2. -- Nvidia Rises on Second-Quarter Earnings Beat

Nvidia (NVDA) - Get Report  rose 5.63% to $157.15 in premarket trading Friday after the maker of graphics chips posted adjusted second-quarter earnings and revenuethat were higher than estimates.

4. -- General Electric CEO Buys $2 Million of GE Stock

General Electric (GE) - Get Report  CEO Lawrence Culp bought about $2 million of the company's stock after an accounting expert who flagged issues surrounding Bernie Madoff's investment fraud accused the industrial giant of inaccurate and fraudulent financial filings with regulators. 

According to a Securities and Exchange Commission filing from GE after Thursday's closing bell, Culp bought 252,000 shares at $7.93 each.

General Electric shares rose 2.12% to $8.18 in premarket trading Friday following a decline Thursday of more than 11%. The tumble followed an article from The Wall Street Journal that cited a research report from Harry Markopolos that found GE's insurance unit would need a boost of $18.5 billion to its reserves. He also told the Journal that other accounting issues, including in GE's oil and gas business, would amount to around $38 billion. Markopolos later told CNBC that he considered GE a "bankruptcy waiting to happen." 

"GE will always take any allegation of financial misconduct seriously. But this is market manipulation - pure and simple," Culp said in a statement on Thursday. "Mr. Markopolos's report contains false statements of fact and these claims could have been corrected if he had checked them with GE before publishing the report." 

5. -- Donald Trump Wants to Buy Greenland. Really?

Former real estate developer and now president, Donald Trump wants to buy Greenland - or so says a report in The Wall Street Journal.

The idea of the U.S. purchasing Greenland has captured Trump's imagination, the Journal reported, citing people familiar with the discussions. Trump has, with varying degrees of seriousness, repeatedly expressed interest in buying the Danish territory between the North Atlantic and Arctic oceans, the people said.

A Trump ally told the Associated Press that the president had discussed the purchase but wasn't serious about it. A Republican congressional aide said Trump brought up the notion of purchasing Greenland in conversations with lawmakers enough times to make them wonder, but they have not taken his comments seriously. 

It wouldn't be the first time an American leader tried to buy Greenland, the world's largest island, an autonomous territory of Denmark. In 1946, the U.S. proposed to pay Denmark $100 million to buy Greenland after flirting with the idea of swapping land in Alaska for strategic parts of the Arctic island, according to the Associated Press.
