If you're interested in PW Medtech Group Limited (HKG:1358), then you might want to consider its beta (a measure of share price volatility) in order to understand how the stock could impact your portfolio. Modern finance theory considers volatility to be a measure of risk, and there are two main types of price volatility. 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 type is the broader market volatility, which you cannot diversify away, since it arises from macroeconomic factors which directly affects all the 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. A stock with a beta below one is either less volatile than the market, or more volatile but not corellated with the overall market. In comparison a stock with a beta of over one tends to be move in a similar direction to the market in the long term, but with greater changes in price.

Could 1358's size cause it to be more volatile?
PW Medtech Group is a rather small company. It has a market capitalisation of HK$1.9b, which means it is probably under the radar of most investors. It takes less money to influence the share price of a very small company. This may explain the excess volatility implied by this beta value.
What this means for you:
Beta only tells us that the PW Medtech Group share price is sensitive to broader market movements. This could indicate that it is a high growth company, or is heavily influenced by sentiment because it is speculative. Alternatively, it could have operating leverage in its business model.
