So who wasn't invited to the party?
Shares of IBM (NYSE:IBM) are down 0.3% today. The company launched a new server line this morning that's priced just below $6,000. The company said it wants to take on Hewlett-Packard, Oracle, and other competitors by offering a more affordable server and Power Systems unit. IBM is attempting to attract the small to medium-sized business with this lower-priced product. Investors may be selling off shares due to fear that the low-price-point servers will ultimately hurt the brand. Additionally, future clients may decide to trade down to the cheaper products, rather than purchasing top-of-the-line units, which will likely hurt margins.

Shares of United Technologies (NYSE:UTX) are also trading lower today, down about 0.3%. It was announced this morning that the company and the Pentagon finally came to an agreement for the next patch of F-35 fighter engines. United Technologies' Pratt & Whitney unit will supply 32 engines, support, and spare parts. The Pentagon did not disclose what the purchase price was, but Lieutenant General Chris Bogdan, the F-35 program executive officer, said, "Engine prices have decreased, and I appreciate everyone’s commitment to drive cost out of the program." Shares are likely lower because of the belief that the engines were sold at a lower price than the market had previously expected.
