Dow Hits Record; Internet Names Advance

(Reuters) - Stocks rallied on Monday, with the Dow hitting a record high and the S&P 500within striking distance of its own record, while shares of Internet and biotech shares jumped.

Internet and biotech names were among the strongest advancers of the day. Biogen Idec (BIIB.O) gained 4.7 percent to $300.12 while TripAdvisor Inc (TRIP.O) shot up 6.4 percent to $90.02.

Both groups - often described as "momentum" stocks due to massive gains in recent months - have been wildly volatile in recent sessions, moving on concerns over valuation and hopes for high levels of growth.

The day's advance was broad, with S&P cyclical sector indexes such as materials .SPLRCM, industrials .SPLRCI and consumer discretionary .SPLRCD all up more than 1 percent.

The rally came despite a vote by pro-Russian rebels in favor of self-rule in eastern regions of the country in a referendum dismissed by Kiev and Western governments as illegal. The European Union is set to step up pressure on Russia by taking steps to extend sanctions to companies, as well as individuals.

"The vote seemed like a negative, but the violence that many thought would happen didn't, and at this point, no news is good news when it comes to Ukraine," said Channing Smith, co-portfolio manager of the Capital Advisors Growth Fund at Capital Advisors in Tulsa, Oklahoma.

The Dow Jones industrial average .DJI rose 113.43 points or 0.68 percent, to 16,696.77, theS&P 500 .SPX gained 17.29 points or 0.92 percent, to 1,895.77 and the Nasdaq Composite .IXIC added 70.61 points or 1.73 percent, to 4,142.482.

The Russell 2000 .TOY index of small-cap stocks climbed 2.5 percent. Last week, it flirted with correction territory, dropping nearly 10 percent from its all-time closing high.

Hillshire Brands Co (HSH.N) agreed to buy Pinnacle Foods Inc (PF.N) in a deal valued at about $6.6 billion, including debt. Pinnacle jumped 12.3 percent to $34.20 while Hillshire fell 4.9 percent to $35.14.
