One of my stocks dropped 40% in 2 days, how should I mentally approach this?
If you own the stock today, it doesn't matter what it traded for yesterday.  If XYZ is trading for $40 and you own it, ask yourself if it's worth buying today for $40.  If it isn't, you may want to consider selling it and buying something that is worth $40.
