We seem to have an entire generation of people who think "stonks can only go up". Similar views were expressed about houses/real estate in 2007. At 47, I'm probably substantially older than the average HN poster, but having lived through the 2001 dotcom implosion and the 2008 financial crisis has given me some perspective. I'm getting some really bad vibes about the sustainability of the the economy and asset markets…
I'm not denying the existence of bubbles, busts, and crashes, but historically and on average, the stock market does only go up.
This market is overvalued and will likely correct, but that doesn't mean it won't continue to rise on the aggregate.
