This is why you have a robust social safety net. Not because the liberals and hippies think lazy people are entitled to free stuff; because everything - everything - is built on faith that the bottom won't ruin "you," specifically.
https://finance.yahoo.com/quote/tvix?ltr=1What's 'a few years' mean to you? The Nikkei hit its high of 40K around 1989-89 and hasn't traded above 80% of that in the 30 years since.
We will continue to provide workers and consumers over the coming decades - economy-wide demand will return once the crononavirus threat subsides.
I'm guessing the above poster meant something more like "period of society-wide economic hardship" by recession. By that more colloquial definition, you might say the great recession lasted through 2014. The stock price plummet, however, was largely finished for most of that period of hardship.
I have no crystal ball; I can't tell you where we are going to be. But if the above poster meant "We're past the plummet, all that's left is the slow climb back to normalcy" then their comment makes more sense.
What you are suggesting is market timing. I am not very good at it, and I don't think most people are. You not only have to know when to sell, but you have to know when to buy back in. You have to get it right twice.
You should not try to time the market. And hopefully you don't really mean "buy back in" (meaning your panicked and sold, you should just be adding/averaging down). Just look for general buying opportunities and don't kick yourself if the market falls a bit further before it rebounds.
To anyone else, recognize that the citizenry is not limited to being passively investing in stocks, yet many of them are when they shouldn't be.
People in all the other markets say "buy the dip" arbitrarily too, and many of those markets are often inversely correlated to the stock market. So just repeating what your favorite investment guru once said does not give you any more insight than the next person.
Sure loss harvesting is nice but those credits still represent money lost, and said loss far exceeds any taxes on gains I'll be making for a while
