Interesting post. How'd you buy a horse? A racehorse or a share in a racehorse? Are you actually going to take care of it?
I'll have to look up Buffett's first investments. Berkshire Hathaway, once a shirt maker, was a dog for him but he ended up using its shell. His first homerun was Geico, a money machine that was truly under the radar for years. That's why Buffett loves insurance stocks so much. He owns several.
I don't recall that he owned anything that was a longshot by IHUB standards. Both he and Munger did evolve. I know They tried shorting early on and gave that up. Munger was quite unsuccessful as a money manager on his own before teaming up with Buffett.
