Simply Wall St

Smurfit Westrock (NYSE:SW) has drawn fresh attention from investors after several analysts upgraded the stock, citing renewed optimism around its prospects. These upgrades focus on price stabilization in the containerboard market and the company’s dominant industry position following its recent merger.

Despite a volatile few months for paper and packaging stocks, Smurfit Westrock’s 5.15% one-day share price jump stands out, especially after a sector-wide selloff driven by weak competitor results. While the stock is still down 19% year-to-date, its three-year total shareholder return of 77% points to a much stronger long-term performance. Recent momentum suggests investors are warming to the company’s growth narrative as consolidation and price stabilization trends take hold.

If you’re interested in broadening your investment outlook beyond packaging giants, this could be the perfect time to discover fast growing stocks with high insider ownership.

With analyst upgrades stacking up and price targets rising, the big question now is whether Smurfit Westrock’s shares remain undervalued, or if the recent rally signals that the market has already priced in coming growth.

Most Popular Narrative: 23.6% Undervalued

With Smurfit Westrock closing at $43.30 and the most widely followed narrative pinning its fair value nearly $13 higher, the stock's upside case is on full display. The consensus view stacks future earnings growth and margin recovery against present market skepticism.

Ongoing realization of at least $400 million in identified synergies, with management highlighting a similar or greater opportunity from further commercial and operational improvements, should result in sustained increases in margins and operating leverage, materially boosting future earnings.

Another View: Risks in the Ratios

While fair value estimates point to Smurfit Westrock being undervalued, its current price-to-earnings ratio tells a very different story. Trading at 64.1x, well above both the global packaging sector average of 16.1x and the peer average of 21.4x, the stock looks expensive by this measure. Even the market’s fair ratio estimate sits at 35.6x, signaling possible downside if multiples revert. Are current forecasts justifying this valuation risk, or is the premium a warning sign?
