Nippon Shinyaku (TSE:4516) was removed from the FTSE All-World Index (USD) on 19 September 2026, an event that can trigger forced trades as passive funds rebalance and reassess exposure.
Over the past year, Nippon Shinyaku has combined a 1-year total shareholder return of 9.37% with a sharp year to date share price decline of 36.81%. That weaker recent momentum, including a 15.12% fall over 90 days, helps frame the index removal as part of a broader cooling in sentiment rather than a sudden break in the story.

Nippon Shinyaku’s removal from the index and the sharp share price slide leave a tight gap between market price and analyst targets. Does fair value really cluster here, or do other estimates point elsewhere?
Price-to-Earnings of 7.5x: Is it justified?
Nippon Shinyaku now trades on a P/E of 7.5x, which sits well below both the wider JP market on 13.9x and the JP Pharmaceuticals industry on 14.1x. That gap indicates the market is pricing the shares more cautiously than peers despite a long history on the exchange and a ¥3,497 last close.
The P/E ratio compares Nippon Shinyaku's current share price to its earnings per share. For a pharmaceutical group with ¥157,577 in Pharmaceuticals revenue and ¥31,559 in net income, this multiple is a quick shorthand for how much investors are willing to pay for each unit of profit today.
On the numbers provided, the stock is described as trading at "good value" versus peers on 16x and also versus the broader JP market. The estimated fair P/E of 7.6x sits very close to the current 7.5x, which suggests the market is already near the level that regression-based analysis indicates it could move towards rather than implying an extreme mispricing.
Compared with the JP Pharmaceuticals average on 14.1x, Nippon Shinyaku carries a far lower earnings multiple, which is a strong relative discount. That is tempered by forecasts that point to earnings and revenue declining over the next 3 years, so the lower P/E can be read as the market assigning a more cautious outlook rather than paying up for future growth.

Result: Price-to-Earnings of 7.5x (UNDERVALUED)
Still, the annual declines in revenue and net income, together with the long 3 year and 5 year total return drawdowns, can easily keep skepticism in play.
