description: "$TOPNC(07688.HK) rose +13.5%, with trading volume expanding to over four times the average. The driver is the collective surge in Hong Kong stocks' commercial aerospace concept—the capacity story of five-axis machine tools connecting commercial aerospace and large aircraft has been brought up again. In the rotation of concepts, these equipment suppliers always follow the rise, but order fulfillment has never kept up with the speed of the hype. Will the capital in this aerospace concept stay longer this time? The signal I'm observing is the trading volume: if the volume shrinks back within three days, it's the same old story."
