Anyone researching Alpa Laboratories Limited (NSE:ALPA) 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. First, we have company specific volatility, which is the price gyrations of an individual stock. Holding at least 8 stocks can reduce this kind of risk across a portfolio. 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. 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 ALPA's beta value mean to investors?

Zooming in on Alpa Laboratories, we see it has a five year beta of 0.83. This is below 1, so historically its share price has been rather independent from the market. If history is a good guide, owning the stock should help ensure that your portfolio is not overly sensitive to market volatility. Share price volatility is well worth considering, but most long term investors consider the history of revenue and earnings growth to be more important. Take a look at how Alpa Laboratories fares in that regard, below.

Could ALPA's size cause it to be more volatile?

Alpa Laboratories is a noticeably small company, with a market capitalisation of ₹340m. 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 Alpa Laboratories 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. In order to fully understand whether ALPA is a good investment for you, we also need to consider important company-specific fundamentals such as Alpa Laboratories’s financial health and performance track record.
