Two "doubling base" optical modules born in more than two months become important drivers.

In the recent momentum of the technology sector accelerating, two "doubling funds" have emerged since the second half of the year, with multiple products experiencing gains of over 90%. Among individual stocks, leading companies in the optoelectronics module sector such as Xin Yisheng, Zhongji Xuchuang, and Tianfutong Communication have continuously contributed to the net asset value of funds. In addition, companies like Shenghong Technology, which has increased more than sixfold since the beginning of the year, and companies like Yingwike that have doubled in the second half of the year, are also listed in the portfolios of many outstanding funds. After many individual stocks have doubled, fund managers have already raised concerns about the risks in the optoelectronics module sector. Some public fund experts point out that firstly, the market values of many "doubling funds" are currently at historical highs, and the risk of a short-term pullback should not be underestimated. Secondly, in terms of industry rotation, hotspots have been frequently shifting this year. If the sectors held by the funds enter a period of adjustment, the performance of the products will be more volatile. In addition, the issues of scale and liquidity should not be ignored. After the rapid expansion of the scale of some "doubling funds," the difficulty of allocation increases, the space for adjusting the stocks they heavily invest in is limited, and it may even restrict flexibility in future operations.
