Index removals put Repligen in focus

Repligen (RGEN) has drawn fresh attention after being dropped from multiple Russell growth and small cap benchmarks, a shift that raises questions about how index changes and existing business pressures intersect for the stock.

Repligen’s recent index removals come after a mixed run in the stock, with a 1 month share price return of 10.61% and a 90 day share price return of 19.85%. However, the year to date share price has declined 12.42%, while the 1 year total shareholder return is 7.42% and the 5 year total shareholder return is down 26.97%. This suggests that near term momentum has picked up even as longer term returns remain under pressure.

Another View on Repligen’s valuation
