What happened

Investors in the Swiss pharma giant Novartis (NVS 1.09%) had a rough 2016. The company's stock swooned by more than 15% during the year, according to data from S&P Global Market Intelligence. That return vastly underperformed the healthcare sector in general, as measured by the Vanguard Health Care ETF (VHT 0.73%).

So what

The company's waning share price can be placed squarely on the shoulders of its lackluster financial performance. Novartis' top line was under pressure all year due to the loss of patent protection on a handful of key drugs. In 2015, generic competition moved in on the company's lucrative Diovan franchise. Last year's victim was the blood cancer drug Gleevec, which was the company's top-selling drug. The weakness in these two franchises caused total sales to drop by 1% in the most recent quarter, which led to a 3% dip in earnings per share. While those figures are not horrendous given the circumstances, they won't get investors excited, either.

Thankfully, Novartis does have a number of newly launched drugs that are helping offset the declines in its legacy sales. The company's autoimmune disease drug Cosentyx is rapidly taking market share away from AbbVie's Humira and Amgen's Enbrel. With peak annual sales estimates of up to $5 billion, this drug could go a long way toward offsetting the declining sales in Gleevec.

Entresto is another drug that promises to fill the sales void. This heart-failure drug was clinically proven to reduce the risk of death from cardiovascular causes by 20%. While reimbursement issues have caused sales to be a bit sluggish out of the gate, some market watchers believe that this drug could ultimately produce peak sales of $10 billion.

Of course, not every market watcher is a believer in Enrtresto's potential. Earlier this year, an analyst at Leerink released some research that showed Entresto's high cost is going to prohibit rapid adoption. As a result, the analyst stated that peak sales estimates for the drug are vastly overstated, which, if true, could be a real bummer for investors.

Now what

Novartis' current product portfolio should allow the company to post EPS growth of more than 4% over the next five years. While that's not an eye-popping figure, it is a decent number for a company of this size. What's more, when you combine that growth rate with the company's market-beating yield of 3.7%, there are reasons to believe that buying shares today offers a good chance at achieving an attractive total return.

Overall, if you're looking for a reliable stock that offers income, value, and modest growth prospects, you could do worse then picking Novartis.
