Portfolios on CML are perfectly diversified - have only systematic risk.
For individual securities and not fully diversified portfolios

Only bearing systematic non-diversifiable risk rewarded by market.
Beta and the characteristic line
In practice beta of an asset estimated by regression of asset’s returns on market returns. The estimated regression line = characteristic line.
Market efficient:
- operationally (runs smoothly)
- informationally = prices fully reflect all available info at all times
Efficient market hypothesis (EMH)
- Weak form efficiency= prices fully reflect the info contained in all historical market data (prices, volumes and similar figures).
- Semistrong =prices fully reflect all public info.
- Strong= prices fully reflect all info (public + private)
THE PRACTICAL CONSEQUENCES OF THE EMH
- If weak EMH true: technical analysis (predictions from historical market data) useless
- If semistrong EMH true: fundamental analysis (using all public info) useless
- If strong EMH: laws prohibiting use of insider info pointless since all inside info is in prices already
