On CAPS, 98% of the 2,935 members who have rated Markel believe the stock will outperform the S&P 500 going forward.   

Just last week, one of those Fools, All-Star Manlobbi, succinctly summed up the Markel bull case for our community:

Rather correlated to the S&P500 from one year to the next however (1) low cost leverage from float, (2) marginal equity outperformance, (3) leverage from invested unrealized capital gains and (4) initial price/book multiple of 1.15 versus historical average substantially higher-together will lead almost certainly to outperformance of the S&P500 over say 5 years.

If you want market-thumping returns, you need to put together the best portfolio you can. Of course, despite a strong five-star rating, Markel may not be your top choice.
