This scatterplot compares individual observations. The envelope is not an optimised portfolio frontier; no covariance matrix or portfolio weights are estimated. The slope is illustrative, not a capital market line. The fixed hurdle is a comparison assumption, not a current risk-free quote.

Annualised return is compounded from first to last observed adjusted close. Annualised volatility is the sample standard deviation of observed daily adjusted-close returns multiplied by sqrt(252). All eligible securities are displayed; no alphabetical sampling is applied.
