My problem with the stock market is that I fail to see who the incremental buyer will be to take the S&P 500 to 1,500. It?s not going to be the retail investor who has been hit with a 34% drop in home prices, two market crashes in the last decade, and a flash crash while their incomes are not keeping up with inflation. The last thing on their minds right now is to buy stocks,? said Doug Kass of hedge fund Seabreeze Partners.
