Stock buybacks sure seem like a good thing. They reduce a company's share count, granting each remaining share a bigger stake in the company. Suppose, for simplicity's sake, that you own one share of a company with 10 shares outstanding -- a 10% stake. If that company buys back two of its shares, leaving eight shares (including yours) outstanding, your stake in the company just jumped from one-tenth to one-eighth.
But for all the benefits of buybacks, they can carry hefty disadvantages, too.
The dark side
Depending on a stock's value, buybacks don't always make sense -- sometimes, they're not going to yield the biggest bang for a company's buck. If a company with cash to burn on buybacks wanted to reward its shareholders, it could just as easily pay out that moola as a dividend. Or it could pay down debt. Or it could buy another company. Or it could spend the money on more advertising, more stores, more... you get the idea. There are choices.

Buybacks make sense when the stock being bought is undervalued. When the shares purchased are overvalued, the company is essentially destroying shareholder value. There are usually more effective ways to deliver value to shareholders.
Some examples
Tom Jacobs recently tackled this topic at completegrowth.com, quoting the CFO of Luminent Mortgage Capital
Jacobs adds: "Bad reasons are if buybacks are used to reduce or mask the effect of share count increases from options grants, to show 'confidence in our company' alone, etc. These are PR and spin motives that should make you reach for your wallet or purse."
After some number-crunching to determine the merits of certain buybacks, Jacobs concludes that firms making good buybacks include Luminent and Assurant
What to do
The next time you hear that a company you own (or want to own) is buying back its shares, check to see how much of a bargain those shares are.
As Jacobs mentioned, buybacks are often driven by a company's need to offset the increase in its share count caused by stock option grants. This is more common among younger, more rapidly growing companies. To avoid such scenarios, concentrate your stock-hunting among bigger, more established companies. Doing so will often give you the benefit of significant dividends, too.
