David Kostin, Goldman Sach's U.S. equity strategist and his prediction of the S&P 500 at 1250 at the end of 2012. The S&P was at 1421 on April 1, 2012, the highest it has been since May 20, 2008. In his research note Kostin says that over the longer term the stock market will offer opportunities after a more normal growth environment is reestablished. This is similiar to the view held by John Bogle, founder of Vanguard. For the short term- the 2012-2013 time frame Kostin sees tactical risks, and results below average. The reason he gives is low economic growth and the large degree of uncertainty. The situation in Europe shows slowing to no growth and more deficit problems, and the sanctions on Iran pose risks for oil prices.
