General Electric, Tyco And Others Insiders Have Been Buying

With the markets still near all-time highs but facing various headwinds, investors have had to get more selective when it comes to picking stocks. Insider buying can be an encouraging signal. Conventional wisdom says that insiders and beneficial owners really only buy shares of a company for one reason -- they believe the stock price will rise and they want to profit from it. Recently, the most significant insider buys have been of the likes of General Electric, Opko Health and Tyco International.

AGCO

Completing a more than month-long binge, one director bought more than 9,700 AGCO Corporation AGCO shares in the past two weeks at prices ranging from $47.89 to $47.99. That came to more $486,000. The total for the entire month of April was around $19.0 million. This Georgia-based agricultural equipment maker has a market capitalization near $4.5 billion and a dividend yield of about 1.0 percent. The price-to-earnings (P/E) ratio is less than larger peers Caterpillar or Deere, but more than 19 percent of its float is short. Shares ended Tuesday at $51.07, so the buys look well-timed.

As the European Commission expresses concerns about a General Electric Company GE buyout of Alstom, two GE directors bought a combined 43,500 shares last week.
