Getting out of the market is never a good idea

I used to think that getting out of the market (meaning liquidating your long positions into cash) was a good idea if you feel the market as a whole is overvalued. But what ive realized over the past years is that this makes you subject to 'market timing' which has been known to not work. No one can time the markets, if they could they'd be crorepatis. Waiting for a market correction or a crash so you can buy companies at excellent bargains seems tempting but you run the risk of losing out on opportunities that are available now, even in bull markets.

Also cash has a very low rate of return, so keeping cash means you don't even beat inflation at those rates.
