Meta Platforms (META -1.19%) is one of the most dominant companies on the face of the planet. This "Magnificent Seven" stock has been a huge winner, more than tripling in the past five years. But can Meta shares turn a $10,000 investment into $50,000 by 2030? Should you buy Meta stock now? While Meta won't climb five-fold by the end of the decade, turning $10,000 into $50,000, it still looks like a smart investment.
