S&P 500

This Finforge-N3 AI model flow starts with the S&P 500 as the asset universe, then chains together three AI model nodes: Screener-N3, Forecast-N3, and a second Screener-N3 before portfolio construction.
The idea is simple: first narrow the universe to more interesting candidates, then forecast their near-term return potential, then select the Top N forecasts to optimize against a benchmark before sending the results into portfolio construction. This creates a practical workflow where screening, forecasting, selection, and position sizing work together instead of as separate steps.
In this template, Screener-N3 uses data types including Net Margin and Revenue. Net Margin is the share of revenue that remains as profit after all expenses, interest, and taxes; it summarizes how efficiently the company turns sales into bottom-line earnings. Revenue is the top-line sales figure, which helps describe the company’s scale and demand; growth and consistency in revenue can signal whether the business is expanding or stalling.
Together, these inputs give the screener both a profitability lens (how much the company keeps from sales) and a scale/growth lens (how much the company sells and whether it’s growing).
Screener-N3 is an AI model node that continually learns from new market dynamics instead of relying on fixed screening rules. Its role is to filter the S&P 500 toward stocks with stronger potential versus the benchmark.
The selected names are then passed to Forecast-N3, another AI model node, built for continual deep learning forecasting. Forecast-N3 focuses more directly on price dynamics and estimates near-term return direction and magnitude.
After forecasting, the second Screener-N3 ranks and selects the Top N forecasts to create a tighter candidate set for benchmark-aware optimization in portfolio construction.
Chaining the nodes is meaningful because they solve different parts of the problem. Screener-N3 helps reduce noise by finding better candidates, Forecast-N3 complements it by analyzing price behavior and short-term timing, and the second Screener-N3 concentrates the signal by selecting the strongest forecasts before optimization and position sizing.
