Modeled downside range
The 90% range frames modeled downside and upside around the expected outcome. It is not a maximum-loss guarantee.

Five full sample scans
Each ticker is added to a demo portfolio of the other four. Open one to see the complete paid output: single-stock risk against the SPY benchmark, position sizing checks, sector exposure and correlation. A paid plan runs the same scan on your own watchlist.

Stock Risk Analysis
Review downside, sizing and concentration before a trade
The pre-trade risk scan is a Pro decision-support workflow. It evaluates only the risk fields returned by HPSILab, including modeled ranges, the stock's own risk against the SPY benchmark, sizing checks, and concentration and correlation against a watchlist when available.
Stock vs SPY benchmark
Volatility, beta, 1-day VaR and 1-year max drawdown of the stock on its own, next to the same metrics for SPY over the same window. This compares two securities; it is not the risk of a portfolio before or after the trade.
Sizing and concentration checks
Pass, warning and failure statuses summarize explicit API thresholds. Correlation and concentration are measured against a watchlist treated as equal-weight, not against your actual holdings.

Frequently asked questions
Is a pre-trade scan a buy or sell signal?
No. It is a risk review designed to support position and exposure decisions.
Does the 90% range cap losses?
No. Markets can move outside modeled ranges, especially during gaps, liquidity stress or regime changes.
Why is this tool Pro?
Live scans run the same risk engine on any supported ticker and add concentration and correlation against your own watchlist, on eligible HPSILab plans.
