1. Quantitative follow-up means that in the stock market, investors can judge the trend of the stock and whether the stock price will rise or fall by quantifying the follow-up value.

2. Chip concentration refers to the degree of chip concentration of a stock, that is, the degree to which the chips of a stock are mastered by the dealer, which reflects the number of positions held by investors at different price points. Therefore, quantification and Zhuang value are not chip concentration.
