Five years ago, Power Solutions International $PSIX shares were trading around $3.15 each. Today, it's closed at $62.47—a massive 1,793% leap that comes from its focus on alternative-fuel engines, generators, and power systems for industrial, energy, and off-road uses. The chart shows a long quiet period through 2023, then a sharp rise in 2025 as demand for cleaner power solutions kicked in, with after-hours at $62.64. That 52-week high of $121.47 marks the peak strength so far.

To put it simply, the compound annual growth rate (CAGR) is 82.24%. That's the average yearly push—calculated by raising the total growth factor to the 1/5 power and subtracting 1. It means nearly doubling your money each year, on average.

Dollar-cost averaging (DCA) keeps it steady: Invest $500 every month for five years, totaling $30,000. This buys more shares on dips and fewer on peaks, which helps through the quiet and busy times. Projecting forward at the same historical pace, with a monthly growth rate of about 5.31% from $62.47, your shares add up over time.

After 60 months, your total could reach $196,442. That's a gain of $166,442—a 554% return on your investment. The early buys get the biggest compounding boost, while later ones still ride the wave.

This is based on the past, which isn't a sure thing ahead—industrial engine stocks can swing with energy trends or regulations, but a P/E ratio of 11.89 shows reasonable pricing, and a $1.44B market cap gives room to grow.

With that 52-week high of $121.47 as a recent top, PSIX has spark. If DCA matches your steady style, it could turn your $500 habit into a charged payoff by 2030.
