thanks for thinking. i'm not saying this to put you on the spot for the halfwits like OP to jeer at, but why not give it the whole nine yards and declare a fair value, either for the enterprise or the common?
it's all just confirmation bias. most security transactions are funds selling to other funds; that's just where the money comes from. so if you like the stock, you can feel good a fund is buying, and if you hate a stock you can feel bad a fund is selling. meaningless
technicals are also confirmation bias. they don't work, and you know they don't work because if they did, goldman sachs would have a machine trading stocks on your technical which would work so fast you wouldn't get a chance. even if they worked, they wouldn't work, which is 100% in line with the historical evidence.
you buy it if you like the prospects for paying a nice dividend in the future, and not otherwise. don't try to outguess morons, last thing you want is to practice thinking like a moron.
god it would be such a shame to lose you on this board. i sure hope you once again completely fail to heed the your own advice. go hide under the bed, it should be safe to invest again in about thirty years, k?
HC. i don't claim to know buffett's mind, but the logical, natural answer to your question is: "increasing returns to scale". brk isn't a conglomerate, it's a reinsurance company. almost from conception, brk has been consistently playing like it's game-plan is to corner the reinsurance industry. it's an astounding display of hubris, if i'm correct, but buffett has the ego to try it and (evidently) the game to pull it off.
