Friday afternoon there was a little extra trading toward the end of the day associated with the rebalancing. This trading was planned in advance and occurs on the last trading day of June as part of the annual rebalancing of the Russell Indexes. There appears to have been no extra volatility around the close on Friday despite a spike in volume around the close associated with the rebalancing of Russell Indexes. Electronic crossing volume on Friday came in at ten times the normal rate and everything went off smoothly. So tomorrow the Russell Indexes will be reported using the new components and portfolios that are constructed to replicate these indexes already have the correct members and relevant weightings.
