If you own shares in Reliance Power Limited (NSE:RPOWER) then it’s worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. Modern finance theory considers volatility to be a measure of risk, and there are two main types of price volatility. The first category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. The second sort is caused by the natural volatility of markets, overall. For example, certain macroeconomic events will impact (virtually) all stocks on the market.
Some stocks mimic the volatility of the market quite closely, while others demonstrate muted, exagerrated or uncorrelated price movements. Beta is a widely used metric to measure a stock’s exposure to market risk (volatility). Before we go on, it’s worth noting that Warren Buffett pointed out in his 2014 letter to shareholders that ‘volatility is far from synonymous with risk.’ Having said that, beta can still be rather useful. The first thing to understand about beta is that the beta of the overall market is one. A stock with a beta greater than one is more sensitive to broader market movements than a stock with a beta of less than one.

What does RPOWER’s beta value mean to investors?
Looking at the last five years, Reliance Power has a beta of 0.82. The fact that this is well below 1 indicates that its share price movements haven’t historically been very sensitive to overall market volatility. If history is a good guide, owning the stock should help ensure that your portfolio is not overly sensitive to market volatility. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall. You can see Reliance Power’s revenue and earnings in the image below.
Could RPOWER’s size cause it to be more volatile?
Reliance Power is a small cap stock with a market capitalisation of ₹78b. Most companies this size are actively traded. Small companies often have a high beta value, but they can be heavily influenced by company-specific events. This might explain why this stock has a low beta.
What this means for you:
The Reliance Power doesn’t usually show much sensitivity to the broader market. This could be for a variety of reasons. Typically, smaller companies have a low beta if their share price tends to move a lot due to company specific developments. Alternatively, an strong dividend payer might move less than the market because investors are valuing it for its income stream. This article aims to educate investors about beta values, but it’s well worth looking at important company-specific fundamentals such as Reliance Power’s financial health and performance track record.
