Sounds like a legit strategy, but it also sounds like part of it is actively not competing with them.
It was possible to gain by trading on this info when it was news. For the big players, that was 18 months ago, so by now the opportunity to meaningfully trade on this info is exhausted.
For any new information, you can trade on it if you get it at the same time (or before) as the big players, and you can't if you lose in the competition of timely analysis.
Actually this news was tradable by both small and big players. It is larger than all the big traders combined after you factor in risk tolerance.
That is nobody sane puts all their eggs in on basket. There was always the risk that vaccine efforts would have found a vaccine for the disease and stopped it in is tracks. There have always been diseases, most don't spread fast enough to be a problem and it isn't clear in advance which are a problem and which are not.
Emphasis mine.
* Pigs and how to make a buck because of all the ones dying in China. I'm not seeing any good suggestions about how to profit from that for small investors.

The latter seemed an 'in general' strategy and not related to the specific situation with the pork and broader meat industries.
Note I said can. Reading the 10k and 8q and other such forms to find those opportunities is boring. I get paid very well to write software instead and just let an index fund grow my money. I can't live off my investments yet, but when they grow enough I'll be able to [substitute any of a number of hobbies I might get interested in], and it won't be a full time job moving money around.
