There's an excellent book (you're probably aware of) called The Outsiders. It compares the results of operations focused CEO's like Welch to capital allocators like Buffett, Singleton, and Malone. The thesis is that overtime, the good cap allocators just blow everyone else out of the water.
I was not aware of this one but appreciate the recommendation! I've also been a follower of John Malone's over the years so this sounds like a very interesting read. Added to my list!
