Even with a solid revenue beat and a new quarterly dividend just announced, Smurfit Westrock’s recent results have not eased investor concerns. Its share price has dropped 31% year-to-date, while the one-year total shareholder return stands at -26%. That said, over the past three years, the stock has still managed a total shareholder return of 22%, reflecting longer-term value for those able to stomach short-term volatility.
