One myth about investing in the stock market or any other market where prices fluctuate is that it’s risky. But people who know how to value a stock understand that it doesn’t have to be risky if they buy the right stocks at the right time. Volatility and risk aren’t always correlated. Some companies with steady growth such as Enbridge have been pretty stable over the years.

That’s not to say ENB is a good buy today because whether a stock is reasonably valued or not is another topic. But here’s a look now at Caterpillar below, who manufactures construction equipment, heavy machinery, etc.. Notice how the stock is more volatile over the same period as Enbridge.

But that doesn’t necessarily mean CAT is a riskier stock than ENB.  CAT is a more cyclical company so its Beta is suppose to be higher. What makes a company safe to invest in for myself is a positive trend of earnings growth, dividend growth, and industry expansion. Both companies have had stable dividend growth over the last decade meaning managers are confident about their company’s future performance. Both companies have also increased their profits over the years. Pipeline companies are looking to expand their pipes across Canada, and In Alberta alone the government has forecast there will be 114,000 jobs in the construction industry over the next decade (o.O) ENB and CAT are both in growing industries with growing demand for their products/services.  Stocks can vary in risk depending on what kind of business they are, but volatility doesn’t necessarily mean risk. It just means at some point in time, there might be  a good opportunity to buy the stock at a great value ;)

Here’s what the Oracle had to say on the subject….

“Volatility does not measure risk. Past volatility is not a measure of risk. It’s nice math, but it’s wrong. If a farm in Nebraska used to sell for $2,000 per acre, and now it sells for $600 per acre, investment theory would say that the beta of farms has gone up, and than they are more risky than before. If you tell that to people, they’ll say that that’s crazy. But farms don’t trade daily the way stocks do. Since stock prices jiggle around, finance professors have translated that into these investment theories. It can be risky to be in some businesses. Risk is not knowing what you’re doing. If you know who you’re dealing with, and know the price you should pay, then you’re not dealing with a lot of risk. We have invested in a lot of sectors that have high betas. The development of beta has been useful to people who want careers in teaching.”
- Warren Buffett

Beta – The measure of volatility. Higher beta = bigger fluctuations in price. The overall market has a Beta of 1. If a stock is said to have a Beta of 1.5 then that means it will be 50% more volatile than the market.
