[Morgan Stanley Strategist: Iran Situation Unlikely to Shake Bullish View on U.S. Stocks] Morgan Stanley strategists believe that unless oil prices surge significantly and sustainably, the outbreak of conflicts in Iran and the Middle East is unlikely to shake their bullish outlook on U.S. stocks. The team led by Mike Wilson wrote in a report that, based on historical experience, geopolitical risk events have not caused lasting volatility in the U.S. stock market. They cited the average performance of the S&P 500 index in the months following similar events as evidence. 'Unless oil prices experience a historic and substantial rise and remain at high levels, recent events are unlikely to alter our bullish expectations for U.S. stocks over the next 6 to 12 months,' they wrote.
