The S&P 500 stock index funds must buy AFTER stock is added to the S&P. They have up to 10 days to purchase shares of the new company. MM's will typically pick up shares for these index funds prior to the induction to some extent. They (MM's) will also manipulate the stock during the day to obtain shares at a more desirable price. Investors refusing to sell make it more difficult for this to happen. There is absolutely no reason to sell at this point. If John Hancock's earnings prove itself, anaylists will raise the target. Notice that JH hardly moves above 40 because it has already met its target. S&P induction will bring an increase in price though. Hold on to your shares.
