Is it possible to estimate a beta value of a time series data (stock) using the CAPM model on NumXl?

  Check out the white paper on calculating CAPM beta using the regression functions in NumXL

  To estimate the CAPM beta, you need to regress (SLR) between the two-time series: market returns and your asset returns.

  Asset Return = risk-free return + beta * Market Return

  You can use the NxRegress function to compute the slope (i.e. Beta) for the two-time series. See the function reference page and example:

  You can even compute the beta value for different dates (using prior data) and examine the variation of beta over time.
