As investors get rolling Monday after the three-day weekend, the Dow Jones Industrial Average and the S&P 500 stand in record territory on the first day of the second quarter, after managing small gains in last week's up-and-down trading.
But 2012 high-flyer Apple—whose 31 percent gain had helped boost the S&P last year—lost 4 percent last week. The iPhone and iPad maker is down nearly 17 percent in 2013.
Meanwhile, Dow stock General Electric lost 1 percent last week. But shares have seen a solid 10 percent gain in 2013—building on last year's 17-percent advance.
