To calculate the average market value of stocks, particularly if you’re looking at a portfolio or a selection of stocks, you would typically follow these steps:

Determine the Market Value of Each Stock: First, ascertain the current market value of each individual stock in your selection. The market value of a stock is typically calculated by multiplying the current share price by the total number of outstanding shares.

Sum Up the Total Market Values: Add together the market values of all the individual stocks in your selection.

Divide by the Number of Stocks: Finally, divide the total market value by the number of stocks in your selection to find the average market value.
The formula can be represented as:
[ \text{Average Market Value} = \frac{\text{Sum of Market Values of all stocks}}{\text{Number of stocks}} ]
For example, if you have a selection of 3 stocks with market values of $1,000, $2,000, and $3,000, the average market value would be calculated as:
[ \text{Average Market Value} = \frac{1000 + 2000 + 3000}{3} = \frac{6000}{3} = 2000 ]
So, the average market value of these stocks would be $2,000.
This approach provides a simple average market value of the stocks in your selection. It’s a useful measure for getting a general idea of the value of a portfolio or a group of stocks, but it doesn’t account for the relative size of each stock within the portfolio. For a more nuanced understanding, you might consider a weighted average that factors in the proportion of each stock’s value to the total portfolio.
