Bill Gross weighs in
Are the Fed's low interest rate policies harmful to the U.S.? Bond investor Bill Gross thinks so...and in his latest investment letter he writes that now our central bank is starting to think so, too. He writes, because of low interest rates "corporations have borrowed hundreds of billions of dollars, but instead of deploying the funds into the real economy, they have used the proceeds for stock buybacks." Gross adds that the Fed recognizes its policies aren't helping the global economy and will likely hike rates in September.

Oil prices
Major oil companies are feeling the strain of low oil prices. Shell (RDS-A) announced it is cutting over six thousand jobs, while Chevron (CVX) plans to cut over one thousand employees. Meanwhile, some smaller oil producers are faring better than than their larger counterparts. Companies such as Cimarex (XEC) and Cabot Oil and Gas (COG) have outperformed big oil producers.

Whole Foods' slide
The grocery business is notoriously a low-margin one. It's been made even harder for Whole Foods (WFM) as competitors like Walmart (WMT) enter the organic market space. Now the Austin-based supermarket says allegations that it overcharges have hurt sales. The stock was down as much as 12-percent today and more than 28-percent so far this year.
