Updated from 10:45 a.m. EDTShipping stocks were rising Thursday amid a bit of good news from the dry bulk sector. Diana Shipping ( DXS) announced a long-term time charter contract for the m/v Danae, one of its Panamax dry bulk carriers. The contract calls for a daily rate of $12,000 per day for about 22 to 24 months. Diana shares were up 9.7% to $12.87 in recent trading. A day after Excel Maritime ( EXM) announced it had restructured its loans and would receive a $45 million equity infusion, Jeffries lowered its full-year estimate to $3.73 per share from $5.86 per share and also lowered the target to $8 from $18. Although the equity infusion enhances Excel's liquidity, Jeffries said, the dilution is much greater than expected. Excel Maritime shares were recently up 12.9% to $5.35.
