I read somewhere that the best investor is the lazy investor. One who does dollar cost averaging and only looks at his or her portfolio occasionally. One that does not panic but stays the course.
I took a glance at our portfolio last week, then closed out and vowed to not look at it again until this crisis is over and the market settles down. We moved into a more conservative portfolio last spring because we are entering the distribution stage in the next year or two. So the loss was not as bad as it could have been if we had kept the original allocation. But of course a loss is not really a loss unless you cash out.
BTW, we are in index funds and the rebalancing is done for us at Schwab. So our account is on automatic pilot.
We are fortunate that I have a pension, my husband has social security and we have a couple of annuities. So we are going to sit tight, stay frugal and ride this out.
