Ad-hoc disclosure
In briefThrough an ad-hoc disclosure, an issuer makes price-relevant inside information publicly available without delay, unless it lawfully delays publication. For small caps it is often the first formal channel through which market-moving news becomes visible.
Definition
An ad-hoc disclosure is the public announcement of inside information by an issuer, provided there is no permissible delay of publication.
How it is calculated
Formula. No metric. The decisive factors are in particular Art. 7 and Art. 17 MAR as well as the issuer's specific circumstances.
Why it matters for small caps
For small caps often the most important monitoring trigger, since material news here surfaces first and in formal form.
Common misreadings
- Not every important corporate news item is legally inside information. Conversely, a brief announcement can have significant financial consequences.
In the process
Frequently asked
What is an ad-hoc disclosure?
It is the legally required, immediate publication of information that could materially affect the share price. The legal framework is primarily Art. 7 and Art. 17 of the Market Abuse Regulation.
How do investors use ad-hoc disclosures?
Investors use them as an early-warning system to capture material developments promptly. For small caps it is worth continuously monitoring an issuer's flow of announcements.
What misjudgements are common with ad-hoc disclosures?
Not every important news item legally meets the definition of inside information, and conversely a tersely worded announcement can carry heavy financial weight. Form and length say little about the actual significance.
