All markets respond to changes. If more investors followed Martin's advice, the market would stabilize and return to new normal. Then someone else would come along to take advantage of the new status quo. The problem for following Martin's advice is this:
- He is telling people what they already know.
- Most of what he says is irrelevant to any investing, and is so wrong it isn't funny.
- It is nonsense layered in confirmation bias ("the EU banking system has to collapse").
- He is making it up to draw people in to buy from his store.
- Divination has better accuracy than his Socrates "AI".
Martin made three good predictions about economic downturns during 1980s. That was it, and that was 40 years ago. Everything since then has been crap or worse. He did not take a plea deal over running a Ponzi scheme because he was making better investments than anyone else.
As for the claims of his accuracy which he himself has made, here is a list, of Armstrong's Major failed Predictions and The Failed Emerging Markets Meltdown Prediction
A stopped clock is right twice day. The other 8.46x10-16s - 2x10-20s the clock is wrong.
