Stocks continued their selloff mid-afternoon Monday with investors finding little reason to jump back into equities as the risks over oil and earnings persisted. 

The S&P 500 was down 2.6%, its worst one-day performance since mid-January, and the Dow Jones Industrial Average slid 2.4%, or 360 points. The tech-heavy Nasdaq fell 3.3% to levels not seen since mid-2014. 

Investors instead turned to safe-haven assets such as gold given there was no clear end in sight for the equity selloff. U.S. gold hit its highest level since June on Monday with spot gold climbing as high as $1,201 an ounce over the session. Gold has increased more than 12% since the beginning of the year. 

U.S. stocks have been on a downward slide since the beginning of the year on a laundry list of worries. Whether it was oil, the health of the U.S. economy, or a series of weaker earnings across a number of sectors, investors have had more than enough to push them into panic mode. The S&P 500 has fallen more than 10% since the beginning of the year. 

A number of disappointing earnings in tech, including Apple (AAPL) - Get Apple Inc. (AAPL) Report and LinkedIn (LNKD)  in the past couple of weeks, have pressured the sector. High-momentum tech stocks were among the worst performers on Monday. Industry giants Amazon (AMZN) - Get, Inc. Report , Microsoft (MSFT) - Get Microsoft Corporation (MSFT) Report and Alphabet (GOOGL) - Get Alphabet Inc. Class A Report traded lower, while the Technology Select Sector SPDR ETF (XLK) - Get Technology Select Sector SPDR Fund Report slid 2.1%.

"The bottom line is even after Friday's selloff, the market is vulnerable to another period of heightened volatility, following a negative reaction to Friday's employment data, standard expiration less than two weeks away, and the CBOE Market Volatility Index ... pushing higher near the 23.90 area -- double last year's low," Todd Salamone, senior vice president of research at Schaeffer's Investment Research, wrote in a note.

Uncertainty over the Federal Reserve's rate hike plans also contributed to downward momentum. Investors are concerned that the Fed will move forward with additional rate hikes following December's move even as the economy shows signs of weakness. Fed Chair Janet Yellen's semi-annual testimony to Congress on Wednesday and Thursday will be closely watched for hints on the central bank's future plans.

"The markets will have their ear to the ground to listen for any clues as to whether Yellen still sees March as the correct timing for the next rate hike," said Chuck Butler, managing director of EverBank Global Markets. "She'll have all of the markets' attention, as the data cupboard is light this week and we have to wait until Friday to see January's retail sales."

Crude oil struggled to hold above $30 a barrel on Monday as oversupply concerns and weaker global growth kept commodity traders at bay. The fresh selloff comes after a meeting between Saudi Arabia and Venezuela over the weekend to discuss possible coordination to cut production, though no future steps were announced to address the problem. West Texas Intermediate crude oil was down 1.5% to $30.43 a barrel on Monday morning. Prices have fallen 21% since the beginning of the year.
