Shrinkage decline refers to the decrease in trading volume, and the stock price or futures price temporarily falls back during the rising process. Shrinking back is a term in the stock or futures market. Shrinking back is usually considered as a technical adjustment. Due to the decrease in trading volume, it shows that the confidence of market participants in trading stocks or futures declines, so the price will temporarily drop, but this decline is usually temporary, because the market will re-accumulate energy and rise again after stepping back. Shrinking back, also known as "minor correction" or "correction", is one of the common adjustment methods in the stock or futures market.
