Akre and Armstrong have had large buys in the last 12-14 months. Now you are going to tell me Akre doesnt know what he is doing! And no I see nothing strange in the income statement. If you do you just dont understand their business.
None of the alleged "large buys" you claim, were open market purchases.
The single "large" purchase by Akre was picking up shares of other insiders/officers who sold the large amount of shares.
Armstrong never made any open market purchases above 372 shares. Option exercises do not count as purchases - especially when the stock price it takes place at is $70+ lower than the current market price.
Keep convincing yourself that this is such a wonderful investment because of what others do.
