About Marvin C. Gao

The origin

Marvin C. Gao has been tracking growth stocks and analyst earnings estimates for over ten years. His interest in EPS revisions started from a single observation: the biggest stock winners — the 10x and 100x names — almost always began their runs at a point where analysts were suddenly raising their earnings forecasts. The EPS upgrade wasn't noise. It reflected a genuine improvement in the company's fundamentals before the broader market had priced it in.

The problem was tooling. Most financial data sources — Finviz, Yahoo Finance, and others — show a snapshot of the current EPS figure or a sample of estimates. Knowing a company's forward EPS estimate is $3.00 tells you something. Knowing it was $2.60 three trading sessions ago tells you something far more actionable. What matters isn't the number — it's the change, and knowing about that change on the day it happens.

Unable to find a tool that tracked this signal daily across the full market, Marvin started logging consensus estimate changes manually: pulling figures for dozens of stocks, recording them in a spreadsheet, comparing session by session. That process grew unwieldy, and eventually became Platinum Stock Analyzer — an automated pipeline that scans 20,000+ US-listed equities each trading day and surfaces the names where analysts are meaningfully revising their earnings outlooks.

Does the signal hold up?

The Top Performers tracker within the tool serves as an ongoing empirical check on the approach. Stocks that appeared in the screener's top EPS upgrade lists three to seven sessions before making large moves are documented there — not to predict the future, but to demonstrate that the signal has strong recall across major market themes over time. Most of the high-profile growth names and hot tickers in any given market cycle show up in the screener's historical data well before they became widely discussed.

Marvin built Platinum Stock Analyzer as a narrowing tool: from thousands of stocks down to a short list worth deeper investigation. His view is that the next generation of 10x and 100x stocks in the AI era will show up in EPS revision data before they become obvious to the broader market.

Data and methodology

EPS estimate data is sourced from a financial data aggregator that collects sell-side analyst forecasts across US-listed equities. The screener computes day-over-day changes in the consensus estimate and applies a minimum EPS growth filter to exclude low-quality or near-zero earnings situations where percentage swings are misleadingly large.

The pipeline runs once per trading day, after market close. Results are typically available by early evening US Eastern time. Historical snapshots are stored indefinitely so you can review any prior session. Read the full methodology →

What this tool is not

Platinum Stock Analyzer is not a recommendation engine. A stock appearing at the top of the EPS revision list is a signal worth investigating — not a buy signal. Valuation, sector dynamics, chart setup, and individual company risk all matter. Use this screener to build a high-conviction watchlist, then do your own research before making any investment decision.
