Investors should buy put options on the Standard & Poorâs 500 Index because the benchmark for U.S. stocks may fall back to the 11-year low it reached in November, Goldman Sachs Group Inc. said. âDismalâ fourth-quarter profits and forecasts from companies as well as waning investor confidence in President Barack Obamaâs economic stimulus plan may drive the S&P 500 toward 752.44 in the next month, Goldman strategists said. For investors using a âput spreadâ strategy, the highest payoff would be generated through buying March 825 puts and selling March 745 puts, Krag âBuzzâ Gregory and John Marshall wrote in a report distributed to clients today. That trade would produce $1.85 in profit for every $1 invested should the S&P 500 drop to its November low, they said. The index declined 0.1 percent to 824.94 at 1:14 p.m. in New York today. http://www.bloomberg.com/apps/news?pid=20601087&sid=aotLF3OO7sDQ&refer=home And sell Goldman puts strike 100.
