Dongyue Group's stock plummeted 5.53% during intraday trading on Monday, extending its recent downward trend.

The decline is attributed to continued profit-taking pressure as domestic refrigerant prices have shown signs of stagnation after reaching near-decade highs. The stock had accumulated massive gains since late May, with year-to-date gains approaching 90%, surpassing multiple institutional target price ranges.

Short-term valuation has overshot the pricing-in of refrigerant price increases, and market willingness to lock in profits at elevated levels remains strong, leading to the sell-off.
