That would be falsifiability, if you agree that yes you will agree that you fell for a conspiracy theory, in that situation.
If you make up an excuse, then by definition, your opinion is unfalsifiable.
And being prepared to hold for a long time is key. Here's why: let's say it's true. Let's say that hedge funds did engage in naked shorting of a company seemingly headed for the dust bin. If this buy, register and hold strategy was for only x months, then the hedge funds can wait to close out their position. Right? Is that confusing? By saying, "There's no end," it puts tremendous pressure on these hedge funds.
I've listed several places where the markets have been shown to be corrupt and rigged. People still go to jail for insider trading but not for any of these other, much worse, market manipulations? And you ignored it. What has incurred your wrath, instead, is that a large group of people would buy, register and hold a stock they like and not state unequivocally when they were going to sell. That's what has made you mad.
The math of all of this is that either don't understand what I'm saying or you do, which means you're either a little fool or a giant asshole.
If you do not have a timeline for your predictions of financial doomsday, then that by definition means that your predictions are unfalsifiable. Which is the problem there I have trying to bring up this entire time.
It is a big problem, if you are literally saying that no matter how long goes on, without the doomsday happening, then you will just make up an excuse for why the doomsday got delayed.
That is a problem, because then the belief is not falsifiable.
