Point-in-Time Equity Universe API
Build a developer-first API that returns historical index membership, delisted securities, and point-in-time tradable universes for equities. The product solves the most common early-stage quant mistake: using today's constituents and incomplete free data to test historical stock-picking strategies.
لماذا هذا مهم
You start with an ordinary stock-selection idea, pull prices from a free source, and only later discover your test universe quietly excluded many names that disappeared, merged, or left the index. The result looks cleaner than reality because your historical screen is built from survivors and incomplete constituent lists. Paid institutional datasets exist, but they feel expensive and operationally heavy when you are still validating ideas. What you really need is a simple way to ask, for any date, which names were actually eligible, which later delisted, and how exits should be represented so your research is not invalid from the first line of code.

لماذا قد يفشل هذا
الرد الذاتي — أهم إشارة ثقة
- 1Users may prefer established data vendors once they realize data quality matters, making it hard to win on trust alone.
- 2Historical universe accuracy may require data sources that are too costly to support attractive pricing.
- 3Some hobbyists only need a one-time download and will not sustain recurring subscription revenue.
ملخص الأدلة
كيف قام الذكاء الاصطناعي بتجميع هذه الرؤية — بدون اقتباسات حرفية
The discussion repeatedly returns to one issue: valid stock-selection backtests require date-correct index membership and delisted names, while common free workflows do not provide either. Roughly a dozen comments reinforced that historical constituent data is essential and that many users eventually pay for it. Several also pointed out that the problem affects even short backtests, making this a recurring need rather than a niche archival feature.
