|Lots of predictions have bitten the dust. One poster proclaimed ‘the bottom was clearly in’ on 8/17/2018 when it closed at $63.64.
I haven't bothered reading your link, but wouldn't put any credence in price predictions, which are pretty much meaningless.
The prediction I referenced was one about the fundamentals of the market, which is a basis of learned investment selection. NAND rules, and will for a LONG, LONG time to come. Disk drives also have huge growth ahead, while most consider it dead.
That being said, anyone who bought on 8/17/18 is ahead of the game, and well positioned for the hypergrowth ahead.
As always, do your homework, be nice, and always use protection.
