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 .
