My plan is to invest 85-90% of my money into ETFs, and then the rest into stocks. ETFs are great holdings for someone like me. I've put together a portfolio here and would appreciate feedback on this proposed portfolio: 50% VTI, 20% IEMG, 10% IWM, 10% ARKK, 10% ICLN Is there anything I'm missing here or something that jumps out at you as off?

You are more diverse than me! I'm all US and I get the US bias issue there. Cool you have emerging markets and US small caps. Looks to me like your portfolio reflects your view of the world. The only thing I see missing is bond exposure. Did you mean to leave that out and be 100% equity? That will obviously depend on your risk profile and where you are in life, but if there is a correction, you might want asset class diversification. Disclaimer, I'm not a financial professional.
