On CAPS, 97% of the 534 members who have rated AmTrust believe the stock will outperform the S&P 500 going forward. These bulls include Stender89 and JPNot.

Less than two months ago, Stender89 advised Fools to trust in AmTrust: "This is just a beautifully run business in the very likable insurance industry. Low combined ratio, shareholder-focused management with huge stake in the company. Count me in."

In fact, AmTrust's three-year average return on equity (21.7%) easily bests that of insurance rivals Assurant (11.7%), Travelers (12.9%), AIG (-50.5%), and even longtime Foolish favorite Markel (5.1%). To be sure, AmTrust's shares currently seem to reflect that operational edge, trading at a price-to-book premium to each of those same competitors. Of course, with as many positives as JPNot believes it has, AmTrust could still be a reasonable long-term opportunity:

The company operates in three segments: Small Commercial Business, Specialty Risk and Extended Warranty, and Specialty Middle Market Business. The company does a lot of worker's comp insurance for really small companies who are less likely to lay off workers, so they seem to have a good niche going. Here is another great growth company with a low PE. ... Company has some debt, but pays a nice dividend.
