One word in a statement can move price more than a whole speech

[Shadow Trader]

Central bank statements are revised carefully, and traders compare each new version to the last. A single word change, such as replacing patient with flexible, can shift expectations about policy.

Algorithms trained on language scan the text instantly and trade the difference. The first move often follows the direction of the changed wording, even when the overall tone remains steady.

Humans catch up within a minute or two, and the initial reaction can reverse if the full context points elsewhere.

This is why a redline comparison of the new statement against the previous one is a common tool among professionals. Retail traders can do something similar by opening both statements side by side before the release and noting which phrases might change.

It is not a way to beat the algorithms, but it helps explain moves that seem out of proportion to the headline.

Worth asking around: have you ever noticed a small change in wording that explained a big move?
