Using our robust historical database, we conduct extensive research on each underlying equity and determined which of those underlying equities’ options have historically had underpriced or overpriced options. 

Schaeffer's Volatility Scorecard (SVS) is a lagging indicator that measures a stock's realized volatility against the volatility expectations priced into that stock's options over the past year. The goal is to find which stocks have been the best -- and worst -- for premium buyers. The SVS is a very useful tool for premium sellers too, as “the worst” for a premium buyer can be construed as “the best” for a premium seller. Using our robust historical database, we conduct extensive research on each underlying equity and determined which of those underlying equities’ options have historically had underpriced or overpriced options. We rank each equity’s options relative to the others in our universe, with scores ranging from zero to 100. For more information on how to use these scores, please review instructions following the scorecard.
