Signals

Signals collects three things that are not fundamentals: stocks moving more than usual, stocks being talked about more than usual, and public statements by policymakers that name a company or a sector.

Unusual movers#

• A mover is a stock whose day change is large compared with its own recent behaviour and with the market.
• The largest movers of a session are researched. A mover shows a reason only when that research found one in dated sources. See When we give a reason for a move.
• Fresh movers appear before their explanation is ready, marked as pending.

Reddit#

• We scan a fixed list of investing subreddits and count mentions per stock.
• A spike is a count well above that stock's own normal level.
• The mood label is a model's reading of the posts. It is labelled as such and is the least reliable figure on the page.

Policy posts#

Posts by the US president that name a company, a sector or a trade measure, with the names affected and the time posted. We show the post and what it names. We do not forecast its effect.
