T-Mobile, Comcast, and Joby Aviation Stocks Slump to 52-Week Lows
Shares of T-Mobile US, Inc. (TMUS), Comcast Corporation Class A (CMCSA), and Joby Aviation, Inc. (JOBY) dropped to 52-week lows on Friday.

The steep decline reflects investor concerns over potential industry disruption and company-specific headwinds.
