| 贝塔系数 （Beta） | The ultimate underlying’s raw beta at the ultimate underlying level (for reports with drill-down capability) and at the position level for stock positions. This means that for underlyings with both stock and option positions, the stock beta is displayed. Beta can be used to estimate the expected return on an asset given the return on a statistically related asset. | |
| Weight | The position weight used for the portfolio beta calculation (shown in the Risk Dashboard). | |
| Weighted Beta | The contribution of a given product to the total beta of your portfolio. | The total weighted beta value is also displayed in the "Portfolio Beta" field in the Risk Dashboard. |

The index-equivalent delta position for the stock. Calculation: Delta x dollar-adjusted beta (adjusted by ratio of close prices). |
The reference contract is displayed in the title of this field; this example uses SPX as the reference index. |
| SPX (Beta Weighted) Delta Dollars | This is a measure of the change in the position’s exposure in currency terms resulting from the change in the market (the reference contract). The Beta Weighted Delta Dollar reading multiplies the Delta * the position size to show the relative significance of any position translated in dollar terms and is the expected change in the value of the stock should the benchmark increase or decrease in value by $1.00 | |
| SPX (Beta Weighted) Delta Dollars % NLV | The ratio of the current beta weighted delta dollars to the portfolio's total net liquidity. | |
| Beta Delta Dollars | Exposure weighted by the unadjusted beta of the given position. For stocks, this is sometimes called the Beta-Adjusted Market Value. | |
