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 category is company specific volatility. This can be dealt with by limiting your exposure to any particular stock. The other type, which cannot be diversified away, is the volatility of the entire market. Every stock in the market is exposed to this volatility, which is linked to the fact that stocks prices are correlated in an efficient market.
Some stocks see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated 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 we can learn from PARENTLD's beta value
Looking at the last five years, Parenteral Drugs (India) 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. 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. You can see Parenteral Drugs (India)'s revenue and earnings in the image below.
Could PARENTLD's size cause it to be more volatile?
Parenteral Drugs (India) is a noticeably small company, with a market capitalisation of ₹116m. Most companies this size are not always actively traded. 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:
Since Parenteral Drugs (India) is not heavily influenced by market moves, its share price is probably far more dependend on company specific developments. It could pay to take a closer look at metrics such as revenue growth, earnings growth, and debt.
