Yeah, I'm not on that social media, nor do I read NYT. The same holds for millions of others.
Too bad! Insider trading, as a crime, requires that the information be nonpublic material information. You can join Truth Social and follow Donald Trump, so that makes the information public.
It actually is that broad. Futures traders often rely on industry-specific periodicals, which are “public”. Same for anything in the (high monthly cost!) Bloomberg terminal. So posting on a specific social media platform, where subscribing is free? That’s 100% public.
Except he didn't announce anything. He said "a good time to buy" which may be code language that his friends understand.
… are you hearing yourself? “It’s a good time to buy!” has the plain english meaning “you should buy stock”. Everyone, you included, understood he was talking about US company stocks. Which, if you did, you would have profited. This theoretical code would be “when i say it’s a good time to buy stock, we should all buy stock!”. That is, well, not a code.
He should have announced the policy, and said something like "we will pause the tariffs". But instead, he said something vague, which can be interpreted as a hint, and which will open the road for investigations.
“Now is a good time to buy” isn’t vague.
The point is that this text is not the official policy. It is a hint to investors.
A public hint to investors.
