No, in my opinion. But not because I don't think it's a promising technology announcement or a good company, but because a casual reader of articles on HN is not positioned to compete with the professional analysts.
They mentioned that they'd be hosting an event with innovation announcements months ago. Some traders would have been buying WD stock in anticipation of that event, and wagering whether or not that included MAMR, HAMR, etc, and what each of those possibilities would mean to the company outlook.
The event and the article describing the MAMR breakthrough were posted yesterday at 9:30 AM PT. Your 'window of opportunity' to respond to the article was the few moments it took to figure out which of your guesses about what they'd announce were confirmed or refuted at the event. Even then, you may have been reading it literally by eye, while your competition was parsing it with NLP, using a gigabit connection and server located near the wdc.com servers, or perhaps using ones near the stock exchange.
As a result of this preparation, concurrent with the announcement and market open, the stock 'jumped' from 84.27 to 86.22, and a somewhat remarkable volume of 917k shares were traded instead of their daily average of 144k shares, but have since moved around a bit and are gradually settling in:
In short: you're literally 24 hours behind the real market. Don't try to play it minute by minute based on Anandtech or HN publications.
But don't let that discourage you from buying companies based on what you believe their long-term outlook to be. Or maybe do that, and just buy into mutual or index funds instead.
Its highly unlikely that an algorithm, however sophisticated can project the outcome of such an announcement in such a short time.
But discussions like this on a news/analysis piece by a fairly technical new source combined with above average human intelligence will project a more likely outcome.
The stock may go up on this news like you mentioned. But it more often than not settles down. But if OPs time horizon is medium term(a few quarters) or more, then its worth investing on such news.
I assume that the OP might have a more long-term strategy in mind. If they can bring this to market quickly, it certainly is an advantage over the other HDD manufacturers, which might hold for a while. That's not necessarily priced in yet.
