- The report introduces a quantitative model named "250-Day New High Distance" to track market trends and identify leading stocks. The model calculates the distance between the latest closing price and the highest closing price over the past 250 trading days using the formula: $ 250\text{-Day New High Distance} = 1 - \frac{\text{Close}_{t}}{\text{ts\_max(Close, 250)}} $ where $\text{Close}_{t}$ represents the latest closing price, and $\text{ts\_max(Close, 250)}$ is the maximum closing price in the past 250 trading days.
