Here are five things you must know for Thursday, Oct. 11:

1. -- U.S. Selloff Continues, Global Shares Sink

U.S. stock futures were down sharply on Thursday, Oct. 11, and global stocks fell dramatically after the Dow Jones Industrial Average plummeted 831 points on Wednesday, Oct. 10, the S&P 500 dived 3.3% and the Nasdaq sank 4.1% in its worst day of the year after tech stocks went into a tailspin.

Both the Dow and S&P 500 on Wednesday logged their largest losses on a percentage basis since Feb. 8. For the month, the Nasdaq has fallen 7.8%.

Contracts tied to the Dow Jones Industrial Average fell 224 points on Thursday, futures for the S&P 500 fell 22 points, and Nasdaq futures were down 54.75 points.

Investors rotated out of tech and growth stocks and into utilities on Wednesday as government bond yields continued their march higher. Tech stocks, such as Netflix Inc. (NFLX) - Get Report , down 8.4%, Amazon.com Inc. (AMZN) - Get Report , down 6.2%, and Alphabet Inc. (GOOGL) - Get Report , down 4.6%, were some of the leading decliners on Wednesday.

"I don't like what's happening," said Jim Cramer, founder of TheStreet, on Wednesday. "I could tell you that the velocity of the decline of the Nasdaq is extraordinary. The speed of the decline in the Nasdaq is usually not sustainable."

The yield for the 10-year Treasury note rose on Wednesday to as high as 3.23%. Early Thursday, the 10-year was yielding 3.172%. At the end of 2017, the 10-year note was yielding 2.4%.

Bond yields have been rising as recent strong U.S. economic data have investors anticipating the Federal Reserve will raise interest rates at a pace faster than expected.

Donald Trump suggested the Fed was to blame for the stock market selloff. The central bank has raised interest rates three times so far in 2018.

"I think the Fed is making a mistake. They're so tight. I think the Fed has gone crazy," Trump said Wednesday.

"Actually, it's a correction that we've been waiting for, for a long time," Trump said. "But I really disagree with what the Fed is doing, OK?"

Under the agreement, Apple will license certain of Dialog's power management technologies. Dialog also will transfer some of its assets and more than 300 employees to Apple.

Cupertino, Calif.-based Apple will pay $300 million in cash for the transaction and prepay $300 million for Dialog products to be delivered over the next three years.
