Eli Lilly ( LLY -6.59%) is the most valuable healthcare stock in the world, with a market capitalization of around $720 billion. For a while, it looked like it might be on track to be the first healthcare company to top a $1 trillion valuation, perhaps as early as this year.

Eli Lilly’s expectations for sales in the fourth quarter of last year missed forecasts, driven by lower-than-expected sales of its diabetes and obesity drugs.

The S&P 500 added 0.1% on Tuesday, Jan. 14, as tame wholesale inflation data provided a positive signal ahead of Wednesday's consumer price report.
