Well, there are crashes and there are bear markets. I would say we are in a bear market right now if the stock downturn continues. A dip is a slight pull back, maybe 5% over a few days, followed by an upturn resumption. Those happen regularly and are good buying opportunities. But a big sharp drop like today could also be called a crash. If we get a small bounce tomorrow morning, that could be called a dead cat bounce. They are usually followed by more markets downside.
I don't think we hit bottom yet, or anywhere near bottom in this latest downward trend. The tech high flyers with the high multiples have been the biggest losers so far. But the broader market industrials, incl a lot of good steady eddy companies, have also been swept down with the down draft. Those are often good buys during these times. And in any downturn there are the defensive stocks, usually utilities, telcos and the like, that hold up, or even go up during downturns. The big institutions (banks, funds, etc) often rotate their client money into them.
TSLA, if you are wondering, is in the high flying tech category. So besides tough fundamentals at this time, it is also being caught in the tech downswing.
Personally, I am hoping for another big downturn tomorrow, or at least in the morning. I have my eyes on a few US stocks and ETFs that I may want to buy, but don't wish to catch a falling knife. So will be watching for some type of bottom, even if it looks like a short term flattening out. I tend to trade frequently in times like this, and will not hesitate to sell if it looks like it will drop further.
I liken a bottoming to a bouncing ball. First you get a big bounce followed by smaller and smaller ones until it rolls flat. Of course still have to watch it doesn't roll over a cliff again. But that's when you really watch fundamentals and outlooks as well.
I have been trading like this for a few decades, which basically allowed me to retire very early. Even when I was still working there were some years I made more money from my trading than from my work. I have slowed down now, though, and generally only trade when the opportunities are very obvious, like now.
BTW, your financial advisors will always tell you to hold and you can't time the market. There are good reasons why THEY say that, but that's another long story. I fired mine decades ago, and never looked back.
Anyway, definitely some opportunities out there now, and more to come. Take your pick....
