Check out the companies making headlines midday Wednesday:
FedEx, UPS —Shares of FedEx and UPS fell 1.3 percent and 1.7 percent, respectively, after The Wall Street Journal reported that Amazon is trying to poach shippers from the two companies by offering lower fuel surcharges and fees.
United Technologies — Shares of United Technologies jumped 5.4 percent after the company reported adjusted earnings of $1.95 a share, easily topping an estimate of $1.53. The company's revenue also got a boost from its acquisition of Rockwell Collins.
Procter & Gamble — The company's stock rose 4.9 percent after the release of stronger-than-expected quarterly earnings. Procter & Gamble said its organic sales grew by 4 percent, also surpassing estimates.
Waters Corp. — Shares of the laboratory instrument maker jumped 12.7 percent and posted their best day since April 28, 2009. Waters reported a quarterly profit that topped analyst expectations. Its guidance for the current quarter was also better than expected.
Synchrony Financial — Synchrony Financial shares climbed more than 10 percent after releasing better-than-expected earnings. The company also said it will continue to manage Walmart's Sam's Club credit-card portfolio.
Comcast — Shares of the media giant jumped 5.5 percent after its fourth-quarter results beat estimates. However, the company added fewer-than-expected high-speed internet customers in the previous quarter.
Capital One — Capital one slipped 6.2 percent after releasing its fourth-quarter results. The company said its quarterly revenue came in at $7.01 billion, below an estimate of $7.08 billion.
Dell Technologies — Citigroup initiated coverage of Dell Technologies with a buy rating, citing a "big boost" from the company's debt paydown. Dell shares gained 1.3 percent.
Tesla — The electric car maker's stock dropped 3.8 percent after RBC Capital Markets downgraded the stock to sell. Analysts at the bank said Tesla needs to give clearer long-term guidance. That downgrade pushed the number of sell ratings above the buys among Wall Street analysts.
Restaurant Brands —Shares of Restaurant Brands rose 9.78 percent, as investors cheered a strong preannouncement of the company's quarterly results. Restaurant Brands, which owns Tim Hortons, Burger King and Popeye's, also increased its annual dividend.
