In what has become a common occurrence, the stock market is once again flirting with all-time record highs, with the Dow Jones Industrials (DJINDICES:^DJI) up 42 points as of 10:55 a.m. EDT. Yet what's surprising about the rise is that it comes on the heels of some economic news that points to cracks in the bull market's armor. Today's reading of the Case-Shiller home price index showed gains of just 1% in May after seasonal adjustment, falling short of expectations. Consumer confidence figures fell more than expected in July despite upward revisions to the index's June figure. And given how important the consumer and housing sectors have been in the U.S. economy's recent recovery, any signs of weakness should have a bigger downward impact on stocks than they appear to be having today.

The big winner on the day is Cisco Systems (NASDAQ:CSCO), up 2.3%. The company got a nice surprise when networking-security company Sourcefire (UNKNOWN:UNKNOWN) reported earnings last night, posting 29% year-over-year revenue growth and beating estimates for both top- and bottom-line growth. With Cisco having announced a week ago that it would buy Sourcefire for $2.7 billion, the news confirms Cisco's overall strategy of seeking out niche companies to acquire in order to create a more complete package of IT offerings for customers.

But energy stocks are losing out after BP (NYSE:BP) reported a lower quarterly profit due to weak world oil prices. The impact on the Dow's energy giants was minimal, with Chevron and ExxonMobil losing less than 0.6%, but BP has fallen almost 4% as investors seem to question whether the company will ever fully recover from the massive financial devastation that the Gulf oil spill wrought.

Finally, Herbalife (NYSE:HLF) has climbed 3.2% after announcing record second-quarter earnings and boosting its guidance for the remainder of the year. An 18% gain in sales produced 8% higher net income, and a big reduction in share counts boosted earnings per share even further. Predictably, Herbalife critic Bill Ackman questioned the results as his losses betting against the company soared, but for now, at least, the company seems to be doing exactly what bullish investor Carl Icahn had hoped it would do.
