We recently looked at the average analyst price targets for the stocks in the S&P 100 index. Below we highlight the ten most and least favored stocks in the index based on the difference between their current prices and their price targets. AES, MER and ATI currently have price targets that are more than 30% above current price levels. General Motors (GM) and Ford (F) lead the list of least favored stocks, which has been the case for the past couple of years. Remember, however, that although GM has been the least favored among analysts, it was also the best performer in the Dow 30 last year and is up nearly 20% this year as well.
