| The Dow has risen for seven straight sessions, 
				the longest streak for the blue-chip index since March 2013, 
				while the S&P 500 is up 5.9 percent over the past seven 
				sessions, ending at its 52nd record close of the year on Friday.
 The speed and scale of the rally could make further gains 
				difficult to come by, especially in the final trading week of 
				the year, when many market participants are out on holiday and 
				there are few trading catalysts. Trading volume is expected to 
				remain light, which could leave the market more susceptible to 
				big swings.
 
 Biotech stocks were among the biggest movers of the premarket 
				session. Gilead Sciences <GILD.O> rose 2.1 percent to $95.75 
				before the bell after Morgan Stanley upgraded the stock to 
				"overweight" from "equal-weight." Juno Therapeutics <JUNO.O> 
				rose 7.5 percent to $52.37 after the company, in an 8-K filing, 
				authorized a stock buyback program of 495 million shares.
 
 Energy shares will continue to be in focus as crude oil <CLc1> 
				rose 1.3 percent to $55.41 on concerns about disruption to 
				exports from Libya.
 
 Oil has dropped in 12 of the past 13 weeks, weighing on the S&P 
				energy index <.SPNY>, which is by far the weakest sector of the 
				year, down 9 percent.
 
 Indexes are on track to close out a third straight positive 
				month. Thus far in December, the Dow is up 1.3 percent, the S&P 
				is up 1 percent and the Nasdaq is up 0.3 percent. In the fourth 
				quarter, the Dow is up 5.9 percent, the S&P is up 5.9 percent 
				and the Nasdaq is up 7 percent. Both the S&P and Nasdaq are on 
				track for their eighth straight quarterly gain, the longest for 
				the S&P since 1998 and the longest for the Nasdaq since 1996.
 
 In 2014, the Dow is up 8.9 percent in its sixth straight yearly 
				gain, the S&P is up 13 percent and the Nasdaq is up 15 percent. 
				Recent gains this year were fueled by strong economic data, 
				including a bullish read on economic growth last week, as well 
				as accommodative measures from central banks.
