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 it's 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 I'm suspicious of my own judgment here.

When job risk and market risk are dating each other, I get nervous.

At least you have almost half in a target date fund acting as adult supervision.

This is one of those works until it very much doesn't setups.

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

Adult supervision is exactly how that 401k feels compared to the rest of the account.

The good performance is what makes concentration seductive.
