The Dow Jones Industrial Average on Monday was set to rise slightly , with shares of Exxon Mobil Corp., and Chevron Corp., turning higher even as Wall Street looked to contend with the fallout of Hurricane Harvey. Shares of Exxon Mobil and Chevron were set to inch up at the open, with the Dow components faring relatively well even as the now-Tropical storm has left some 50 inches of rainfall and flooded large swaths of energy-rich Houston area over the weekend. Exxon closed its Baytown refinery, located on the Houston Ship Channel–the second-largest refinery in the country, processing as much as 560,000 barrels. Separately, energy-related industrials giant, Caterpillar Inc. , was slightly higher. Popular energy-focused exchange-traded funds, SPDR Energy Select Sector and United States Oil Fund LP , however, were trading lower in premarket action. U.S. traded crude-oil futures were off 0.5% at $47.42 a barrel. Overall, the stock market looked set to open higher, with futures for the S&P 500 , the technology-heavy Nasdaq-100 and the Dow all up at least 0.1%.
