Stocks ended a volatile week with modest gains Friday, but the S&P 500 had its worst week in three months.
The Dow Jones industrial average, the S&P 500 and the Nasdaq all ended higher, shaking off earlier weakness. The Nasdaq was the best performer, adding nearly 0.4%. The Dow and S&P 500 both gained about 0.1%.
Is a correction brewing? Despite Friday'sgains, the S&P 500 ended the week down 0.9%, the biggest weekly decline since April. The Nasdaq was down 1.6% and the Dow was off 0.7%.
Dave Rovelli, managing director of U.S. equity trading at Canaccord Genuity, said many investors are wondering if the market is on the verge of a long-awaited correction, typically defined as a drop of 10% or more from the most recent high.
The Russell 2000 index of small company stocks, often seen as a leading indicator for the broader market, fell nearly 4% this week. Stocks haven't experienced a correction in quite some time, and many investors would welcome the opportunity to buy into the market at more attractive prices.
"The market is still in a long-term up trend," said Rovelli. "A pullback wouldn't be the worst thing in the world, and it would give people a better entry point."
While there's a lot of choppiness in the markets this week, experts told CNNMoney that stocks will continue to go up this year. On average, they expect the S&P 500 to finish the year about 9% higher (it's currently up just over 6%).
