Of course the answer is "it depends". Goals, risk tolerance, amount of time you want to spend investing, time frame for your investments, your own expertise, your passion your network...so many factors impact this decision.
For me, right now in my life, I'm moving towards 50% of my investments in a brokerage account managed by a very trusted fee-only (no commissions) financial planner and 50% in real estate. From there it is something like:
50% in Brokerage
- 60% stocks, 40% fixed assets (bonds, cash and even a very small percentage in gold funds and lumber funds)
-everything is in low fee index funds
-all assets are held in the most tax efficient account types (i.e. IRA, old 401k) for the asset that is purchased
-diversification across asset classes, US/International
*This is boring as all get up. I have nothing to do and own so little of any one company that it not even worth cheering for them.
50% in Real Estate (where I'm heading)
-split (not necessarily evenly) between my own apartment buildings, other syndicated investments, possibly notes are hard money lending
