I have not verified the figures, but I am a big fan of Rob Arnott and Research Affilaities:

Research Affiliates has analyzed historical data from 1989 to 2017. The results show a clear pattern for stocks that are included in a cap-weighted index (such as the MSCI USA or S&P 500):

1. the pre-inclusion phase ("the hype")
Stocks are usually included when they have already experienced an enormous rally.

Performance jump: In the period between the announcement and the actual implementation (the "effective date"), these shares rise by an average of +5.23% (523 basis points) compared to the market as a whole.

The last day: Over a third of this increase often happens on the very last day before inclusion, when the large ETFs are forced to buy the stock at any price to track the index.

2. the post-inclusion phase (the "reversal")
Once the index funds have completed their purchases, the artificial buying pressure often dries up.

12 months later: In the year after inclusion, these "newcomers" underperform the market by -1.28% on average.

Comparison with index leavers: It is particularly exciting that the stocks that are kicked out of the index (often the "ugly ducklings") outperform the market by over 20% in the year following their ejection.
