What Are Insiders Buying Right Now? Try Real Estate

Back in April, I wrote a piece on interpreting insider buying and selling. And yes, it bears repeating that this is distinctly not the “Martha Stewart (NYSE:MSO) kind” of insider trading that will land you behind bars but rather the perfectly legal variety. The SEC requires all company officers, directors, and shareholders owning 10% or more of a company’s voting shares to disclose any dealings they have in their company’s stock. If the CEO of the company is buying — or selling — the stock of the company he manages, the SEC believes the investing public has a right to know.

Company insiders tend to be fairly decent value investors. They don’t get every bend and twist in the stock price right, but they tend to be large buyers near major market bottoms. And near tops, their buying tends to trail off.

Take a look at the recent data, courtesy of GuruFocus , which aggregates insider buying across the S&P 500. A chart reading below 100% means there is more selling than buying, and you’ll see that this is a general rule. Under normal market conditions, insiders tend to be net sellers of the shares they accumulate via stock-based compensation. It’s when their trading deviates from this norm that things get interesting.
