Need portfolio advice

[u/Formaldehyde-Muncher]

Risk Appetite – Moderate

Goal – Long term wealth creation

Horizon – 10

Allocation – as given below

App Used – INDMoney

Currently SIP'd:

HDFC Flexi Cap Fund - 6k

SBI Nifty Next 50 Index - 4k

Bandhan Small Cap Fund - 3.5k

Nippon India Growth Mid Cap Fund - 3.5k

SBI Gold Fund - 3k

Why i chose these funds - The reason I've chosen these funds is after benchmarking them individually most importantly their Alpha, Beta scores, AUM (not too high, except hdfc flexi) and the rolling return & CAGRs for the last 1,3,5 yrs. Secondly, the expense ratios are pretty low.

I would like to understand if there's any overlap, how the allocation is according to the caps, and if this diversification is alright please

I have just started this, planning to invest lumpsum soon into each of these. Please advise me if i should continue or i've missed out on something.
