CNN has a greed-fear index where they look at a few different metrics like the vix, performance relative to moving averages etc. in order to determine the mood of the market.
As you can see we're in 'extreme fear' territory. If there's one thing I've learned over the last ten years, it is that when there is panic in the markets, it is he time to buy.
Now, you could argue that stocks are at about the levels at last year October. So if you didn't love them then, why now?
Well, you can never time the top or the bottom of the market but dipping your toes in now is a lot better than 2 weeks ago. And you don't have to go all in... Start small and build up a position if it continues to drop.
