I would argue that Adams Golf (OTC BB: ADGO) is among the most flagrantly undervalued stocks on the market today. As a company on the cutting edge of golf technology, Adams has had tremendous success with its recent hybrid irons. Since 2002, sales have increased from $38 million all the way up to 2006's total of $76 million. For the first quarter of 2007, Adams Golf saw its sales surge 25% year over year and, in the second quarter, launched its new Idea A3 hybrid iron set, the next-generation in the hugely successful Idea line of products. The company is growing rapidly, and the brand appears to be gaining traction; it's the number-one hybrid on the three major tours combined. Adams has been profitable every year since 2003 and, excluding the recording of a deferred tax asset, it trades at around 15 times 2006's earnings.
