# Open a "supermarket" to buy high and sell low; there are ways for retail investors to engage in short-term speculation

From 2020 to 2021, during the structural market trend of "drinking and taking medicine," the "30-day fund trading method" became popular among fund investors, which involved using funds for short-term trading, following trends to buy hot products, and engaging in high selling and low buying of funds with a 30-day redemption fee waiver. Later, this strategy further evolved into the "7-day fund trading method," closely following market hotspots and selling as soon as profits were made. Since the beginning of this year, the equity market has been booming, with a prominent structural trend in technology and a plethora of segmented hotspots emerging, leading to the resurgence of the previously dormant short-term fund trading strategy. Fund investors are keen on speculating on popular fund Class C shares in technology, gold, and other sectors. In the third quarter, several high-performing technology-themed funds saw their net values surge and experienced inflows of capital, resulting in a tenfold increase in scale. Interestingly, some of these funds had subscription and redemption amounts in the tens of billions, indicating a new trend where some fund investors treat these actively managed funds as stocks for "short trading."
