What is When Issued (WI)?
When Issued (WI) refers to the conditional trading of securities that have been authorized but not yet formally issued or delivered. This mechanism allows you to trade these securities before they officially exist, with settlement occurring only after the issuance date.
This process facilitates early price discovery and market activity on securities such as bonds and stocks prior to their official release, linking closely to bond market dynamics and issuance.
Key Characteristics
Understanding the core features of when-issued trading helps clarify its role in financial markets.
- Conditional Settlement: Trades are agreed upon but settled only after official issuance.
- Price Discovery: Enables the market to establish prices before securities exist.
- Risk of Cancellation: If issuance is canceled, when-issued trades are voided.
- Common With Bonds and Stocks: Applies often to government securities and new stock issues, including bond ETFs.
How It Works
When-issued trading starts after a company or government announces a new security but before the actual delivery date. Market participants enter into trades with the understanding that settlement will occur only once the securities are formally issued.
This conditional framework allows you to buy or sell the security in advance, effectively locking in prices. If the issuance proceeds as planned, trades settle normally; if not, all transactions are canceled. This process is particularly relevant in markets dealing with government bonds, where timing and price transparency are critical.
Examples and Use Cases
When-issued trading finds practical applications across various scenarios.
- Airlines: Shares of companies like Delta may trade on a when-issued basis during stock splits or spinoffs before final issuance.
- Government Bonds: Prior to auctions, treasury securities often trade WI, reflecting anticipated auction results and pricing.
- Corporate Merger Shares: In mergers, new shares to be issued by the acquiring company can trade when-issued, enabling investors to position ahead of deal closure.
Important Considerations
When dealing with when-issued securities, be aware that the conditional nature introduces settlement risk if issuance is canceled. You should monitor announcements closely and understand that price volatility can be higher during the when-issued period.
Incorporating when-issued trading insights into your strategy can improve timing and price discovery, especially if you are active in markets featuring bond or equity issuance events.
Final Words
When-issued trading lets you engage with securities before they are officially issued, offering a chance to lock in prices early but carrying settlement risks if issuance doesn’t occur. Monitor issuance announcements closely and consider how timing fits your strategy before committing to WI transactions.
