Trying to time the bottom means you're losing out. There's lots of under valued stocks right now if you're looking too buy and hold for a year or more. Most airline stocks are still way undervalued. Even if you missed covid dip they still are going to go up another 30-40% over the next few years.
It might be worth it to wait on the debt default stuff, but I would still say there's many good choices no matter how that plays out... Unless you're in to day trading. Are you investing for long term gains or looking for short term gambles?
