Book excerpt: I present evidence that transactions of the stock futures of a flawed market index cause mispricing in individual stocks. In particular, I analyze whether stocks overweighted on the index are mispriced, especially when market movements driven by futures trading are observed. To detect such movements, I use a qualitative indicator based on daily stock market news and a quantitative indicator based on the intraday lead-lag relationship between the spot and futures markets. I find that overweighted stocks are overpriced (underpriced) when upward (downward) movements driven by futures trading are observed. By contrast, such mispricing is not observed for non-constituent stocks.
