Allocation Opinion

Hello,

I’m a long term investor looking to hold for at least 20 years in a taxable brokerage account prior to starting withdrawals. I’m starting with $90,000 and my allocations are currently:

55% FXAIX
15% FSKAX
10% FNCMX
10% FSPSX
10% VNQ

My question is am I too over/under invested in one market? Any feedback would be greatly appreciated.
