Why this matters for beginners
Understanding this helps you stay calm and read price moves correctly. This is general education, not personal advice.
Main explanation
A rumour of a takeover can lift a share before any offer exists.
If the rumour is false, the price often falls back.
If it is confirmed, the move may already be done, so the price barely reacts.
Social media spreads rumours fast, and some are deliberately false.
Example using a real company
Fictional Sunny Bikes rises 10 percent on a takeover rumour, then falls 8 percent when the buyer denies it.
- →Rumour: up 10. Denial: down 8.
- →Rumour: up 10. Confirmed: up 1 more.
