There are many reasons an insider may sell a stock that have nothing to do with their outlook for the share price.
There is only one reason an insider buys shares: they believe the stock price will rise.
Pampa Energia founder and chairman Marcos Marcelo Mindlin is one of the largest shareholders in the Argentine oil and gas producer, holding nearly 14% of its shares. He owns both the Buenos Aires listed shares and the U.S.-listed ADRs (each ADR equals 25 Buenos Aires shares).
That the chairman is buying shares in the open market is a bullish sign. Studies show that insider buying is associated with price gains about 60% of the time, whereas insider selling is associated with price declines less than half the time. This purchase is of Buenos Aires-listed shares, indicating he stepped in to support them at a recent low.
An insider buy like Mindlin's isn't strong enough to be a buy signal on its own. Investors should take the time to evaluate Pampa's business, too.
In that regard, the outlook for Pampa exploration and production in the current fiscal year is strong. Most analysts following the business rate it a 'buy.'
Overall, Mindlin's purchase, along with the company's general outlook, is a bullish signal for investors.
