Atlanta Federal Reserve President, Dennis Lockhart, expressed concern that the recovery is so weak that the big D -- deflation, or a dangerous drop in price levels, is a risk that warrants watching. He added that deflation discussion will likely be on the next Fed agenda. He said: "It's appropriate to think about what we would do under a deflationary scenario." He is more convinced than ever that short term interest rates remain at record lows.

Fed board governor Elizabeth Duke said that full restoration of credit growth is likely to be years away.

The second half of the calendar year has begun, and earnings return to the spotlight this week. As usual, Alcoa Inc. (NYSE: AA) is among the first of the S&P 500 to report quarterly results. For the second quarter in which Alcoa agreed to sell its wire harness and electrical distribution business and its fastening systems business expanded into Morocco, analysts surveyed by Thomson Reuters expect the New York-based aluminum producer to report swinging to a net loss of $0.34 per share from a profit of $0.66 per share in the year-ago period. Second quarter revenue is expected to have fallen 48.3% to $3.9 billion. The full-year forecast is currently for a loss of $1.04 per share and revenue of $16.7 billion (-38.0%). Alcoa has missed expectations in the past three quarters, by as much as 17 cents per share. The long-term EPS growth forecast is 10.0%, which is better than the sector average. Alcoa slashed its dividend earlier this year, and the First Call consensus recommendation remains to hold AA. However, TheStreet.com recommends it as an against-the-grain pick. At $9.86, shares are down 12.4% since the beginning of the year, and recently have been bumping up against the 200-day moving average.
