Many young technology companies that trade on the Nasdaq stocks have a beta greater than 1. The beta is the number that tells the investor how that stock acts compared to all other stocks, or at least in comparison to the stocks that comprise a relevant index. For example, a gold exchange-traded fund (ETF), such as the SPDR Gold Shares (GLD), is tied to the performance of gold bullion. Consequently, a gold ETF would have a low beta and R-squared relationship with the S&P 500. The company has used its healthy free cash flows to repurchase 40% of its outstanding shares over the past 10 years.

The S&P 500’s 500 constituents will each have different betas based on how they moved in relation to the index over a set timeframe.

How to Use Beta for Investing
Beta can play a big role in portfolio construction and volatility expectations. For example, you can calculate the weighted average beta of the stocks in your portfolio to get a sense of how volatile you can expect your investments to be on a day-to-day basis. Beta can be a useful tool in analyzing a stock, but it has its limitations.
And since short-term traders can profit from big swings in either direction, you can use beta in multiple-day and swing trading strategies. Stocks tend to be more volatile in the short term but produce relatively consistent returns over time. In that case, you’ll be more interested in short-term beta measurements since you have significantly shorter time horizons than a long-term investor planning for retirement. Like most investing factors, the definition of a good beta in a stock depends on each investor’s goals, risk tolerance and timeline. High- or low-beta stocks aren’t necessarily good or bad; they move in different fashions.
Alpha and Beta for Beginners

If you think about risk as the possibility of a stock losing its value, beta has appeal as a proxy for risk. Think of an early-stage technology stock with a price that bounces up and down more than the market.

There is a lot of hope baked into its share price, resulting in wild swings whenever it fails/exceeds expectations and a five-year beta of 2.08, as of July 2023.
The change in price of an option relative to the change in the price of the underlying asset (for example a stock) is not constant. For example, if one purchased a put option on the S&P 500, the beta would vary as the price of the underlying index (and indeed as volatility, time to expiration and other factors) changed. MR stands for the market return, which is the return on the benchmark index you are using. RFR stands for the rate of return on a selected Treasury asset that bears no risk.
You’ll find this alongside other metrics of a stock’s price when doing your research — which you should always do. In a nutshell, beta is a measure of how reactive a stock is to overall market movements – particularly those of the S&P 500 benchmark index.
