Dollar-cost averaging (DCA) keeps it grounded: Invest $500 every month for five years, totaling $30,000. This buys more shares on dips and fewer on peaks, which helps through coal market swings. Projecting forward at the same historical pace, with a monthly growth rate of about 4.79% from $203.06, your shares build value over time.

After 60 months, your total could reach $171,998. That's a gain of $141,998—a 473% return on your investment. The early buys get the biggest compounding lift, while later ones still tap into the vein.

This is based on the past, which isn't a guarantee ahead—coal stocks can fluctuate with steel demand, energy transitions, or regulations, but no P/E ratio listed focuses on growth, and a $2.61B market cap gives room to expand.

With that 52-week high of $215.30 in view, AMR has solid reserves. If DCA's your steady drill, it could turn your $500 habit into a rich find by 2031.
