What is the form of a simple linear regression prediction equation?

It is $\hat{y}=a+bx$, where $a$ is the intercept, $b$ is the slope, and $x$ is the predictor.

What does a strong positive correlation between two financial variables indicate?

They tend to move in the same direction in the observed data; correlation alone does not establish causation.

How is a stock's beta estimated?

It is the slope from regressing the stock's returns on benchmark returns.

What does a beta below 1 indicate relative to a benchmark?

The stock had lower estimated sensitivity to benchmark movements over the analyzed period.

What does beta measure about investment risk?

It measures sensitivity to market-related, or systematic, risk; it does not capture every source of risk.

Summary

Regression can help describe and forecast how one financial variable changes in relation to another. In this lesson, we use monthly DJIA and Russell 2000 closing values to build a simple linear model.

Here, $a$ is the intercept, $b$ is the slope, and $\hat{y}$ is the model's predicted value of $y$ .

In the index example, the DJIA is assigned as the independent variable ( $x$ ), and the Russell 2000 is the dependent variable ( $y$ ). The question is whether DJIA values are associated with Russell 2000 values and whether the fitted line can estimate the latter from the former.

Quiz questions

To estimate a stock's beta by regression, which variable should be the predictor?Answer: The benchmark's returns
In a regression of stock returns on benchmark returns, what does the slope estimate?Answer: The stock's beta relative to that benchmark
A stock has an estimated beta of 0.83 relative to a broad market benchmark. What does this suggest for the analyzed period?Answer: Lower estimated sensitivity to benchmark movements
Why are returns used rather than raw stock and index price levels in a typical beta regression?Answer: Beta describes how stock returns relate to benchmark returns
Which statement best describes a beta estimate based on historical observations?Answer: It summarizes past sensitivity and may change over time
