This is "the memory shortage that no one saw coming." To the best of my knowledge, no podcasters, bloggers, or experts in AI predicted this or were sounding the alarm of a memory shortage. No one was saying pre-2025 to buy memory/data storage stocks. This goes to show how hard it is to predict. Everyone was saying to buy NVDA, which had done well from 2022-2024, and then stalled out, only to be surpassed by memory stocks like SanDisk, Western Digital, and Micron, which took many by surprise.
There were some. Read SemiAnalysis.
I picked up some Micron last year anticipating memory demand, but then the stock went down for a while. I waited, it went up and I took 25% profit as I figured they couldn't add any new capacity and would have sold all the capacity from their existing fabs on long term contracts. Then prices went crazy, sigh.
I'm not sure why prices have gone boom now rather than before given we're years into the LLM boom, but probably it's to do with capacity lockups expiring or something similar.
