The National Highway Traffic Safety Administration (NHTSA) dealt a potential setback to Tesla’s (TSLA) autonomous ambitions with a new investigation into the company’s full self-driving (FSD) technology.

NHTSA said it had opened an investigation into Tesla’s FSD software over reports of four crashes where FSD software was engaged in an “area of reduced roadway visibility conditions.” NHTSA said reduced roadway visibility was due to conditions like sun glare, fog, or airborne dust, reports Yahoo Finance's Pras Subramanian.

Shares of the electric vehicle company were flat Friday afternoon.

NHTSA said in one incident a pedestrian was struck and killed and in another an injury occurred when FSD was engaged in reduced visibility conditions. NHTSA’s preliminary investigation would look into whether FSD’s controls could detect and respond to reduced roadway visibility conditions and if any other similar crashes occurred with FSD engaged, among other inquiries.

NHTSA said the investigation would cover 2.4 million Tesla EVs, which would be every vehicle with the ability to engage FSD in the US.

Here are some of the stocks leading Yahoo Finance’s trending tickers page during afternoon trading on Friday:

American Express (AXP): Shares of the financial services company close to 3% Friday afternoon even after reporting better than expected third quarter profit and lifting its full year guidance on strong consumer spending. But investors still pulled back after revenue came in slightly lower than analyst forecasts and as investors pushed the stock to a record high during the prior session on Thursday.

Coinbase (COIN): The digital asset platform rose more than 5% Friday afternoon, continuing to ride the momentum of Bitcoin (BTC-USD)'s recent surge. The most popular and valuable cryptocurrency has risen close to 10% for the week, approaching the $70,000 level. Coinbase is set to report third quarter earnings at the end of the month.

Netflix (NFLX): Shares of the streaming platform rose more than 9% Friday following a strong third-quarter earnings report, exceeding analysts’ expectations on both revenue and profits, driven largely by an expansion in its advertising business.

CVS (CVS): The pharmacy chain fell more 6% Friday morning following news that the pharmacy chain will replace its CEO Karen Lynch with another company executive, David Joyner. CVS also said in a release Friday that it expects adjusted third-quarter earnings per share of $1.05 to $1.10, lower than the $1.70 forecast by Wall Street analysts, according to Bloomberg consensus estimates.

Stock pointed upwards on Friday, as Netflix's muscular quarterly report provided optimism ahead of the next major wave of mega-cap earnings.

The tech-heavy Nasdaq Composite (^IXIC) moved up roughly 0.5%, while the S&P 500 (^GSPC) added about 0.3%. The Dow Jones Industrial Average (^DJI) rose just above the flatline after hitting a fresh record closing high.

All three gauges are set to post wins for the week, with the Nasdaq and the S&P up about 0.7%, and the Dow leading the way with an anticipated 0.9% gain.

In commodities, gold (GC=F) prices hit a new record, topping $2,700 an ounce for the first time. Concerns about a widening Middle East conflict and uncertainty about the outcome of the US presidential election prompted a shift to less-risky assets.

Apple stock jumped as much as 1.7% following an industry report showing a surge in China iPhone sales.

Wedbush analyst Dan Ives said in a note to investors Friday, citing data from Counterpoint Technology Market Research, that China iPhone sales rose 20% since Sept. 20 — when Apple launched its iPhone 16 and its Chinese rival Huawei released a new smartphone model. Apple's strong sales were led by its iPhone 15 models in particular, with sales of those phones jumping 44% year over year.

"This industry analysis is consistent with our recent Asia trip and supply chain checks that we believe China sales for iPhone 16 will show a strong rebound over the next year with the beginning of this AI driven super cycle led by iPhone 16," said Ives. "We believe 20% of the world's population will ultimately access AI through an Apple device over the coming years."

Apple iPhone sales in China have fallen behind Chinese rival Huawei this year. And analysts have voiced concerns that its initial iPhone 16 sales were weak, though recent data has eased those fears.

Netflix (NFLX) stock climbed more than 10% Friday after the streaming giant beat third quarter EPS and revenue estimates and projected sales for the current quarter that came in ahead of Wall Street's expectations.

The growth came as the streamer continued to lean on revenue initiatives like its crackdown on password sharing and ad-supported tier, in addition to last year's price hikes on certain subscription plans, reports Yahoo Finance's Allie Canal.

Subscribers also came in strong with another 5 million-plus subscribers added on the heels of breakout programming like "The Perfect Couple" and "Nobody Wants This."

Subscriber additions of 5.07 million beat expectations of 4.5 million and follows the 8.05 million net additions the streamer added in the second quarter. The company had added 8.8 million paying users in Q3 2023.

Investors have praised the company's foray into sports and live events. Meanwhile, its ad tier continues to gain traction, accounting for over 50% of sign-ups in the countries where it's offered during the third quarter.

Netflix (NFLX): Shares of the streaming platform rose more than 10% Friday following a strong third quarter earnings report, exceeding analysts’ expectations on both revenue and profits, driven largely by an expansion in its advertising business.

CVS (CVS): The pharmacy chain fell more 8% Friday morning following news that it will replace its CEO Karen Lynch with another company executive, David Joyner. CVS also said in a release Friday that it expects adjusted third quarter earnings per share of $1.05 to $1.10, lower than the $1.70 forecast by Wall Street analysts, according to Bloomberg consensus estimates.

Apple (AAPL): The tech giant rose 1% on news of healthy sales in China, which grew by 20% in the first three weeks of the iPhone 16 going on the market, according to Counterpoint Research data.

Moderna (MRNA): Shares of the pharmaceutical company fell more than 1% following reports that rival GlaxoSmithKline (GLAXO.NS) is suing for US patent infringement over COVID vaccines.

CVS (CVS) stock fell more than 6% following news that the pharmacy chain will replace its CEO Karen Lynch with another company executive, David Joyner.

Shares are down nearly 20% this year as the company has been under pressure from Glenview Capital Management, a hedge fund pushing for changes, according to the Wall Street Journal, which first reported the news of Joyner's appointment. CVS has been reportedly reviewing strategic options that could include a breakup.

David Joyner, the EVP of CVS Health and president of the chain's pharmacy health services business, CVS Caremark, replaced Lynch as of Thursday, CVS said. Lynch had been CEO since 2021. In an interview with the Journal, Joyner said the company would move forward intact.

CVS said in a release Friday that it expects adjusted third quarter earnings per share of $1.05 to $1.10, lower than the $1.70 forecast by Wall Street analysts, according to Bloomberg consensus estimates. CVS said investors should no longer rely on its previous full-year 2024 earnings guidance — which it has already repeatedly lowered — given "continued elevated medical cost pressures in the Health Care Benefits segment."

The final trading session of the week started with mostly positive results as investors welcomed Netflix's (NFLX) across-the-board earnings beat, which could serve as a preview for the megacap tech giants reporting next week.

The tech-heavy Nasdaq Composite (^IXIC) moved up roughly 0.5%, while the S&P 500 (^GSPC) added 0.3%. The Dow Jones Industrial Average (^DJI) fell about 0.1% after hitting a fresh record closing high.

The major stock gauges are all on track for a sixth consecutive weekly win after a strong showing by big banks to kick off earnings season.

Earnings: Ally Financial (ALLY), American Express (AXP), Comerica (CMA), Procter & Gamble (PG)

Economic data: Housing starts and Building permits (September)
