Short answer

Ahead of major scheduled events, markets are often filled with rumor, speculation, and leaked or partial information, and prices can move meaningfully on this chatter well before any official release occurs. This happens because market participants try to position ahead of anticipated news, and any credible-seeming leak, anonymous source, or informed guess can shift sentiment in the interim.

This happens because market participants try to position ahead of anticipated news, and any credible-seeming leak, anonymous source, or informed guess can shift sentiment in the interim. Some of this speculation turns out accurate; a great deal of it does not, and prices that moved on a rumor can reverse sharply once the actual outcome is confirmed or denied.

Unconfirmed reports, especially those citing anonymous or unnamed sources, warrant particular caution before being treated as reliable.
Price moves based on speculation can be just as sharp as moves based on confirmed data, but they carry the added risk of a rapid reversal if the rumor proves inaccurate.
Distinguishing between an official statement from a recognized source and secondhand commentary is an important habit when evaluating pre-event chatter.

Because acting on unverified speculation carries meaningfully different risk than acting on confirmed information, it's worth being deliberate about the difference between the two, and being comfortable that some position-relevant news will always remain uncertain until confirmed.
