Quantitative research · Silverton, Oregon

Hedge-fund-grade research, built for individuals.

Stock Sweeper is building the kind of systematic, data-driven trading program that is usually reserved for firms managing billions, and designing it so individual traders can use it, and eventually pool their signal together.

The problem

Institutional tools are locked behind institutional capital.

Traditional managers charge a percentage of your capital every year, whether or not they perform. The systematic, research-heavy programs hedge funds rely on are typically built for, and priced for, firms with billions under management.

Our mission: put a hedge-fund-style program in the hands of individuals, and combine many small traders to identify and amplify trade opportunities.

How it works

From thousands of data points to a short, ranked list.

Every trading day the platform sweeps a focused cohort of stocks, scores each one on multiple independent lenses, and surfaces the setups worth a closer look.

Daily screener

A curated cohort of roughly 250 stocks is refreshed every day with price, volume, and fundamental data.

Supply Pressure Score

Weighs share dilution against compression using SEC filings, short interest, borrow, and options data.

ML trade scores

Walk-forward machine-learning models rank opportunities using only information available at the time.

Timing research

Intraday entry and exit studies inform when, not just what, to trade.

Supply Pressure, at a glance

Is the float about to expand through offerings and dilution, or is supply being squeezed? The score condenses filings and market-structure data into one readable gauge.

SEC filings research

Automated parsing of company filings flags events like shelf registrations, offerings, and insider activity that change the supply and risk picture of a stock, often before it shows up in price.

Technology & research rigor

Built to be honest with itself.

The easiest way to fool yourself in quantitative finance is with a backtest. Stock Sweeper's research process is designed around avoiding that.

↻

Walk-forward testing

Models are trained on the past and evaluated on the period that follows, then rolled forward. They never see the future.

⊘

No lookahead

Features are timestamped to when the data was actually public, so filings, short-interest reports, and prices can't leak into earlier decisions.

✓

Out-of-sample validation

Results are judged on data the model never trained on, and signals must hold up across different market regimes.

Track record

Verified track record coming.

We will publish performance only once it has been independently verified. TODO: verified track record & legal review before any performance is shown

During the AI boom he became interested in investing and set out to build his own hedge fund software. Along the way the goal grew: why should this kind of program only exist for firms with billions?

"The goal is to combine the little traders together, to identify and amplify trade opportunities."
