New macroeconomic data also factored into the bearish momentum. Challenger, Gray & Christmas published a report on Thursday showing that U.S. companies had laid off more than 153,000 employees in October. According to the report, monthly layoffs came in at their highest level since 2023.

Key Data Points
Investors weren't thrilled with Archer's Q3 update
Archer posted a net loss of $129.9 million on zero revenue in the third quarter. While the lack of revenue in the quarter was not unexpected, the loss for the period came in larger than anticipated.
In conjunction with the quarterly report, Archer announced that it had raised $650 million in funding by selling newly issued stock. The company also announced that it will be acquiring the Hawthorne airport in a $126 million, all-cash deal. The airport is located within several miles of LAX and will be used as base of operations for serving the area.
While the company said that it was targeting annual production of 50 eVTOL crafts, the company's expansion forecasts, net loss, and capital moves generally disappointed investors.
