Volworks “Contextual Expiration Returns™” and other period returns (monthly, quarterly, 1st half and 2nd half of year, annual returns, etc.) utilize a recency-biased weighting scheme by default for multi-year returns. We feel overweighting more recent returns makes sense. However, for investors who don’t want to adjust for recency for past returns, our platform also calculates the mean and median returns, along with standard deviation, for all our stocks and ETFs with no weighting adjustments. This is a platform setting that can be changed instantly by each user. By default, Volworks returns and proprietary analytics are based on the past 5 years of data. (Note: the Volworks Platform contains data from as far back as 1960, but for a host of reasons, our primary and default focus is on the past 5 years.)
