Corporate Action Data Sources for Equity Research

Article Quant Q&A · Author: Michael WS
Read the original

Summary

The document asks where a small team can obtain corporate action data, including ticker changes, dividends, splits, acquisitions, and delistings. It names several commercial providers, such as Mergent, SIX Financial Information, Morningstar, and Interactive Data, and notes that cost and vendor processes may matter when selecting a service. Another response suggests Markit as a source.

The discussion also raises the operational work involved in building an internal feed: collecting notices, parsing them, processing updates accurately, and storing the resulting history. It does not compare vendor coverage, pricing, latency, or data quality, and it offers no detailed account of how major data providers source their records. The recommendations are individual responses rather than an independently evaluated shortlist, so availability and suitability would need to be checked for the intended market and budget.

Key ideas

  • Corporate action datasets may need to cover symbol changes, dividends, splits, acquisitions, and delistings.
  • The responses identify several commercial financial data vendors as potential sources.
  • Building an internal data process requires resources for collection, parsing, processing, and storage.
  • The document does not provide a comparative assessment of vendor coverage, cost, or accuracy.

Can someone recommend a good source for corporate action data? I need at the very least: ticker changes, dividends, splits, acquisitions and delistings. I historically used Bloomberg Back Office and am looking for a suitable replacement that is within a small team's budget besides just scraping a bloomberg terminal.

Edit: More generally where are the major places getting their data? Are they parsing each companies websites or some some sec filings that I am missing? Is it from DTCC?

Depends on your budget of course, but:

- Mergent offers a great service, expensive though.

- Six Financial Information offers good Corporate Actions service. (Personally, I would go with this one)

- Morning Star

- Interactive Data (very hard company to deal with, their legal would waste a lot of your time, but may still worth to get a quote)

Also, consider how much IT resources you have for accurately getting, parsing, processing and storing these data.
