| Tiivistelmä: | This paper shows that S&P 500 stock betas are overstated and the non-S&P 500 stock betas are understated because of liquidity price effects caused by the S&P 500 trading strategies. The daily and weekly betas of stocks added to the S&P 500 index during 1985-1989 increase, on average, by 0.211 and 0.130. The difference between monthly betas of otherwise similar S&P 500 and non-S&P 500 stocks also equals 0.125 during this period. |
