The Dow rose nearly 2 percent, while the S&P 500 was up 1.5 percent. All 10 major S&P sectors were higher, led by the 3.64 percent rise in the energy sector . Investors are still reeling from a turbulent start to 2016, which saw Wall Street post its worst-ever start to a year, and a two-day recovery late last week was largely wiped out on Monday.
