NEW YORK (

TheStreet

) -- U.S. stocks closed near their highs of the session Thursday, holding on to sharp gains throughout the day despite recent sessions marked by extreme volatility near the closing bell. Investors appeared to take their cues from global markets, which rose on

China's assurances that it isn't planning to sell European bonds.

The

Dow Jones Industrial Average

gained 285 points, or 2.9%, to finish at 10,259, a day after the blue-chip average closed below the 10,000 mark. The

S&P 500

added 35 points, or 3.3%, to 1103, and the

Nasdaq

went ahead by 82 points, or 3.7%, at 2278.

"It's nice to have an up day and hold it," said Ryan Detrick, senior technical strategist at Schaeffer's Investment Research. "The fact is that we did hold at those lows from February. Unfortunately, the volume has definitely been light, if you're going to be picky, but that makes sense heading into a three-day weekend. It's not perfect, but hopefully we'll see two up days in a row."

Detrick also noted that today's market upswing broke a recent trend. Each Thursday since the precipitous plunge on May 6, also known as the so-called "flash crash," has found the markets experiencing particularly heavy sell-offs.

But consistent strength has eluded the major indices of late, replaced with heavy volatility and uncertainty, as many maintain that the markets remain fragile.

"It's hard to be optimistic about today's gains with so much downward pressure from recent events," said Bob Enck, chief executive of Equinox Fund Management, earlier in the day.

"The situation in Europe is not going away any time soon. This will be around, and it will be an impactful event for a long time to come," he said, adding, "The unemployment rate in the U.S. is still quite high and until that changes, it's still going to have this dampening effect on the U.S. economy. Add to that, continued uncertainty out of Washington concerning the financial reform bill -- not to mention that you're still hearing about the flash crash, which really spooked individual investors. It all makes for a very volatile trading environment. Until you get some of these larger issues resolved, it's going to be very difficult for equities to have a steady path."

Overseas, Hong Kong's Hang Seng rose 1.2%, and Japan's Nikkei jumped 1.2%. The FTSE in London soared 3.1% higher, as did the DAX in Frankfurt.

The Energy Information Administration said

natural gas storage levels added 104 billion cubic feet in the week ended May 21, which was larger than the projected injection range of 98 billion cubic feet to 102 billion cubic feet, according to a Platts survey.
