Should You Imitate the Insider Buying at Walgreen Company (WAG)?

A Form 4 filed with the SEC has disclosed that a corporation connected to Walgreen Company (NYSE:WAG) Board of Directors member Stefano Pessina, who became a billionaire from managing healthcare company Alliance Boots, purchased over 83,000 shares on April 19th at an average price of $48.62 per share. Studies show a small outperformance effect for stocks bought by insiders (read our analysis of studies on insider trading). Our explanation for this is that insiders have an incentive to diversify their wealth rather than increase their company-specific risk, and so buying more shares should serve as a vote of confidence in the stock price.

Walgreen Company (NYSE:WAG)’s most recent fiscal quarter ended in February, with the company showing essentially no change in revenue or operating income ex-special items compared to the same period in the previous fiscal year (earnings were up, but this was due to these special items rather than actual improvements in business conditions). Cash flow from operations in the first half of the current fiscal year has been similarly flat. However, Wall Street analysts expect the company’s net income to increase going forward. As a result, the $47 billion market capitalization- which represents a trailing earnings multiple of 22- comes out to only 13 times consensus estimates for the fiscal year ending in August 2014. The stock is up 36% in the last year, possibly linked to the resolution of the drugstore’s dispute with partner Express Scripts Holding Company (NASDAQ:ESRX).
