This reminds me of the last time I was so heavily invested in a stock based on its science. That was ISRG. When that sucker reached $23.00/share (I bought in at $14), I thought, ”wowzers, I made enough money on this bet” and sold. I was really happy about my “killing,” until a few months later I looked at the price… So with COR, I will hang in there until it becomes a blue chip or I am forced to sell because the investment is in an IRA.
