Is Seagate Technology (NYSE:STX) headed higher, or lower?

That's the question we ask when we evaluate insider buying and selling. We ask because how executives spend their paychecks is often a reflection of what they think of their companies' prospects. Here's how CEO Stephen Luczo and his team have spent their money over the past year:

Selling at recent levels has offset earlier buying, which occurred at much lower price points.

What we're tracking here, and why
Insider buying data can be confusing. Here, I'm concentrating only on buying and selling conducted in the open market. With most of these transactions, insiders control the timing. Other times they're buying or selling under the purview of a 10b5-1 plan. Either way, personal holdings are being bought and sold.

Those personal holdings matter the most -- they're the shares executives hold for investment, rather than compensation. Employee stock options are different; they're compensatory in the purest sense. I've stripped out options-related buying and selling from the calculations you see above.

The Foolish view: moderately bearish
Skeptics who had sunk hard drive maker Seagate earlier this year have paid a heavy price. The stock is up more than 250% as of this writing, one of 2009's best performances.

At least one investor did even better than that: CEO Stephen Luczo. He paid $1.8 million for a half-million shares at $3.56 each on Jan. 27. That position is now worth almost $9 million. Congratulations, sir.

If only we were seeing more big bets like this one. Instead, insiders have been taking money out of Seagate. Five of six open market transactions since October have been sales, and some of them have been big. For example, on November 30, board member David Marquardt sold 13% of his direct holdings at $15.15 a share.

We don't know precisely why these insiders are selling. But competition could have something to do with it. Hard drives are a low-margin, commodity business, and Seagate badly trails Intel (NASDAQ:INTC) and others in supplying newer, more functional solid-state drives. Profit-taking at these levels probably isn't a bad idea.
