U.S. government is again shutdown after 17 years, making 800000 federal employees idle. I read on Bloomberg that historically S&P has risen around 11 percent after the government shutdown with an average return of 9 percent over 12 months. Stocks went down on the uncertainty whether government will shut down or not. Is it a good time for investors to long? As there will be volatility in the market and it is going to affect the economy, might be a good time to trade on indexes.
