ATHENS, Feb 1 (Reuters) - Greek bank shares .FTATBNK jumped more than 8 percent on Tuesday as bond yield spreads tightened below 800 basis points and traders anticipated positive news from an upcoming EU summit on the debt crisis. “Spreads are down, below 800 bps, ahead of an EU summit later this week where traders expect positive developments on the debt crisis. There is also short-covering,” said investment adviser Theodore Mouratidis at Fortius Securities.
The bourse's banking index hit a three-month intraday high, outperforming the broader Greek market .ATG which was gaining 4.3 percent.

The yield on 10-year Greek government paper GR10YT=RR over bunds tightened to 796 basis points from 820 earlier in the day.
“Bank shares had been pounded as investors discounted restructuring with haircuts,” another trader said.
Adding to improved sentiment, Credit Suisse upgraded Greek equities to “benchmark” from “underweight”, citing cheap equity valuations and a range of supportive macroeconomic factors. (Reporting by George Georgiopoulos; Editing by Jon Loades-Carter)
