有这么几种解释：
Delta – the net share of equities investments. Delta describes the risk of a fund’s total position.

Delta/Exposure (%) – the percentage of a fund’s market value that has been invested in securities at the moment of review. If the fund’s delta is low, a large part of the fund capital has been invested in cash.

Exposure (delta) – the change in a fund’s asset value in relation to the fund’s total asset value assuming that all fund positions experience a simultaneous, equal change. Delta is calculated by dividing the delta-adjusted value of the fund with the total value of the fund.
