    You have a great pedagogical style! 👍 The thing I have wondered about modern portfolio theory for a long time is about the way that the expected returns are estimated. Does this really work in the sense that, do the "optimal" portfolio actually perform better on average compared to a reference portfolio, when looking at actual trading data? Perhaps estimating the expected returns as an average of the historical time series is a too simplified model, what do you think about that? I would love some empirical data on this!

    There are a lot of strategies to make tongue-wetting profit that the average joes don't know. . Personally, the financial-market for me seems the only way forward with my long time horizon (accrued roughly $457k in gains since Mid 2021 ) but if you don’t have that fortune of time it’s a tough market out there almost nowhere feels safe!

Her approach is transparent allowing total ownership and control over my portfolio with fees very reasonable in comparison with my investment-income. Also, She covers things like investment insurance, making sure retirement is well funded, Go over tax advantages , ways to have a volatility buffer for investment risk. many things like that.

    Split your portfolio 4 ways. Own "everything" (Stocks, metals, real estate..even crypto.) Sell out of the money covered calls and reinvest premiums. If contracts from on portion are exercised, reinvest the capital into the other 3. Adjust the ratios to maintain a level portfolio.
