See our latest analysis for Tosoh. The latest guidance upgrade comes as Tosoh’s share price sits at ¥2,443.5. The 30-day share price return is 4.49%, while the 90-day share price return shows a 3.59% decline. Over a 1-year period, the total shareholder return of 25.85% points to momentum that has built over a longer stretch. If you are looking to widen your watchlist beyond chemicals and materials, this is a good moment to check out a curated list of 35 power grid technology and infrastructure stocks as another angle on infrastructure related themes. With Tosoh now guiding to higher earnings and the stock trading at ¥2,443.5, the key question is whether the recent upgrade and 1 year return of 25.85% leave further upside or if the market is already pricing in future growth. ## Preferred P/E of 22.1x: Is it justified? Tosoh trades on a P/E of 22.1x, which sits below the peer average of 39.8x but above both the chemicals industry average of 13.7x and its own estimated fair P/E of 21.5x. The P/E ratio compares the company’s current share price to its earnings per share and is a quick way to see how much investors are paying for each unit of earnings. For a diversified chemicals group with forecast earnings growth and exposure across basic and specialty products, this multiple can reflect how the market weighs growth potential against recent profit volatility and one off items. Here, the P/E being lower than the 39.8x peer average suggests the stock is priced more cautiously than some peers. Earnings are forecast to grow 19.68% per year and faster than the JP market at 10.1% per year. At the same time, the ratio is higher than the JP chemicals industry average of 13.7x and slightly above the estimated fair P/E of 21.5x. This indicates the market is assigning a richer earnings multiple than the level that regression based fair value points to, and that this premium could compress toward that fair level over time. Explore the SWS fair ratio for Tosoh **Result: Price-to-Earnings of 22.1x (OVERVALUED).** However, investors still need to weigh risks such as cyclicality in chemicals demand and any reversal in yen weakness that could squeeze margins and overseas competitiveness. Find out about the key risks to this Tosoh narrative. ## Another View: DCF Points the Other Way While the 22.1x P/E looks slightly rich against Tosoh’s fair ratio of 21.5x, the SWS DCF model tells a different story. On that measure, the stock at ¥2,443.5 sits about 11.5% below an estimated fair value of ¥2,760.3. This raises the question of which signal should receive more attention. Look into how the SWS DCF model arrives at its fair value. 4042 Discounted Cash Flow as at May 2026 Simply Wall St performs a discounted cash flow (DCF) on every stock in the world every day (check out Tosoh for example).
