If you're interested in Debao Property Development Ltd. (SGX:BTF), 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. 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 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. 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. 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.

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

With a market capitalisation of S$10m, Debao Property Development is a very small company by global standards. It is quite likely to be unknown to 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 Debao Property Development 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.
