Group 1 - The core concept of the article revolves around the importance of the deviation degree of money market funds as a risk indicator, alongside traditional yield metrics like the 7-day annualized yield [1][3] - The deviation degree is calculated using the formula: (shadow pricing net value - amortized cost net value) / amortized cost net value * 100%, indicating the difference between market value and book value of the fund's assets [2][3] - A positive deviation indicates potential unrealized gains, while a negative deviation suggests unrealized losses, which could materialize during redemptions [3][4] Group 2 - Fund managers are required to calculate the deviation degree on each valuation day, and if the absolute value exceeds certain thresholds, they must take specific actions and disclose information accordingly [3][4] - The thresholds for deviation degree are set at 0.25% and 0.5%, with corresponding actions required from fund managers to mitigate risks [4] - Investors can find deviation degree information in the fund's quarterly, semi-annual, and annual reports, specifically in the "Investment Portfolio Report" section [5][6] Group 3 - A specific fund's quarterly report indicated that the absolute value of the deviation degree was between 0.25% and 0.5% for 0 times, with a maximum deviation of 0.1600% and a minimum of 0.0228% [7] - The average absolute value of the deviation degree for each working day during the reporting period was 0.0854% [7] - Overall, the deviation degree serves as a crucial indicator for investors to gauge potential valuation volatility risks in money market funds, with short-term deviations being a normal occurrence [8]
