I missed this post.
If that's what you believe, you will never invest. I've been investing for 30+ years and the markets are always volatile.
Yet,

I saw his reply, and I'm not knocking him, but I thought the same thing. If you're investing long-term, well.....arguably any time is a good time to put some $ in, but in particular, any downturn is an excellent time. You want to buy at those pullbacks if possible.
At some level, volatility is a good thing, and the markets don't actually move without it. You
want volatility, to an large extent. I tried my hand at day-trading for a couple years, and while I never became great at it, I learned a lot of valuable stuff. I feel like most people don't understand the underlying mechanics of markets and what makes them work and move. But volatility is absolutely necessary. Buyers and sellers
have to overwhelm each other, or prices would never move and correct. The only market that moves up like you want it to is technically a volatile one. Volatility obviously pushes it down as well, but if you're looking at the long term, it's nothing but silly to worry about the downward moves. They're just corrections. That said, if we're talking about the long term, he's not much worse off investing now than if he'd have caught the bottom of this latest swing down. The important thing is just to keep putting some $ in.
