Hydraulic equipment-maker Eaton ( ETN) disappointed investors with its third-quarter report Monday, which sent the shares down 4% that day. The company earned $1.67 a share (excluding one-time items), which was a penny below the consensus analyst estimate. Revenue grew 7% year over year to $3.3 billion, which was $60 million ahead of expectations, but management's fourth-quarter profit guidance of $1.65 to $1.75 a share was well short of the previous $1.85 consensus estimate. Eaton blamed slower demand in the heavy-duty truck market and weak new-home construction activity for the lower earnings. That said, the stock has bounced back, closing Wednesday's at $95.67 on the back of two analyst upgrades. While trading 9% off their 52-week highs, Eaton shares remain up 29% for the year. Given Eaton's bumpy ride of late, I'm here to answer readers' questions: Should you buy shares in Eaton? Is it time to buy Eaton's stock on a pullback, or do the shares have further to fall? Through acquisitions, Eaton has become a leading manufacturer of everything from engine components and control systems for automotive and aerospace customers to being a top maker of golfclub grips. According to Bloomberg, the company has made 11 acquisitions in the past year. And management said on Monday's conference call that it's eyeing more potential acquisitions. But even as these purchases are growing Eaton's top line, the company's earnings growth is slowing. Following the latest guidance cut, Eaton is now expected to deliver just 7% profit growth this year, compared with 19% in 2006 and 25% in 2005.
