Below is just one fictious example, on asset allocation for a portfolio, allowing consistent cash flow per year, while still investing large% of the asset into stocks (both index and individual stocks).
The exact % amount is made up here for illustration purpose. It is not important because the key point is proper asset allocation and risk control.
Income: Bond, Divident, Muni: 10%
Index: SPY/QQQ: 30%
Growth: Large cap leaders: 60%
