Five years ago, Suncor Energy $SU shares were trading around $17.26 each. Today, it's closed at $52.97—a solid 207% gain that reflects its position as one of Canada's largest integrated energy companies, producing oil sands, refining, and operating Petro-Canada retail stations. The chart shows a gradual but persistent climb from 2022 lows, with consistent gains through 2024–2025, and a 52-week high of $54.80 showing the stock is near its strongest recent levels.

In straightforward terms, the compound annual growth rate (CAGR) is 25.18%. That's the average yearly increase—calculated by raising the total growth factor to the 1/5 power and subtracting 1. It means growing your money by about 25% each year, on average.

Dollar-cost averaging (DCA) keeps the approach simple and disciplined: Invest $500 every month for five years, totaling $30,000. This buys more shares when prices are lower and fewer when they're higher, helping smooth out the natural ups and downs in energy stocks. Projecting forward at the same historical CAGR, with a monthly growth rate of about 1.89% from $52.97, your position grows steadily.

This projection follows historical performance, which is not a guarantee of future results. Energy stocks like Suncor are influenced by oil prices, geopolitical events, production costs, environmental regulations, and the global transition to lower-carbon energy sources. The current P/E ratio of 16.72 is attractive for a major integrated oil company, and the 3.25% dividend yield provides reliable quarterly income ($0.43 per share). With a $63.21B market cap and a 52-week high of $54.80 already in sight, Suncor offers a combination of growth potential and income stability.

If you're comfortable with energy sector risks and believe in Suncor's long-term ability to execute, DCA lets you participate steadily without trying to time the market. Your consistent $500 monthly investments could build a meaningful position by 2031. Keep the tank full?
