Tim Cook reassures investors
Apple (AAPL) CEO Tim Cook met with Jim Cramer on CNBC. Cook wanted to ensure investors that not only is Apple not dead, but also that it has plenty of innovative ideas in the pipeline.

Pfizer (PFE) shares were up sharply in early trading. The drug giant raised its outlook for the year after delivering a big beat on both its top and bottom lines for the first quarter. Revenue jumped nearly 20% from a year ago driven largely by strong sales of its new treatments for cancer and its acquisition of Hospira. Pfizer walked away from its $160 billion deal to buy Allergan last month after the Treasury Department issued new rules aimed at blocking the deal's tax benefits.

CVS (CVS) reported better-than-expected earnings and revenue for the first quarter. Sales rose 19% from a year ago thanks to strong demand for its specialty pharmacy benefits. The company also provided an upbeat profit outlook for the current quarter.

Yelp (YELP) shares soared following news late Monday that David Einhorn's hedge fund, Greenlight Capital, took a further long position in the business review site.
