Methodology#

Each September is the return from the last close of the month before to the last close of September, from SPY's closes since 1994: total return over its dividend-adjusted closes, price return over its split-adjusted closes. The month in progress is as of the last close and moves with the tape during the session; it is shown beside the record and never averaged into it. Past performance does not predict future returns; not investment advice.
