The casebook
Ten real headlines. What Ripple said. What the market did.
We froze Ripple's map on 2026-01-21, then fed it ten big headlines from the months after. For each one it named five stocks and a direction. Below is every call, checked against the S&P 500 twenty trading days later. Nothing here was picked after the fact.
How to read this honestly
- “Right” means the stock beat the S&P 500 in the direction Ripple called. A call that a stock falls is right if it lagged the index.
- Ten headlines is a small sample. Treat this as a sanity check that the map points the right way, not as proof of an edge.
- After five days it's a coin flip. The map is about knock-on effects, and those take weeks to show up in prices.
- Ripple describes exposure. It is not investment advice, and none of this was traded.
