Stocks finished modestly higher in light-volume trading Friday, with the Nasdaq closing at its best level since November 2000, but gains were limited as investors hesitated to jump in amid a lack of strong catalysts to further fuel the recent rally.
Despite the day's rally, the Dow failed to finish above the widely-watched 14,000 level and also closed lower for the week, snapping five-weeks of consecutive gains.
The Dow Jones Industrial Average gained 48.92 points, or 0.35 percent, to end at 13,992.97, led by Hewlett-Packard and United Health.
The CBOE Volatility Index (VIX), widely considered the best gauge of fear in the market, fell to end near 13.
For the week, the Dow slipped 0.12 percent, the S&P 500 edged up 0.31 percent, and the Nasdaq advanced 0.46 percent. Pfizer was the biggest decliner on the Dow for the week, while UnitedHealth was the best performer.
Among the key S&P sectors, consumer staples was the best weekly performer, while telecoms slipped.
Meanwhile, snow started to fall around the Northeast at the start of what's predicted to be a massive snowstorm of "historic proportion," just a few months after the disruption caused by Superstorm Sandy. The New York Stock Exchange said it will be "business as usual" as the storm approaches.

Home generator maker Generac shares rallied to its highest level since its IPO in February 2010.
"The S&P got above 1,515 and it reached across 1,517 but didn't follow through," said Art Cashin, director of floor operations at UBS Financial Services. "Also, the volume's been light but it got even lighter after Europe closed. So perhaps a lot of this rally, with the storm inhibiting people in the northeast, has been coming out of Europe and maybe that's why we didn't see the follow through."
NYSE total volume is on track for its lowest day since December 25, or about 50 percent lower than the average volume this year of 3.4 billion.

Meanwhile, German data showed a 2012 surplus that was the nation's second highest in more than 60 years.
CIT Group rallied amid a report from Reuters that the bank holding company held preliminary talks over the past 18 months to sell itself to banks including Toronto-Dominion and Wells Fargo, though nothing came of the conversations. However, a CIT spokesman declined to comment.
McDonald's edged higher even after the fast-food giant said January same-store sales around the world dropped 1.9 percent, a steeper decline than analysts expected. McDonald's warned last month that sales would be lower.
Among earnings, LinkedIn surged after the social-networking website blew past earnings expectations and handed in current-quarter revenue guidance that exceeded Wall Street expectations.
Activision Blizzard soared after the videogame publisher topped earnings and revenue expectations and handed in current-quarter guidance that beat estimates.
So far, almost 60 percent of S&P 500 companies have posted quarterly results, with 70 percent of firms topping earnings expectations and 66 percent exceeding revenue estimates, according to Thomson Reuters. If all remaining companies report earnings in line with estimates, earnings will be up 5.2 percent from the fourth quarter of last year.
In Europe, a two-day European Union (EU) summit continued in Brussels, the first since Prime Minister David Cameron confirmed Britain will hold a referendum on EU membership.
