Investing in AI stocks carries the same risk as digging for gold. You might strike it rich, or you might bust. But the one who sells shovels is guaranteed to make money. Rather than buying a direct AI stock, I bought this supplier instead. And because nobody is talking about this company yet, it remains an undervalued hidden gem with an incredible growth potential. That means Hudson Technologies (HDSN stock) is both a value stock and a growth stock. And it’s also an artificial intelligence stock. For all of those reasons, HDSN is one of the best stocks to buy now.
