US stock market just shed $550 billion in 25 minutes after ISM PMI hit a 3-month low.

This is what happens when macro data misses expectations in a fragile market structure. The ISM manufacturing index came in weaker than forecast, and algos immediately repriced risk across equities.

A few things worth noting:

1. Speed of the selloff shows how thin liquidity is right now. When everyone's positioned the same way, exits get crowded fast.

2. PMI weakness signals slowing economic activity, which normally would be bullish for rate cuts. But the market's reading it as "growth scare" instead of "Fed pivot."

3. This kind of violent intraday move usually precedes either a sharp bounce (if it's just a liquidity flush) or the start of a deeper correction (if the macro story is actually breaking).

We're in that zone where bad news is just bad news again. Not the environment where you want to be overexposed or overleveraged. Watch how price behaves into the close and whether we get any stabilization or continued follow-through selling.
