What the score picked, and what happened next
Every week the top fifth of the S&P 500 by score and the bottom fifth are written down with that day's prices, and followed from then on beside every company in the index. It started on Oct 7, 2026 and only moves forward: nothing here is a backtest, and nothing can be tuned after the fact.
| Picked | Top fifth | Bottom fifth | All 500 | Top vs all |

The oldest group has been followed for 16 trading sessions. Over weeks, prices move for reasons no score can see; read nothing into this until it has run for months.
How it is counted
- Equal weight. Each group's day is the average of its members' price changes, as if the same amount were held in each and evened out every day. "All 500" is every company in the index, counted the same way.
- Price only. Dividends and trading costs are not included.
- Fixed at the pick. A group keeps the companies it was picked with, whatever their score does afterwards. One that leaves the index stops counting.
- Splits. A one-day fall of 40% or more, or a rise of two thirds or more, is set aside for that day. That removes a 2-for-1 or larger split and, rarely, a real crash. A smaller split, such as 3-for-2, is set aside when the price feed restates the day before's close for it, on a night that follows the last one counted; after a missed night it is counted as that day's move.
- The method as it stood. Each group was picked by the score as it was that week. When the method changes, earlier groups are left as they were picked.
A score that does no better than the index over a long run is still a way to read the filings quickly. That is all it claims to be. How the score works.
