NEW YORK (TheStreet) -- U.S. stocks began the week flirting with intraday highs after closing Friday with new records. The weekend didn't dampen any of the goodwill fostered on global markets last week. Instead, overseas indices extended their rally into this holiday-shortened week.
"The seasonality has a bullish tilt," Raymond James' chief investment strategist Jeffrey D. Saut wrote in a note. "I have learned the hard way that it is difficult to sell stocks off during the ebullient period between Thanksgiving and Christmas ... Thanksgiving week also has a bullish bias with a gain for the week of +0.64% two-thirds of the time."
By midmorning on Monday, the S&P 500 was up 0.25% and the Dow Jones Industrial Average climbed 0.13%. The Nasdaq gained 0.58%.
