U.S. stock indices finished mixed after a choppy session as investors booked profits in technology and financial stocks, while drugmakers and consumer goods names finished higher.

The

Dow Jones Industrial Average

ended the day up 50.34 points, or 0.6%, at 8469.11, while the

S&P 500

gave back only 0.89 point, or 0.1%, to 908.35. The

Among the biggest decliners,

General Motors

(GM) - Get Report

slid 20.1% to $1.15 after top executives used a window of opportunity to sell off their personal stakes of the automakers, which totaled

more than 200,000 shares

. The stock has not closed below $1.20 since 1933, according to

CNBC

.

Apple

(AAPL) - Get Report

was one of the weakest performers on the Nasdaq, down 4%.

Dish Network

(DISH) - Get Report

retraced some of its gains from Monday's session, while

Liberty Media

Market analysts say that the rally in stocks may have come too far too fast, and that selling in different sectors over the last two sessions should have been expected as investors locked in profits.

"From its crisis low on March 9, the S&P 500 has risen by more than 35% -- a rally whose size and speed leave a dizzy feeling of something too good to last," James Paulsen, chief investment strategist with Wells Capital Management, said in an email.

Paulsen said that the market surge since March could "still fade and simply prove yet another sucker's rally," but he also drew comparisons to a similar market recovery in 1982, adding that "new bull markets often start when 'Main Street' issues still seem overwhelming and bleak."

Art Hogan, chief market strategist with Jefferies, argued that "it's hard to be comfortable with any rally without a little backing and filling. Everyone has been questioning the foundation of the run higher. Intuitively, it makes sense, but it's encouraging that the majority of people are convinced."

The fluctuation in equities Tuesday "makes sense," Hogan said, as we've left the "catalyst-rich environment that included earnings, the jobs report, and the government's stress test results" to a quieter week in terms of earnings and economic news.

Hogan added that even a flat day for equities is "a huge home run."

Before the open, stock futures were indicated higher, but optimism was dampened by Nobel Prize-winning economist Paul Krugman, who told a forum in Shanghai that the swift economic recovery that equities have priced in may not come as quickly as some expect.

"It looks to me now as if the markets are now pricing in a rapid recovery, that they're pricing in a V-shaped recession, which I consider extremely unlikely," Krugman said, according to a

Bloomberg

report. "The market seems to be looking as if this is going to be an average recession, but it's not."

On Monday, the financial and commodity sectors pressured the market in New York. The Dow finished down 155.88 points, or 1.8%, to 8418.77. The S&P 500 slid 19.99 points, or 2.2%, to 909.24, and the Nasdaq dipped 7.76 points, or 0.5%, to 1731.24.

"My concern is that investors are getting a bit complacent about these one-day pullbacks," said Marc Pado, U.S. market strategist with Cantor Fitzgerald, in an email. "As soon as we start to expect it, it will develop into something more."

Traders were also dealing with another round of capital-raising measures, this time headlined by

became the latest bank to announce a common stock offering in order to repay funds borrowed from the Troubled Asset Relief Program. The bank raised $1.2 billion after pricing 42 million shares at $28.75. The dilutive effect pressured shares, which ended down 3.8% to $28.43.

Nissan

(NSANY)

reported a

narrower-than-expected loss for the fiscal year

ended March 31. The automaker lost 233.7 billion yen ($2.4 billion) and said losses will continue as it expects next year to remain "challenging."

In the lone economic report out before Tuesday's open, the trade deficit rose to $27.6 billion in March from $26.1 billion in February. March's read is less than economists' forecasts of $29 billion.

As for Treasuries, the 10-year note was unchanged in price to yield 3.17%, and the 30-year bond gained 14/32 to lower the yield to 4.16%. The dollar fell against the euro and was essentially flat against the yen.
