(At 4:32 p.m. EDT) NEW YORK ( TheStreet) -- Dow earnings have gotten the bulls running, but a mouse could spell trouble for the blue-chip average tomorrow. Disney ( DIS) reported fiscal third-quarter earnings of 52 cents a share, a penny better than Wall Street's consensus, according to Thomson Reuters, but down from a year earlier. Revenue slid 7% from a year ago to $8.6 billion, short of the $8.8 billion analysts expected. Not surprisingly, the House of Mouse said the latest quarter was impacted by weak advertising sales at its television stations. After a 1.3% rise Thursday, Disney shares dropped 2% in the after-hours session following the report's release. Earnings news most likely won't get better Friday. Chevron ( CVX) will become the last of five components of the Dow to report earnings this week, with analysts looking for a second-quarter profit of 95 cents a share on revenue of $33.41 billion, according to Thomson Reuters. That would be down from year-ago earnings of $2.90 a share on revenue of $82.99 billion. Of course, energy companies didn't have a good run in the last quarter as crude oil prices have plummeted. Take Exxon Mobil ( XOM), which Friday reported a 66% tumble in second-quarter profit. Earlier in the week, ConocoPhillips ( COP) reported an even worse 76% drop in profit during the recent quarter. Perhaps more concerning is a reversal of the action we've seen lately on the Dow. In the last few sessions, we've seen equities stage late-day rallies. Instead, we saw the Dow halve its gains in the last hour of trading Friday, finishing with a gain of 83.74 points. Earlier, the blue-chip average was higher by as many as 176 points.
