Merck Shares Climb 0.84% Amid 74.33% Volume Spike Ranks 62nd in Market Activity as FDA Grants Breakthrough Status to ADC Candidate

On August 19, 2025, Merck (MRK) traded at a volume of 1.22 billion shares, a 74.33% increase from the prior day, ranking 62nd in market activity. The stock closed 0.84% higher, reflecting mixed signals from its operational and strategic updates.

The FDA granted Merck’s ADC candidate Breakthrough Therapy designation, signaling regulatory momentum for its oncology pipeline. This development follows a broader industry trend toward immunotherapy advancements, with Merck competing against peers like Roche and Pfizer in high-growth therapeutic areas. The move could bolster investor confidence in its long-term pipeline despite near-term challenges.

Merck revised its 2025 sales guidance to $64.3–$65.3 billion, citing foreign exchange headwinds and weaker-than-expected Q2 performance. The company also announced a $3 billion annual cost-cutting initiative by 2027, including workforce reductions and investment refocusing. Analysts noted the measures aim to mitigate risks ahead of Keytruda’s patent expiration in 2028, though the strategy’s long-term value creation remains under scrutiny.

Collaborative efforts with Veeva Systems to adopt Vault CRM underscore Merck’s digital transformation push. The partnership, highlighted by Oppenheimer analysts, reflects broader pharma industry shifts toward technology integration for operational efficiency. Meanwhile, regulatory pressures, including President Trump’s demand for lower drug prices, persist as a tailwind for cost-conscious strategies.

Backtested data from 2022 to 2025 shows a strategy of holding top-volume stocks for one day yielded a 7.61% total return, with a Sharpe ratio of 0.94. However, the approach faced a -29.16% maximum drawdown, underscoring market volatility risks during downturns.
