Why does a stock's score change from one day to the next?
Because it is recalculated after every session on the latest prices. A score that moves does not mean the stock has changed in nature; it means its setup has changed since the day before.
A stock scored 76 on Monday and 71 on Tuesday has not necessarily changed in nature overnight. What changed is its setup: the score is recalculated after every session, on the latest closing prices.
What the site measures
Several things can move a score from one day to the next:
- Prices. Each closed session adds a candle. RSI, MACD, moving averages and volumes are recalculated, and an indicator that crosses a threshold gains or loses its points in one go.
- The learning model. It is retrained regularly on past data and adjusts the score by a few points, up or down.
- Fundamental data. It changes when a company publishes its accounts, so rarely, but all at once.
- The tone of the news. For stocks already in the top bands only, recent news and social media can add or remove a few points. That adjustment never moves a neutral stock into a top band.
The “What moved” page gathers those changes: the stocks whose signal changed band, and those whose score moved by at least three points since the day before.
What the measurement does not say
- That a small gap matters. A stock at 58 and a stock at 57 do not carry the same word, but they are in almost the same place. A band change near a threshold changes the label, not the stock.
- Why the price moved. The score describes the move; it does not give its cause. A lower score after a bad session says nothing about the reason for that session.
- That the trend will continue. A score that rises three days in a row describes three days. It does not promise the fourth.
How to use it
Look at how a score holds over time rather than at one day's change: a score settled for several weeks does not say the same as one that arrived yesterday. The calculation times are set out in the article on data updates.
