Honeywell Drops 4.3% in a Single Session From Its $228 Open

Honeywell spent the entire session under pressure, sliding to $218.36 by late afternoon. That is a move that stands out for a mega-cap industrial that rarely swings this hard.

The selling never let up: an attempted stabilization around $224 gave way to fresh lows into the close.

The same session saw Air Products and Chemicals, a Honeywell partner, file its quarterly earnings report. The card facts note the timing of that filing alongside the move, though no specific figures from that report have been attributed as a cause of Honeywell's slide.

For investors watching the stock, the level to track is the $228 open. Failing to reclaim it in coming sessions would signal that the opening level has shifted from support to resistance.
