Watching insiders is like participating in a weeks-long stakeout. You expect something to happen, but you don't know what. So you settle in, sip your coffee, and wait for clues to solving the big case.

Here, the "case" is direction: Which way is your stock headed? The "clues" come in the form of insider buying and selling action. Have a look at Coca-Cola (NYSE:KO) over the past year.

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: Bullish
Is there any stock out there more deserving of the moniker "no-brainer buy" than Coca-Cola? After more than a century in business, you'd think investors would have come to appreciate its global distribution network, steady growth, and predictable dividend payments.

You'd think, but you'd be wrong. The Wall Street Panic of 2008 torched everything, including shares of Coke: The stock trades for 46% above its 52-week low of $37.44 a share as of this writing.

Coke's business hasn't changed much since. A distribution deal with Hansen Natural (NASDAQ:HANS) remains, and the stock continues to yield better than 3% annually in dividend payments.

Executives and board members like that story, but they liked Coke most when others hated it. CEO Muhtar Kent and director Barry Diller bought shares in early March, within spitting distance of the year's lows. Diller, in particular, spent close to $20 million to add to his Coke stake, which had consisted of just 1,000 shares.

But there's more to this story than just good timing. From February to May of last year, three separate insiders bought shares for more than $55 apiece. Motley Fool Inside Value advisor Philip Durell calls Coke one of his service's "core" picks. The implication? This is a stock to buy to hold for a lifetime, and then pass on to heirs.
