Charles River Laboratories International, Inc. (CRL) gained 6.10% on September 25, 2026, bringing its share price to $294.37. The move extended the stock's seven-day advance to 4.51%, reflecting sustained buying pressure over the recent trading week.
Despite the short-term strength, CRL remains down 1.07% over the trailing 30-day period, suggesting the session's gains have not yet fully recovered ground lost earlier in the month. The company's market capitalization stood at $13.24 billion as of the close.
The single-day move of 6.10% was notable in magnitude, representing one of the more significant daily percentage swings for a company of CRL's size. Whether the momentum carries forward will depend on broader market conditions and developments specific to the contract research organization sector.
