Johnson & Johnson (NYSE: JNJ), a major component of healthcare sector exchange traded funds, will enjoy greater sales of its specialized drugs.

“Based on second-quarter-to-date IMS data, we see the potential for outperformance from several of Johnson & Johnson’s key U.S. drugs–including Invokana/Invokamet [type 2 diabetes], Xarelto [blood thinner], Invega Sustenna [schizophrenia]and Remicade [Crohn’s disease and others]–that in aggregate could deliver some modest upside in the quarter, although we expect this strength to be largely offset by weaker-than-expected Olysio [chronic hepatitis C]sales,” according to Wells Fargo analysts.

Consequently, Wells Fargo has placed an outperform rating on the pharmaceuticals giant.

Johnson & Johnson’s outlook bodes well for the healthcare sector as the company stock is a major component in both healthcare and pharmaceutical sector ETFs.

For instance, the Health Care Select Sector SPDR (NYSEArca: XLV) includes a 9.6% tilt toward JNJ while iShares U.S. Healthcare ETF (NYSEArca: IYH) holds a 9.1% position in JNJ. The pharmaceuticals sub-sector makes up 42.5% of XLV and 40.6% of IYH.

Additionally, JNJ is 9.3% of iShares U.S. Pharmaceuticals ETF (NYSEArca: IHE) and 8.2% of Market Vectors Pharmaceutical ETF (NYSEArca: PPH).

Supporting the pharma space, recent Nielsen data revealed in-line or better performance in the U.S. consumer segment. Additionally, currency risk has diminished after the euro improved marginally against the USD since mid-April while the yen only depreciated modestly. The analysts calculate that for the full year, net exchange-rate impact worsened by less than $10 million.

“With marginally worse incremental exchange-rate headwind, we believe these strong underlying overall trends in the U.S. Pharmaceuticals and Consumer businesses to bode well for Johnson & Johnson’s second-quarter results and remainder-of-2015 outlook,” Wells Fargo added.

Later this year, J&J plans to file for approval for the experimental drug daratumumab for multiple myeloma, a type of blood cancer, in the U.S. and Europe. Wells Fargo analyst Larry Biegelsen projects daratumumab sales could hit $1.3 billion by 2019. [Innovators to Support Healthcare Sector, ETFs’ Growth]

The shift into research and development comes at a time as big pharmaceutical names brace for large drug patent expirations. Looking ahead, industry growth will be propelled by a slew of niche or specialized drugs with a targeted application for specific diseases.

“From an innovation standpoint, drug companies are focusing most on specialty care,” according to Morningstar analyst Robert Goldsborough. “As a result, pharmaceutical and biotech firms are targeting smaller patient populations, particularly in oncology, virology, and immunology. Innovating in areas of previously-unmet needs should offer higher odds of approval by U.S. regulators and better pricing power for drug firms.”
