On CAPS, 7% of the 862 members who have rated Fastenal believe the stock will underperform the S&P 500 going forward.

Just last month, one of those Fools, All-Star bradford86, touched on the stock's seemingly unsustainable price action:

Fastenal is repping out new all-time highs like it's nobody's business. Sell. Do not think twice. The valuation here is so high that a small misstep will result in lower prices. The chart is parabolic. Target: $30-$40. I'm betting CAPS points on this one coming back down to earth. Since when can you apply a P/E of 40 to a company set to grow at less than 20%? Well, if your answer was: "In your dreams." You'd be right. Mark my words, Fastenal will fall below $40 in the next 5 years.
