock may move in the expected direction while an option loses value. That can happen when the spread is too wide, implied volatility falls, the strike is poorly chosen, or there is not enough time for the thesis to develop.

Open interest, volume, bid-ask spread, and quote freshness affect whether a contract is reviewable. A modeled price can be useful for education, but it should not be confused with an executable quote.

When reviewing an option paper trade, record whether the stock thesis worked and whether the contract worked. If the thesis hit but the contract missed, the lesson may be about execution quality rather than market direction.
