Sixteen Republican senators approve of another $25 billion in airline aid

Sixteen Republican senators on Wednesday announced their support for $25 billion in additional federal aid to support the airline industry as it struggles with a pullback in business related to the Covid-19 pandemic.

Earlier this year, U.S. passenger airlines were allocated $25 billion in aid that would preserve sector jobs until Oct. 1. Despite that funding, carriers have started telling tens of thousands of workers that their jobs are at risk when the relief terms expire this fall.

"For these reasons, we support a clean extension of payroll support for passenger air carrier employees included in the CARES Act to avoid furloughs and further support those workers," the GOP lawmakers wrote in a letter, which was seen by CNBC, to Senate Majority Leader Mitch McConnell and Senate Minority Leader Chuck Schumer.

Airline stocks jumped in unison following the news. Shares of American Airlines surged 9%, while United and Delta jumped bout 3% each. — Thomas Franck, Leslie Josephs

Teladoc deal is a 'healthy premium' for Livongo shareholders, analyst says

SVB Leerink health technology analyst Stephanie Davis said she was surprised that shares of both Teladoc and Livongo Health fell on Wednesday after the companies announced that Teladoc would acquire Livongo in a cash and stock deal valued at about $18.5 billion. Davis said that, given the size of the merger, pressure on Teladoc was expected but she was looking for Livongo's stock to hold up better.

"I know there's some frustration that I've seen among some holders that they thought Livongo had further to move, but I don't know. This is a very healthy premium for a stock that's already had a, before today, 477% run," she said. 

Davis said she thought the deal made sense but would take time for Teladoc to see the benefits. Shares of Teladoc have dropped more than 16%, while Livongo's stock has slid 9%. — Jesse Pound

White House appears to make concessions on jobless benefits offer

After days of gridlock, top Democratic and Republican negotiators appeared to be approaching a compromise with each side making concessions over the next stimulus bill. The most recent sign of thaw came from the White House, which appeared to yield slightly on its opposition to continued federal support for unemployment benefits.

The Trump team offered to extend extra federal unemployment insurance into December at $400 per week, NBC News and Politico reported. Treasury Secretary Steven Mnuchin and White House chief of staff Mark Meadows also offered to extend a moratorium on evictions from federally backed housing into December.

Democrats, meanwhile, cut their request for U.S. Postal Service funding to $10 billion from $25 billion, according to the reports. — Thomas Franck, Jacob Pramuk

Bond ETF assets cross $1 trillion mark for the first time

A stampede into bonds in 2020 has pushed total assets for fixed income exchange-traded funds over the $1 trillion landmark for the first time. Four straight months of more than $20 billion in inflows to bond ETFs has taken the year-to-date total to $125.8 billion and just over that $1 trillion level in total assets under management, according to State Street Global Advisors. That growth represents 14.8% in total AUM. The trend comes as government bond yields hover around historic lows and spreads compress in corporate fixed income. "The picture of these flows is likely in the dictionary next to the term 'being active with passive instrument,' as investors have leveraged fixed income ETFs to recalibrate portfolios based on prevailing macro trends," said Matthew Bartolini, head of SPDR Americas research at State Street. — Jeff Cox

BigCommerce spikes more than 200% after IPO

Investor sentiment "cautious" ahead of Uber and Lyft earnings, analyst says

JPMorgan said on Wednesday morning it sees a "slower recovery" for the ridesharing companies as they continue to be impacted by the coronavirus ahead of their earnings. Lyft reports on Aug. 20 while Uber reports on Aug. 6.

The firm kept its overweight ratings on Uber and Lyft but slightly lowered its price targets on the stocks. "We continue to expect the rideshare rebound to be highly localized, but we remain positive on broader structural recovery over time," Anmuth added.
