Shadow price means that the fund manager uses market interest rates and transaction prices to re-evaluate the valuation objects held by the fund on each valuation day.

When the deviation between the fund's net asset value and the shadow price reaches or exceeds 0.5% of the fund's net asset value, or when the fund manager believes that other major deviations have occurred, the fund manager may make adjustments after agreement with the fund custodian to bring the fund's net asset value to

It can more fairly reflect the value of fund assets and ensure that the net asset value of the fund calculated using the amortized cost method will not cause substantial damage to fund holders.

Shadow price reflects the marginal contribution of resources to the objective function.

That is, the efficiency of converting resources into economic benefits.

Shadow prices reflect the scarcity of resources and their marginal use value.

Shadow prices are the prices of various types of bonds calculated by fund companies based on estimated market yields, reflecting the price levels of bonds held by money market funds under existing market conditions.

Fund companies routinely use the cost amortization method to calculate net asset value, that is, valuation based on the historical cost of bonds and amortized premiums and discounts.

If there are major changes in the market, there will be a big difference between the shadow price and cost amortization method valuations.

When the deviation between the two is large, the fund company should adjust the portfolio according to the situation to control risks.

A price calculated using the linear rule method that reflects the optimal use of resources.

Use calculus to describe the shadow price of resources, that is, when the resource increases by an amount and a new maximum value of the objective function is obtained, the ratio of the increment of the maximum value of the objective function to the increment of the resource is the objective function's response to the constraints (i.e., resources)

The first-order partial derivative of .

When using linear programming method to solve the optimal utilization of resources, that is, in the process of solving how to maximize the total output of limited resources, the corresponding minimum value is obtained. The solution is the dual solution, and the minimum value is used as the economic evaluation of the resource.

, expressed as shadow price.
