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.

Owns shares in the company, and will continue to hold. Very strong R&D department. Lots of excellent patents that have a long runway. Good brand name with consumers. Excellent financial results. Would recommend for the long term investor. 

PAST TOP PICK
(A Top Pick Aug 28/23, Up 7%)

The whole space has lower beta, lower risk. 9% YOY revenue growth, well ahead of estimates. Lots in the pipeline. 15x forward PE, yield is 2%. Risks of competition, but her target is still $140 so lots of upside. Pullback provides great entry point. Analysts say Outperform of almost 25% upside from here.

PARTIAL BUY

Is a huge believer in this, but China is a short-term problem.

PAST TOP PICK
(A Top Pick Aug 23/23, Up 16%)

Sector's low beta makes it immune to economic shocks. YOY revenue growth of 9%. New products in pipeline, promising collaborations, JV with Moderna. FDA-approved hypertension drug has great growth prospects. Forward PE of 15.4x, still attractive. Generous dividend yield of over 2%. Another 12% upside from here.

(Analysts’ price target is $140.00)

Trevor Rose’s Insights - Trevor’s most-liked answers from 5i Research

The pharma sector is always in the political crosshairs. Both candidates have vowed reforms, but in different approaches. But both like to attack drug prices, both in amount and how they are paid (third party insurance, medicare, etc.). In other elections, though, the 'talk' is often worse than what actually happens. Both candidates know the sector is important for US growth, and the population is getting older. MRK and others can best compete with their drug pipeline, so that they can grow even with restrictions on revenue/prices. For MRK in specifically, consensus calls for very strong EPS growth in each of the next two years. If MRK can meet expectations, we think it can overcome any political fallout. It is also quite cheap at 14X earnings so some uncertainty is embedded in prices already.

PAST TOP PICK
(A Top Pick Jun 09/23, Up 21%)

Healthcare was out of favour for a long time, but is starting to enjoy some love. Keytruda, their drug, sells over $25 billion revenues--the most in history--and this patent won't expire until 2028-9, so there's time

BUY

Keytruda keeps working.

WEAK BUY

Chart looks pretty good, trading above 200-day MA. Higher highs and higher lows this year. Pretty good PEG ratio, fairly cheap valuation. Trades at 15x estimated earnings, not bad at all.

Prefers growthier areas, such as weight loss and diabetes, and distributors such as CAH and MCK.

WEAK BUY
MRK vs. LLY

Owns neither. If had to choose, go with MRK based on valuation. Pretty good product pipeline, investing a lot in R&D to keep it strong. Looking to expand operating margins.

BUY

It reports Thursday. He expects them to announce new drug applications, the anti-cancer portfolio and their acquisitions.

BUY

Shares jumped today after getting approval for their pulmonary hypertension drug. This is huge. In 2023, 40% of their sales were from the keytruda drug, but this will go off patent in 2028

BUY

Absolutely a reasonable choice in the sector. Beat numbers last quarter. Lots of cash, ability to buy assets in areas of growth or where they want to add expertise. Increased guidance. Worth owning.

BUY

Better pipeline than PFE. Very strong oncology drug, proving effective in cocktail form against different cancers. This one drug represents over 40% of revenues. Patent on this one runs off around 2027-28, but pipeline is robust.

DON'T BUY

He owns ELI and AZN instead. MRK's key drug, Keytruda, is an anti-cancer treatment which drove their sales up 21% last year, and amounts to nearly 30% for their sales, but the patent cliff will happen in 2028. So, MRK must replace those sales (drug pipeline or buy a company). Be cautious here.

TOP PICK

Portfolio of cancer-fighting stars. Great portfolio and great pipeline. Low valuation of 12x earnings. AAA balance sheet, good future. Good times ahead. Yield is 3%.
