This Friday on the market close, Russell will fully reconstruct its U.S. Index series. This means the Russell 2000, The Russell 1000 and the Russell Multiple Shares Class indexes will all see very heavy trading volume. In fact, the Credit Suisse analytical team estimates a gigantic $54 billion in two-way trading to hit the tape on the close.

The reconstitution accounts for additions and deletions to all the indexes and also reweighting within the indexes. In an odd twist, sometimes the stocks deleted from the Russell 2000 outperform a basket of companies that are added to the index. It is the reverse in the Russell 1000, as the additions to the index outperform the deletions.

We screened the Credit Suisse research for the five top additions to the Russell 1000 this year. While the stocks that are going to be added are well known in advance, and people do tend to front-run the buys, there will still be a ton of action on the close Friday.

Delphi Automotive PLC (NYSE: DLPH) is a leader in the automotive original equipment manufacturing segment and will be added to the Russell 1000. The Credit Suisse team estimates that a total of 9.455 million shares will be bought at an estimated value of a gigantic $828 million. That is a massive 465% increase in the average 10-day trading volume. Delphi shares closed Tuesday at $88.54.
