A complete process of building ten stock portfolio in excel
Creating an Excel spreadsheet with an efficient frontier, tangent line, capital market line, and portfolio statistics involves several steps. I'll provide a general outline for each section, but keep in mind that you may need to adapt the details based on your specific data and preferences.

1. Stock Data:
Create a table with historical stock prices for the 10 stocks in your portfolio.
Include columns for each stock's daily or periodic returns.
2. Portfolio Weights:
Allocate weights to each stock in your portfolio. Ensure the weights sum up to 1.
3. Portfolio Returns:
Calculate the expected return of the portfolio using the weighted average of individual stock returns.
4. Portfolio Standard Deviation:
Calculate the standard deviation of the portfolio returns using the formula for portfolio variance.
5. Efficient Frontier:
Create a scatter plot of various portfolios with different combinations of expected return and standard deviation.
Highlight the portfolios that make up the efficient frontier.
6. Tangent Line:
Identify the tangent line that touches the efficient frontier at the point where the Sharpe ratio is maximized.
Calculate the slope of the tangent line using the formula: (Rp - Rf) / σp, where Rp is the portfolio return, Rf is the risk-free rate, and σp is the portfolio standard deviation.
7. Capital Market Line (CML):
Plot the Capital Market Line by combining the risk-free rate and the tangent portfolio.
The CML equation is: CML: E(Rp) = Rf + [ (E(Rm) - Rf) / σm ] * σp, where E(Rp) is the expected return of the portfolio, Rf is the risk-free rate, E(Rm) is the expected return of the market portfolio, σm is the standard deviation of the market portfolio, and σp is the standard deviation of the portfolio.
