Russell Investments recently posted a list of companies joining and leaving the Russell 3000 index on June 25. In anticipation of this event, many investors have either bought the stocks of companies being added to the index or sold those being deleted from it. Big mistake.
In fact, it might be better to do the exact opposite, because stocks deleted from an index tend to have significantly higher factor-adjusted returns than index additions, and stocks added to an index have "poor long-term returns," according to a study published in the Financial Analysts Journal in 2008 by Jie Cai, an assistant professor of finance at Drexel University, and Todd Houge, a chartered financial analyst and professor of finance at the University of Iowa.
1. Don't sell stocks deleted from an index, or buy stocks added to an index
The Russell 3000 index represents about 98% of the investable U.S. equity universe, and on June 25 about 261 companies will be added to the index and about 205 companies will be deleted from it.
That fact alone shouldn't prompt investors to make buy or sell decisions, said David Zuckerman, a certified investment management analyst and chief investment officer of Zuckerman Capital Management LLC. (more)
