etf portfolio review

Hey y'all,

Decided to create a portfolio of ETFs for long term investing. Decided this (attached ss).

Reasons:
1. ICICI gold etf because of the lower ER compared to Nippon; AUM and volume do be lower but returns will be comparable in the long term anyways. Zerodha goldcase could be great too (lowest ER but it's new still)

Also is there any point in investing in multiple gold ETFs?

2. Silverbees as opposed to tata silver because of aum and volume (huge difference); tata silver is still newer so shouldn't compare in absolute terms

3. Bank, pharma (largest young population so aged ppl will increase), defense because in general bullish sectors for future

4. Mid150 for more coverage


I'm doing an sip w these for the first time; would love to hear inputs. Thanks!
