KBW Comments on S&P Index Rebalance, Occurring After the Close on Friday, 6/17

After the close on Friday, S&P announced constituent sharecount changes resulting from the 2Q11 rebalance, and all changes are effective after the close on Friday, 6/17, KBW reports.

“We estimate the impact of this quarter's share rebalance on the financial constituents of the S&P 500, 400 and 600 Indexes,” KBW writes. “We calculate the shares we expect will be needed to be purchased or sold by S&P index funds as a result of the rebalance and highlight financial constituents that we estimate should have a meaningful number of shares to be bought or sold by S&P index funds as a result of the changes.”
