1. Stock futures, bond yields drop after weak jobs data

U.S. stock futures fell Wednesday after weaker-than-expected jobs data. The S&P 500 on Tuesday broke a two-session losing streak and closed at a record high as broad market strength outweighed travel stocks held back by Covid fears. The Dow Jones Industrial Average also rose Tuesday for the first time in three sessions and finished fractionally shy of last week's record close. The Nasdaq advanced Tuesday and ended about 0.5% away from last week's record close.

The 10-year Treasury yield fell Wednesday to around 1.14% after of the before-the-bell release of ADP's July private-sector employment report. U.S. companies added just 330,000 jobs last month, far short of estimates of 653,000 positions. During the Covid-era, the ADP report has not be a great indicator of what the government might report in its July employment report, which is set for release Friday.

2. Robinhood jumps for second straight day, way above IPO price

Shares of Robinhood jumped about 16% in the premarket after surging more than 24% on Wednesday, blowing past last week's $38 initial public offering price. The wildly popular stock trading app fell 8% in its debut Thursday. It crept up Friday and Monday before rocketing higher Tuesday to $46.80 per share. Robinhood appears to be garnering attention from retail investors, after giving roughly a quarter of its IPO shares to its own clients. It's a "top traded stock" on Fidelity, which is generally a good proxy for individual investor interest.

3. GM, CVS Health report quarterly earnings before the bell

General Motors on Wednesday reported second-quarter earnings of $1.97 per share. CNBC's Phil LeBeau reported that it's unclear whether analyst estimates of $2.23 per share accounted for $1.3 billion of warranty costs. Revenue of $34.17 billion handily beat estimates. GM upped its full-year guidance. In June, GM projected better-than-expected results in the second quarter despite the industrywide impact of the shortage, which also is causing record vehicle pricing and profits. Shares of GM were little changed in Wednesday's premarket.

CVS Health on Wednesday reported second-quarter earnings and revenue that beat expectations. The pharmacy chain raised its forecast for the year as spiking Covid cases in the U.S. due to the delta variant reenergize the nation's vaccination campaign efforts. CVS earned $2.42 per share on an 11% revenue jump to $72.62 billion. Shares were steady in the premarket.

4. FDA reportedly speeds up full-approval process for Pfizer vaccine

The FDA has moved up its timetable to fully approve the Pfizer-BioNTech vaccine, according to The New York Times. The sources who spoke to the Times said the U.S. regulator's unofficial deadline is Labor Day or sooner. White House chief medical advisor Dr. Anthony Fauci told CNN on Tuesday evening, "I do hope it's going to be within the next couple of weeks." The two-shot Covid vaccine is currently cleared for use in the U.S. on an emergency basis.

The CDC issued a new federal eviction moratorium. The ban, announced Tuesday, will be targeted at areas of the country experiencing high levels of coronavirus infections. It will last for 60 days until Oct. 3. The protection could cover around 90% of renters. The CDC's original eviction ban, which had been in effect since September, expired at the end of last month.

5. Yellen says Biden's agenda key to keeping U.S. recovery going

Treasury Secretary Janet Yellen will warn on Wednesday that enacting President Joe Biden's economic agenda is critical to maintaining America's status as the world's superpower, according to a copy of her remarks obtained by CNBC. Yellen, who preceded Jerome Powell as Fed chief, will deliver the address in Atlanta as part of a White House messaging blitz designed to rally the public behind the trillion-dollar bipartisan infrastructure bill and Democrats' even bigger $3.5 trillion spending plan.
