reasoning
The fundamental relationship between risk and return in capital markets can be expressed as:
$$E(R_i) = R_f + \beta_i \left( E(R_m) - R_f \right)$$Where:
- $E(R_i)$ = Expected return on asset i
- $R_f$ = Risk-free rate
- $\beta_i$ = Beta coefficient (systematic risk)
- $E(R_m)$ = Expected market return
This Capital Asset Pricing Model (CAPM) shows how context (market conditions) plus data (historical performance) plus action (investment decisions) determine information value in financial markets.
For Angola’s emerging market, the volatility factor becomes: $\sigma = \sqrt{\frac{1}{n-1}\sum_{i=1}^{n}(R_i - \bar{R})^2}$
