It is never "fun" to live through a market sell off while you are long the market. However, I believe this particular pullback is very healthy. The market can't go up in a straight line and, therefore, sell offs and pullbacks are natural market occurrences. It wouldn't surprise me if this particular one pushed the S&P 500 down to 1,900. And if panic starts to set in, it is possible the S&P goes down to 1,800.
Mentally, I believe, investors need to be prepped and ready for this kind of volatility. Furthermore, if they are prepped and ready for this kind of a move...they should be in position to profit from it when the dust settles.
