For Investors Only -- CVX and XOM Up Today -- US Oil Supplies Drop

Link here.

Exxon Corp. and Chevron Corp. moved up Wednesday after data showed a big drop in U.S. crude oil supplies, while oil-service shares reversed course and rose in volatile trading.

Exxon Mobil rose 1.3% and Chevron advanced 1.7%. The two oil majors ranked among the top gainers in the 30-stock Dow Jones Industrial Average, which rose about 4 points after spending much of the session in the red. 

Not a small drop, not a mediocre drop, but a "big" drop.
