I'll be perfectly happy if this buyback bump is a nonevent. Berkshire the stock under-performed Berkshire the company so far in 2018, but I'm not sure that was the case in 2013, 2014, 2016, or 2017. It seems like there have been many more undervalued spots in recent history than there are right now so I don't see why Buffett would be rushing to buy back shares hand over fist right now. It would be great if some more China fears, Gates Foundation sales, and disappointed speculators drop the stock back under 200 for the foreseeable future.
I don't want to see a crash, but I just don't want the stock to look fully valued as it will be harder to buy new shares when money becomes available. I have a lot more shares I want to buy over the next 10+ years, and I wouldn't want to be competing with the Company for shares, especially not over $200.
