Monthly Returns-showing Sept before market opens?

Why would the stat matrix already be showing returns for September prior to market open for that month?

On MFS-Cyclical Model it shows September results at 7:00am est hour prior to market open for the month

Is this in anticipation of what is to happen?

Why would this be??

Thank you


We take snapshots of each system at intervals. The monthly stats you see are based on the change in equity between two snapshots. The implication is that snapshot 1 was take sometime before the market close on August 31 and snapshot 2 was taken on Sep 1 (but before the market opens). In other words, the September results may include a few hours of August.
