Panic selling is something I flushed out of my system in 2008. A week after I poured all our savings into the market, we “lost” 25% of it on paper. It cost me months of discussions at home and foregoing many “this time you sell and never invest again” conversations - ultimately, we recovered and then some. I am a buy-and-hold (is that what they call a hodler?) investor, so trying to be measured on entry, as exit is not in the cards for the foreseeable future.
As a question of principle, what’s the rule of thumb: 1/3 each month till end of year, or all in?
