Point-in-time backtesting platform for value investors
A SaaS platform that provides individual investors with survivorship-bias-free point-in-time fundamental data, automated DCF backtesting, and proper statistical testing. Users can define valuation rules before running backtests, test multiple holding periods, and validate strategies against historical data.
為什麼這很重要
You spend hours building a DCF model to value stocks, but when you try to backtest it, you realize you need 13 years of point-in-time SEC filings, exact treasury yields on each date, and delisted companies that went to zero. Your data only covers companies still listed today, making your backtest look better than reality. You manually code statistical adjustments for overlapping return windows and discover your trailing-growth input systematically selects value traps. Without affordable access to clean historical data and proper testing frameworks, you cannot trust your own model enough to invest real money based on it.
- · 專為 Individual value investors and quantitative researchers who build their own DCF models and want to validate them against historical data without paying for Bloomberg terminals. 打造。
- · 最可能的變現方式：SaaS subscription。

為什麼這件事可能失敗
自我反駁——最重要的信任度信號
- 1Data licensing costs for survivorship-bias-free historical data may exceed what individual investors are willing to pay, making the unit economics unsustainable.
- 2The target audience of serious individual value investors may be too small and too price-sensitive to sustain a SaaS business, especially if they can approximate results with free tools.
- 3Regulatory scrutiny could increase if the platform is perceived as providing investment recommendations rather than research tools, requiring costly compliance measures.
證據綜述
AI 如何合成此洞察——無原話引用
The original poster spent significant effort manually building a point-in-time backtest over 13 years, noting delisted names as a key weak spot. Multiple commenters identified survivorship bias and overlapping return windows as critical statistical issues. Several users expressed interest in the published research and shared their own DIY backtesting platforms, indicating unmet demand for an accessible solution. The discussion revealed that proper point-in-time data handling and statistical robustness are beyond what most individual investors can build themselves.
