You have to ask " What changed?" In the dot com crash people got laid off left and right. In the real estate crash, banks stopped giving out ninja loans. I don't see a sign yet that anything is turning around. If I saw a bunch of zombie companies going under that would probably convince me. https://slaythespider.substack.com/p/zombie-companies
Never believe anyone who says we're at a bottom. Or a top. Try not to even hear the people who say such things. It won't improve your trading.
