Stock Market

Good on ya,
Some folks only look at the statements, and think they have no choices, or stick with a "dog" fund.
You chose wisely, for you, but keep an eye on it, and maybe look , just for kicks at the performance of the alternative funds offered by that institution, you may be shocked.
See if their "tech" fund maybe tripled, consider selling half of what you got for some of what you missed.
There are also tools to prevent "huge losses", but diversification is important, " all eggs in one basket", is never wise .
I don't remember the name of the company, but a few years ago it's employees put their majority investment into the company and when they went out of business they lost big time. I don't feel 100% sorry for them as they should have never put all of their money into company stock. A good investment group should've advised them not to do so. I'm a firm believer in putting money into different investments. I hate that happened to those people but some of it was their own fault by putting all of their eggs in one basket
