Late last month, sTucKatsPEicheR described Alleghany in simple bullish terms: "Great company being [run] by very bright minds. Have shareholder value in mind."

In a pitch from October, MJKpayday highlighted the stock's cheapish valuation as a remarkable long-term opportunity:

Over the next few decades, Alleghany is set to become one of our nation's most admired, loved, and profitable larger insurance and holding firms along with Markel, White [Mountain], and their mentor, Berkshire Hathaway [NYSE: BRK-A]. Over the last few decades the price of Alleghany has oscillated back forth around it's true value and today represents the most extreme outlying point since its inception, offering an opportunity to ride both the potential for a near term return to more common price to value ratios, and the company's 2 decade long trend of increasing book value.
