Upside?
On the plus side if an AI bubble bursts there is going to be lots of compute available for cheap. Guessing a timeline on that is hard, but lets say 3 to 4 years*. So right now any contracts for colo or cloud on a 3 to 5 year horizon are unlikely to have dramatic price changes. But if I was renewing a contract in 3 years time, I would be evaluating future compute costs pretty hard before committing to any contract.
as for investing, 3 fold return in 4 years is a pretty big upside, enough that the investors are almost guaranteed to break even and given they measure success by beating the index by a few bps (100th of a %) , plenty of portfolio managers are only constrained from plunging in head first by their Investment Management Agreements with their clients and agreed risk profiles.
I was holding off on any more NVIDIA stock but with announcements like that probably** safe to buy and hold for another 2 years.
* even if the bubble bursts next year there are a lot of contracts running that won't expire immediately, there will be plenty of companies who don't believe it and continue for a while.
** not financial advice, my track record in picking stocks sucks.
