&#34;When others are fearful, I am greedy; when others are greedy, I am fearful.&#34; — Warren Buffett
Since the beginning of this year, the A-share market has experienced significant fluctuations. On March 23, the CSI 300 fell by -3.26%, with nearly 5,200 stocks closing down; on March 24, the market rebounded again, with the CSI 300 rising by 1.28%. Should we stay or leave the equity market now? Instead of worrying about the next market trend and opportunities, let's take a look at the &#34;quality&#34; selection of equity allocation in a volatile market — the CSI 300 Quality Index (932431.CSI), which has outperformed the CSI 300 Index by 37 percentage points over the past decade and by 1.1 percentage points this year.

Quality selection based on profitability
Warren Buffett once said, &#34;If I could only use one indicator to select stocks, I would choose ROE.&#34;
Return on Equity (ROE) can comprehensively assess a company's profitability and its ability to &#34;make money with shareholders' money.&#34; The compilation logic of the CSI 300 Quality Index goes further on the basis of ROE, incorporating the stability and quality of earnings of listed companies, selecting 50 true &#34;profitability stars&#34; from the constituents of the CSI 300 Index.
