I've always thought that berkshire would be a very logical buyer of WTM too. Warren probably wasn't thrilled that WTM was building up Esurance as a competitor to his Geico...but now that Esurance is gone....plus, WTM also exited auto's when they dumped their auto insurance business. Buffet already owns a 20% stake in SYA....just as WTM does. Buffet would like the group of smallish specialty insurance companies that OB owns....and they aren't in P& C anymore........and last is the Re business WTM has, which Berkshire already does business with. But i'm not sure Buffet would pay much above book for WTM. I suppose there's a shot BV could get to 550 next year. But I'm not sure mgmt wishes to sell out, and Buffet does not do hostile. They would want a premium to book I bet.....and I don't think Buffet would pay.
I've traded around WTM.....but backed away for now. I'm hoping for a downdraft back to 420 or so, and will get backin. But I might not get that chance.
