Anyone researching Parenteral Drugs (India) Limited (NSE:PARENTLD) might want to consider the historical volatility of the share price. Volatility is considered to be a measure of risk in modern finance theory. Investors may think of volatility as falling into two main categories. The first type is company specific volatility. Investors use diversification across uncorrelated stocks to reduce this kind of price volatility across the portfolio. 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. Some investors use beta as a measure of how much a certain stock is impacted by market risk (volatility). While we should keep in mind that Warren Buffett has cautioned that 'Volatility is far from synonymous with risk', beta is still a useful factor to consider. To make good use of it you must first know that the beta of the overall market is one. Any stock with a beta of greater than one is considered more volatile than the market, while those with a beta below one are either less volatile or poorly correlated with the market.

What does PARENTLD's beta value mean to investors?
Given that it has a beta of 0.82, we can surmise that the Parenteral Drugs (India) share price has not been strongly impacted by broader market volatility (over the last 5 years). This suggests that including it in your portfolio will reduce volatility arising from broader market movements, assuming your portfolio's weighted average beta is higher than 0.82. Many would argue that beta is useful in position sizing, but fundamental metrics such as revenue and earnings are more important overall.

How does PARENTLD's size impact its beta?
With a market capitalisation of ₹218m, Parenteral Drugs (India) is a very small company by global standards. It is quite likely to be unknown to most investors. Companies with market capitalisations around this size often show poor correlation with the broader market because market volatility is overshadowed by company specific events, or other factors. It's worth checking to see how often shares are traded, because very small companies with very low beta values are often only thinly traded.
What this means for you:
The Parenteral Drugs (India) 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 Parenteral Drugs (India)’s financial health and performance track record.
