Listen to the news

Large-cap stocks tied to housing, nuclear energy, crypto mining and global commodities led Wall Street's biggest declines last week as investors reacted to earnings volatility, macro uncertainty and sector-specific pressure.

Rising Treasury yields, Middle East conflict concerns, weaker crypto sentiment and cautious outlooks weighed on several momentum-driven names despite some companies posting strong quarterly results.

These ten large-cap stocks were the worst performers last week. Are they a part of your portfolio?

Ubiquiti Inc. (NYSE:UI) slumped 14.62% this week after the company reported worse-than-expected third-quarter financial results.

JBS N.V. (NYSE:JBS) fell 17.05% this week after the company reported mixed first-quarter financial results. Also, Barclays lowered its price forecast on the stock from $23 to $21.

Korea Electric Power Corporation (NYSE:KEP) decreased 11.92% this week.

Rocket Companies, Inc. (NYSE:RKT) decreased 13.31% this week after the company reported better-than-expected first-quarter financial results.

Oklo Inc. (NYSE:OKLO) fell 12.83% this week after reporting first-quarter results. Shares of uranium and nuclear-related companies traded lower amid rising Treasury yields and a stronger dollar, which can weigh on the commodity. Inflation concerns related to the Middle East conflict may result in continued elevated interest rates and more costly project financing

AngloGold Ashanti (NYSE:AU) slumped 16.41% this week.

Carvana Co. (NYSE:CVNA) decreased 13.65% this week. BTIG analyst Marvin Fong maintains a Buy rating, lowering the price forecast from $485 to $97.

IREN Limited (NASDAQ:IREN) fell 3.3% this week. Shares of crypto-related companies traded lower as the price of Bitcoin drops below $80,000.

Talen Energy Corporation (NASDAQ:TLN) fell 14.13% this week. The firm said subsidiary TES refinanced and repriced two senior secured term loan facilities, extending maturities and lowering interest costs, with the transactions and recent note redemption expected to generate about $47 million in annual interest savings.

Posco Holdings Inc. (NYSE:PKX) slid 9.54% this week. Shares of U.S.-listed Korean companies traded lower amid rebounding energy prices and the threat of a prolonged U.S.-Iran conflict. Also, a proposal from a presidential adviser on distributing tax revenue from AI productivity to the public has caused volatility.
