What is an RNS, and why does the price move?
IN SHORTAn RNS is an official company announcement in the UK. Companies must publish price-sensitive news promptly, so prices often move within minutes.
RNS stands for Regulatory News Service, the London Stock Exchange's service for company announcements. People use RNS to mean any official UK company announcement. US companies file similar news with the SEC.
UK rules require listed companies to announce inside information, news likely to move the price, as soon as possible. Most announcements arrive at 7:00am, before the market opens at 8:00am.
What moves the price
- Results and trading updates: better or worse than expected?
- Contracts, approvals and acquisitions.
- Fundraises (placings) that issue new shares.
- Profit warnings, which can cause big falls.
KEY POINTPrices move on surprise. Good news that everyone expected may not move the price at all.
