This summary was created by AI, based on 25 opinions in the last 12 months.

Merck & Company (MRK) remains a focal point in the pharmaceutical sector, particularly due to its leading cancer treatment drug, Keytruda, which accounts for a significant portion of its revenue but faces a patent expiration in 2028. Experts note that while revenue growth has been modest in the past few years, recent breakthroughs in cancer trials have generated optimism for the company's potential future. There is a general recognition of Merck's strong pipeline of upcoming drugs, which could help offset the revenue decline anticipated from Keytruda going off-patent. Several experts have recommended strict stop-loss strategies to protect investments while pursuing gains, emphasizing a balance of growth potential and valuation concerns. Overall, the sentiment leans towards cautious optimism as analysts grapple with Merck's future amidst challenges and opportunities.

BUY

A good drug pipeline with many promising drugs in phase 2 trials, though they have to overcome the patent cliff of Keytruda.

PAST TOP PICK
(A Top Pick Jan 09/25, Up 11%)

They have a good pipeline that will help offset the loss of their major Keytruda drug when it goes off-patent. MRK is good at buying and tucking in companies. Their 2025 chart wasn't that great until the end of the year when the sector caught a bid.

BUY

Is bullish healthcare for 2026 because of its growing customer base (baby boomers) who will need health services. He's been adding to Merck, post-Keytruda.

Our PAST TOP PICK with MRK is progressing well.  To remain disciplined, we recommend trailing up the stop (from $70) to $79 at this time.  

DON'T BUY

So many in the space look inexpensive on PE. These businesses are mature, with weaker product pipelines, but generate significant cash. Flipside is that they don't grow. Costs have really risen for all the FDA approval phases, making drug development so much harder.

True, Canadians have to go to the US for healthcare exposure. But he'd prefer ABT, ALC, or BSX for their better growth profiles.

HOLD

Healthcare in US has had one of its worst performances over 10 years. Most sector $$ has gone to obesity drug makers. Two key drugs, more in the pipeline. Quality company. Very cheap, so he'd look at it. Based in New Jersey, so very little tariff impact. Dividend yield over 4%.

DON'T BUY

Culprit for stock pain is Keytruda, coming off patent, and providing 40% of revenues. Slashing costs. Pretty darn cheap down here at 8x for 2027. But no growth rate after Keytruda. Better places in pharma to park capital.

TOP PICK
Stockchase Research Editor: Michael O'Reilly

MRK has taken a tumble as their long standing cancer drug approaches patent expiry in the next few years, leading some analysts to discount their valuation.  It now trades at 13x earnings, 4x book and supports a 35% ROE.  The yield is supported by a payout ratio under 50% of cash flow.  The company is prudently using some cash reserves to retire debt and buy back shares.  We recommend setting a stop-loss at $70, looing to achieve $102 -- upside potential of 19%.  Yield 3.6%  

(Analysts’ price target is $102.19)
BUY

Whole sector's been problematic, so this name could be just caught up in that downdraft. Fundamentally looks pretty good. Could be an opportunity. ROC last few years has been 7%, 9%, 9%, 10%, 11%. Nothing wrong with those numbers. Pretty clean balance sheet, decent working capital position.

Revenue growth last quarter down 1.6%. Before that, it usually ran around a positive 6-7%. Yield is 3.9%, chart looks great as they keep bumping it up once a year -- cashflow and payout ratio to support that look really healthy.

PAST TOP PICK
(A Top Pick Jan 27/25, Down 16%)

Bought is heavily this morning. Is a diversified, large-cap pharma with 45% of revenue is oncology. Keytruda goes off patent in 2028, so there's a race to offset that patent. Vaccines face issues--Gardisil isn't performing in China, and RFK Jr. is anti-vaccines. However, if they combine an enzyme with a drug like Keytruda, does that reset the patent? Does the patent continue? That is in debate.

BUY

Pharmas have not done well. MRK trades at 8x PE. They have one large drug, Keytruda, which makes up 46% of their revenues, which is risky. The chart looks terrible. But MRK has dozens of drugs in phase 2 and 3 trials. Also, this pays a fine dividend. Now is a fine time to enter this.

WEAK BUY

Keytruda is now a decade old, and a lot more competition has come on. Great company. You could probably buy here, but see his Top Picks.

HOLD

Whole healthcare complex was weak in 2023 and 2024, so the valuations were reasonable coming into 2025. Current market downtrend plus today's threat of tariffs on pharmaceuticals, and we don't know how this will all end. Drug pipeline is particularly exciting.

Can't tell you when it will turn the corner, but it's a good component of a diversified portfolio.
