When insiders buy shares on the open market, their companies could enjoy bullish times ahead. Corporate insiders often have the inside track on their companies' prospects and often have significant exposure to the company's stock through options or restricted shares that are part of their compensation. Besides, insiders probably wouldn't risk plowing too much of their own money into their own company's stock -- reducing their portfolio's diversity and increasing its risk -- unless they thought the stock will rise.

With that in mind, I screened for companies where at least one insider made an open-market buy in the last 30 days. These five consumer durables stocks made the list:

Security

Net Number of Buys

No.  of Shares Bought

Total Value

Market Cap (millions)

Hasbro (Nasdaq: HAS) 7 30,000 $553,000 $5,005
KB Home (NYSE: KBH) 1 15,000 $114,000 $551
Modine Manufacturing  (NYSE: MOD) 16 72,833 $26,000 $526
Winnebago Industries  (NYSE: WGO) 1 1,500 $12,000 $209

When it comes to the number and total value of insider open-market buys, more can be better; I've sorted this table accordingly. Insiders at Hasbro made seven open-market purchases worth a whopping $553,000 while one insider buy at Winnebago Industries was worth a much smaller $12,000. Both are bullish signs, but the purchase of Hasbro, which recently passed three of four "should you buy and hold?" tests my Foolish colleague Jordan DiPietro ran, looks more promising. That said, my Foolish colleague Seth Jayson believes Winnebago's future looks bright. 

Foolish takeaway
Insider buying signals that someone who should be in the know is betting that the stock will rise. You can use this list of recent insider purchases as a starting point for further research -- or a good reason to make a contrarian play.
