A little background:

22yr old beginning to invest in stocks, ETFS, Retirement, etc

I currently have a taxable brokerage account, Roth IRA, 401k(split between Roth and traditional) and finally an HSA all with Fidelity. I actively contribute to all of them. I max out my Roth IRA and contribute to my employer match for my 401k at the bare minimum. Rest of the money goes into the taxable account.

My current brokerage account is all stocks. The usuals(AAPL, DIS, BABA, etc). My Roth IRA will mainly be mutual funds(FZROX, etc) and MSFT. I mistakenly added MSFT to my Roth IRA and since it’s a long term hold anyway, I don’t feel like selling and rebuying in my taxable account. I want to open a second brokerage account specifically for ETFs. Haven’t decided the ETFs yet but looking at VOO or an equivalent, WCLD, maybe ARKK.

My question is, is this a good or bad idea? Is it too many accounts? Any other ETFs suggestions? Any other suggestions in general?

Thanks in advance
