How the EPS Revision Screener Works
Platinum Stock Analyzer runs a daily data pipeline that identifies stocks where Wall Street analysts have meaningfully changed their earnings estimates. Here is exactly how the screener works — from raw data to the daily watchlist you see on the dashboard.
Step 1 — Data collection
Every trading day the system pulls analyst consensus EPS estimates for thousands of stocks. The data covers forward EPS estimates — specifically the next fiscal year — which is the figure institutional investors weight most heavily when valuing growth stocks.
Estimates are timestamped so we can compare today's consensus against the prior trading day's consensus with precision. Small rounding differences are ignored; only genuine analyst revisions are counted.
Step 2 — Revision detection
For each stock, the screener computes the delta: the percentage change in the consensus EPS estimate from one session to the next. Stocks are then ranked by the magnitude of that delta — both upward revisions (analysts raising estimates) and downward revisions (analysts cutting estimates).
The top movers in each direction form the daily Top Increases and Top Decreases lists you see on the dashboard. New entrants to the screener universe and stocks that drop out of it are also flagged separately.
Step 3 — The EPS growth filter
The screener only surfaces stocks that already meet a minimum EPS growth threshold for the next fiscal year. This filters out companies where analysts are revising estimates around a loss or near-zero earnings base — situations where percentage changes can be misleadingly large.
Focusing on profitable, growing businesses means revisions are more likely to reflect genuine business momentum rather than noise.
Step 4 — Daily snapshot archive
Every day's output is stored as a dated snapshot. You can use the date picker on the dashboard to scroll back through prior sessions and study how the revision landscape evolved — useful for backtesting ideas or understanding how early a signal appeared before a stock made a large move.
Why EPS revisions work as signals
Academic research — including work by Narasimhan Jegadeesh and Sheridan Titman on price momentum, and subsequent studies on earnings momentum — shows that stocks with rising analyst estimates tend to outperform over the following 3–12 months. The mechanism is straightforward: when analysts raise estimates, institutional fund managers re-run their valuation models, often triggering buy orders.
The edge is timing. Retail investors rarely see a meaningful revision until it shows up in financial media — days or weeks after the fact. This screener surfaces the revision the same day it happens.
What the screener does not do
The screener is a signal generator, not a recommendation engine. It does not account for valuation (a stock can be expensive even with rising estimates), macro environment, sector rotation, or individual company risk factors. Use it as a starting point for deeper research, not as a mechanical trading system.
