$UNH stock down 15% today so far as CEO Andrew Witty steps down, company suspends annual forecast

$UNH, UnitedHealth Group Stock down over 15% today after CEO Andrew Witty steps down and they suspend their annual forecast.
This is a huge move for a stock like UNH—what’s going on behind the scenes?
Leadership shakeup + no forward guidance = not a good combo.

If one of the biggest healthcare players is dropping like this, could this drag down other names in the sector too? Might see XLV and other managed care stocks reacting.

Is this just a short-term reaction or something more serious? Curious what you guys think.
