What Risk Means for a Shareholder
Begin with uncertain outcomes and the shareholder's residual claim, then inspect the same stock through three different risk lenses.
Define equity risk, follow the shareholder claim, and build a three-lens risk map before measuring anything.
Risk is exposure to uncertain outcomes. Actual shareholder results can finish above or below what the investor expected.
Start with uncertain outcomes
Risk is exposure to uncertain outcomes. An expected return is the probability-weighted average result; the actual return is the result that occurs.
The actual return matches the investor's expected return.

How this lesson uses themShowHide
Source-authentic claims follow Damodaran's 38-webcast Investment Philosophies course, Session 3 of 38: Understanding Risk II — The risk in stocks. All 18 slides, the complete official caption track, and the test and solutions were audited. OPS corrects the source's false Chinese-character etymology, uses the slide's weekly regression frequency, and rewrites two defective assessment items. The Northstar and scholarship-fund interactions are original OPS pedagogy; no live market data.
