Stocks fell again today but were unable to come off their lows like yesterday. Concerns over Trump's foreign policy, and tough talk on North Korea have investors cautious going forward. The Dow 30 lost 64, the S&P 500 fell 9, and the Nasdaq 100 sold off 30. As we move into the later part of the week the focus seems to continue to be on global issues and less about economic numbers or general market indicators.

Delta Air Lines (DAL  ) shares started the day sharply higher after the airline announced earnings that were better than Wall Street analyst estimates. It wasn't all positive through as revenue missed estimates and profit fell from a year ago. This caused traders to sell the open which pushed Delta lower all day long. The company also said it expects "passenger revenue per available seat mile to turn positive this quarter." Shares are still lower on the year though technical traders have been looking at the $44 area for support.

BlackBerry (BBRY  ) blasted off today after the Canadian tech company revealed a legal win against Qualcomm (QCOM  ). The results of the case show that Qualcomm will have to pay BlackBerry about $815 million in a preliminary arbitration decision over royalty, over payments. A final award, including interest and attorney fees, will be issued after a hearing at the end of May. Shares moved to new highs on the year and are now higher by almost 30% in just a few weeks.

Whole Foods Market (WFM  ) added another 2% today as a report showed that there may have been more than one interested buyer for the organic grocery chain. Bloomberg reported late Wednesday that Amazon (AMZN  ) was considering buying Whole Foods last fall, but nothing came of it at the time. Shares have been on quite the run lately, adding almost 20% in 12 trading days.
