Updated from 2:19 p.m. EDTAmong the many possible answers to the question of what Brown can do for you, the ability to meet Wall Street's estimates would certainly rank high on the list for investors. That wasn't to be Tuesday for UPS ( UPS). The Atlanta-based package shipper, saying it's feeling the pinch of fuel costs, health care expenses and pension outlays, surprised the market by missing analysts' profit targets and offering lackluster guidance for the full year. Second-quarter earnings rose a weaker-than-expected 7.6% from a year ago to $1.06 billion. On a per-share basis, the profit of 97 cents a share in the quarter fell short of the consensus forecast carried by Thomson Financial by 3 cents. Last year, UPS earned $986 million, or 88 cents a share. Near the close, UPS was lower by $9.05, or 11.3%, to $70.95. Not only was the stock plunging, but sellers were showing commitment to their cause, as 18 times the normal number of shares changed hands. About 42.6 million shares had traded, compared with the average volume of around 2.5 million. UPS went as low as $67.25 earlier in the session, just 50 cents above its worst level of the last year. On a conference call after it released its results, UPS management added to the angst by saying they were seeing signs the economy is slowing. UPS, the world's largest parcel carrier, and its chief U.S. competitor FedEx ( FDX) are often viewed as proxies for the overall health of the economy because of their key role in moving goods for companies and consumers. Shares of FedEx lately lost $1.14, or 1%, to $109.30, and the Dow Jones Transportation Average, where both companies are components, lost 1.7%.
