Starbucks A third and final stock that would make for a really smart buy with $300 in May is brand-name coffee chain Starbucks (NASDAQ: SBUX). While both of these worries have played key roles in weighing down Pinterest's valuation, I don't foresee either having any effect on the company's long-term growth trajectory or strategy. But over the past couple of months, the Federal Reserve has signaled its intent to be aggressive with interest-rate hikes to control inflation.
