If you own shares in Thermal Energy International Inc. (CVE:TMG) then it's worth thinking about how it contributes to the volatility of your portfolio, overall. In finance, Beta is a measure of volatility. 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 are more sensitive to general market forces than others. 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 TMG's beta value
Given that it has a beta of 1.13, we can surmise that the Thermal Energy International share price has been fairly sensitive to market volatility (over the last 5 years). If this beta value holds true in the future, Thermal Energy International shares are likely to rise more than the market when the market is going up, but fall faster when the market is going down. 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 Thermal Energy International fares in that regard, below.
Does TMG's size influence the expected beta?
With a market capitalisation of CA$11m, Thermal Energy International is a very small company by global standards. It is quite likely to be unknown to most investors. Relatively few investors can influence the price of a smaller company, compared to a large company. This could explain the high beta value, in this case.
