- The report does not contain any quantitative models or factors for analysis[1][2][3]

- The report uses the Mahalanobis distance of weekly price and trading volume changes to measure industry crowding levels[3][17] - The construction process involves identifying industries in the first quadrant (price and volume both rising) and the third quadrant (price and volume both falling) and marking points outside the ellipse as industries with significant short-term deviations at a 99% confidence level[17] - The building materials industry experienced short-term trading overselling last week[3][18]

- The report uses Mahalanobis distance to measure industry crowding based on weekly price and transaction volume changes[3][17][18] - The construction process involves identifying industries where price and transaction volume deviate significantly, with industries outside the ellipse in quadrant 1 indicating short-term significant crowding[17] - Last week, the building materials industry showed significant trading crowding[18]

- The report uses the Mahalanobis distance to measure industry crowding by analyzing the price and trading volume changes of industry indices over the past week[3][15] - The first quadrant represents industries with rising prices and volumes, while the third quadrant represents industries with falling prices and volumes. Points outside the ellipse indicate industries with a price and trading volume deviation confidence level exceeding 99%, signifying short-term significant crowding[15] - Last week, the beauty care and food & beverage industries showed significant trading crowding[3][16]
