I hold shares of 5 tech companies in the top 10 by market cap. I've had them for 10 years and they were buy and forget, one time purchase, all in.
However, I've seen them go from 30k to 50k, then to 40k to 60k, then 60k to 30k and then to 90k to 70k.
I am patient but feel I should be doing more here. What is the general advice on this? I hold a small vanguard global all cap fund too.
