semiconductor paycheck + NVDA + QQQ = maybe I need an adult

I work for a supplier in the chip world, so my paycheck already depends on one spicy corner of the market. Naturally I also accumulated NVDA and a semiconductor ETF because apparently I confuse familiarity with diversification.

Today its roughly:
401k target date 44%
VTI 21%
QQQ 14%
SMH 9%
NVDA 6%
VXUS 4%
cash 2%

It's performed great. That is exactly why im suspicious of my own judgment here

Sell some while you still feel clever, not after you feel betrayed

Adult supervision is exactly how that 401(k) feels compared with the rest of the account.
