Ticker Changes

A ticker change, or more precisely a name change, is a rebranding event. The company changes its name, ticker symbol, and/or CUSIP, in any combination. No balances move and no cash is paid; only the identity changes.

Two things to know:

• A name change sometimes arrives alongside a reverse stock split, so both events can hit the same security in the same week.
• A CUSIP change matters even when the ticker looks identical, because the CUSIP is what follows the security through settlement.

What changes at Dinari

When the symbol or CUSIP changes, Dinari swaps in new internal records for the security and updates the dShare™ token name.

The asset goes quiet for a while

When the identifier changes, the old asset dShare is disabled and a new one is issued. Until Dinari re-points its records at the new identifier, the asset is disabled on the platform and all orders for it will be rejected.

How it works, from your side

    autonumber
    participant D as Dinari
    participant P as Partner
    participant U as End user
 
    Note over D: Name / symbol / CUSIP change — asset disabled
    D->>D: Verify the new asset,<br/>check for affected orders
 
    Note over D,P: Asset unavailable — orders rejected
    P->>D: Order submission
    D-->>P: Rejected — asset disabled
    P->>U: Show "temporarily unavailable"
 
    D->>D: Re-point records to the new asset,<br/>update token name, re-enable
 
    Note over D: Asset re-enabled — trading resumes
    D->>P: Confirmation of new symbol
    P->>D: Read portfolio
    D-->>P: Same amount, updated symbol<br/>and token metadata
    P->>U: Refresh mapping, display new symbol

Before re-enabling, Dinari validates that the asset is active again, all records reference the current asset, no orders or positions were affected, and share quantities are unchanged.

Recommendations

1. Key off stock_id, never the ticker symbol. Treat symbol as a display field you refresh from the API. This is critical to ensuring that you are not impacted by ticker changes.
2. Automatically handle rejections gracefully during the window. Show "temporarily unavailable" rather than a raw error, and back off on retries.
3. Refresh metadata afterwards. Re-read the portfolio and update your cached stock_id → symbol and token_address mapping.
4. Don't adjust balances. Quantities don't move in a name change. If one did, check for a reverse split in the same window and contact your Dinari representative.
