I recently got rid of my financial advisor I used for 4 years. Now that I’m on my own, I’m wondering if it’s necessary to have my brokerage account and my 401k so spread out among different funds. I’m currently 40 and don’t plan on touching any of this for at least 15 years (401k will be more like 25 more years) so not looking for too much conservatism in my investments as of now.
