Those exploration wins and the recent $300 million convertible notes issue have landed in a market that was already warming to the story. A 30 day share price return of 31.02 percent and a year to date share price return of 157.16 percent point to strong positive momentum, while the 1 year total shareholder return of 163.72 percent and 3 year total shareholder return of 88.5 percent underline how sentiment has steadily swung in First Majestic’s favor as investors price in higher growth and, arguably, a healthier balance between risk and reward.

If Santa Elena’s expansion has you rethinking where the next leg of growth could come from, it is worth exploring fast growing stocks with high insider ownership as a way to uncover more ambitious, owner aligned ideas beyond precious metals.

With Santa Elena’s potential ramping up, a fresh $300 million in low cost capital, and the shares still trading well below some intrinsic value estimates, is this a genuine buying opportunity or has the market already priced in future growth?
