1. Investors ditch Toshiba: Toshiba's stock is in a tailspin.

Shares in the company dropped another 20% in Tokyo on Wednesday after it warned of billions of dollars in losses related to its takeover of a nuclear business last year.

"We're still figuring out the exact numbers," Toshiba (TOSYY) CEO Satoshi Tsunakawa said Tuesday. "I'm deeply sorry about all the concerns and possible damages this unprecedented situation may bring to all the stakeholders."

Toshiba had been working to recover from a $1.2 billion accounting scandal discovered last year. Even after suffering heavy losses this week, its shares are still up 25% in 2016.

2. Qualcomm in trouble: Qualcomm (QCOM) is facing an $865 million fine in South Korea.

Qualcomm said the Korea Fair Trade Commission issued the penalty after finding it had violated the country's competition law.

The technology firm called the ruling "unprecedented and insupportable" and said it "lacks a coherent theory of competition law violations."

Qualcomm plans to appeal the decision.
