High Margins, 1.0% Discount: Buy Merck Stock Now
Merck (MRK) stock might be a good buy now. Why? Because you get high margins – reflective of pricing power and cash generation capacity – for a discounted price. Companies like this generate consistent, predictable profits and cash flows, which reduce risk and allow capital to be reinvested. The market tends to reward that.
What Is Happening With MRK
MRK is up 5.8% so far this year, but is actually 1.0% cheaper based on its P/S (Price-to-Sales) ratio compared to 1 year ago.
The stock may not reflect it yet, but here is what’s going well for the company: Recent developments point to a product mix and pricing strategy supporting strong cash generation. Q3 2025 saw increased demand for KEYTRUDA in new indications and early-stage cancers, alongside a rapidly growing uptake of WINREVAIR and CAPVAXIVE. The recent FDA approval for subcutaneous KEYTRUDA is set to expand patient access, further enhancing its market position. These portfolio advancements, combined with careful spending, affirm the company’s margin strength, contributing to positive year-to-date stock performance.

- Long-Term Profitability: About 28.2% operating cash flow margin and 23.7% operating margin last 3-year average.
- Revenue Growth: Merck saw growth of 1.7% LTM and 2.9% last 3-year average, but this is not a growth story
- Available At Discount: At P/S multiple of 3.3, MRK stock is available at a 1.0% discount vs 1 year ago.

Don’t Expect A Slam Dunk, Though
While MRK stock may be a compelling investment opportunity, it’s always helpful to be aware of a stock’s history of drawdown. Merck fell about 38% in the Dot-Com Bubble and took an even bigger hit, 63%, during the Global Financial Crisis. The 2018 correction shaved off 18%, while the Covid sell-off pulled it down roughly 27%. The recent inflation shock knocked around 20% off the peak. So even a solid name like MRK isn’t immune when the market turns sour. Good fundamentals matter, but at times of widespread stress, declines like these are expected.
