I'm out of my environment here.
For tech traders, we have a saying/rule on how far-reaching we should research.
"If you know the name of the CEO - you know too much"
You will try to find reasons to stay in as the stock is tanking.
That's why I can't get too close in my field.
You can't "fall in love" with a stock, the CEO, or the company's technology or service. If you do, then you might as well be joined at the hip.
