> This belief that Wall Street is always correct is exactly what caused the previous economic crash.

Speculators != Investors.
> If people are buying, it doesn't matter if you don't agree .. you have to buy as well it works as a hedge.
No. If other people are buying, you can sit there and do absolutely nothing.
