During periods of volatility in the A-share market, multiple channels of incremental funds have entered the scene, including significant inflows into ETFs, rapid position-building by newly launched funds, dense ( dense is left as is since it seems to be part of a proper noun or context not fully translated in the raw text, but assuming it's describing 'frequent' actions, I'll adjust the sentence meaning accordingly in the translation) frequent self-purchases by public and private funds, and the lifting of purchase restrictions by high-performing funds. Industry insiders believe that such contrarian operations play a supportive role in the market, indicating that institutional funds recognize the allocation value at the current market levels. Some fund managers stated that the short-term correction in the technology sector is normal, and its long-term performance remains promising.
