The analysis of the variation trend for each stock index with daily reported case number is presented as four figures: figure (a) presents the effect of daily reported number of H7N9 cases on the log-transformed opening price of the Avian Influenza Sector Index(3D); figure (b) presents the same information as figure (a) but transformed into planar form; and figures (c) and (d) present the effects on closing prices. From figure 3D, we could observe the lagged effects on stock indices for one and two days after the reporting of confirmed H7N9 case numbers. In planar form, we observe the variation trend for the various stock indices along with daily reported number of confirmed H7N9 cases. Here, above the X axis denotes an increasing log stock price, while below the X axis denotes a decreasing log stock price. The absolute value of the distance from the X axis represents speed of change.
