Already diversified across equity SIPs, unsure where to put the next one

Hey everyone, I’m currently investing through **4 SIPs** across different mutual fund categories: * Small-cap funds * Mid-cap funds * Flexi-cap funds * Digital/sector-based fund This gives me decent equity exposure, but now I’m thinking of starting **one more SIP,** and I’m a bit confused about where it makes more sense to put this money. The two options I’m considering: 1. **Index Fund SIP** (Nifty 50 / Nifty Next 50, etc.) for stability and long-term compounding 2. **Gold / Silver / Metals SIP** for diversification and hedge against market volatility Would love to hear how you’d approach this?
