For single stocks, drawdowns like this aren’t uncommon. According to JP Morgan, between 1980 - 2020, roughly 45% of stocks that were ever in the Russell 3000 fell 70% or more from a prior peak and never recovered. Almost a coin toss.
So if you aren't planning to make a change, what’s the point of looking? If there's a reason to trade, make sure recency bias isn't influencing the decision.It can be tempting to make changes to your portfolio after recent events.
