What is a high beta index?
A high beta index is a stock basket with higher volatility than a broad market index like the S&P 500. The most famous index is the S&P 500 High Beta Index. It monitors the 100 S&P 500 firms most susceptible to market returns.
Beta refers to an asset’s volatility or systematic risk compared to the market. In addition to the large-cap index, Standard & Poor’s provides high beta variants for small-cap, mid-cap, and other market indexes.
The Explanation of High Beta Index
High-beta index firms are more sensitive than the market. A stock’s beta measures its sensitivity. A 1 beta means the asset moves with the market. Assets less than 1 are less volatile than the market, while those more than 1 are more volatile.
An asset with a beta of 1.2 is 20% more volatile than the market. The theory says a beta of 0.70 is 30% less volatile than the market—beta measures performance versus a popular index like the S&P 500.
Invest in an exchange-traded fund (ETF) to gain exposure to an index. The frequently traded Invesco S&P 500 High Beta ETF (SPHB) analyzes market volatility. The ETF has underperformed the S&P 500 Index since its launch.2. Financial businesses, such as Discover Financial Services (DFS), Lincoln National Corp. (LNC), and Invesco (IVZ), make up approximately 30% of the fund’s assets.
The limitations of this Index
Contrary to common opinion, high beta or volatility doesn’t guarantee higher profits. Historically, the High Beta S&P 500 Index has underperformed its benchmark. This happened during a steady market improvement.
However, research suggests that low-volatility stocks yield higher risk-adjusted returns. Low beta tends to outperform due to investment behavioral biases, including the representative heuristic and overconfidence. Sector selection and other fundamental factors affect this index’s volatility and performance.
