Abstract

The analysis of time series graph shows a linear trend between Consumer Price Index (CPI) and Money Supply Index (M2I) whereas a nonlinear trend with stock prices. Moreover, the graph also shows an unequal spread with the stock prices, which indicate Heteroskedasticity. Then, descriptive statistics test shows high Standard Deviations for stock prices compared with CPI and M2I, which indicate a higher volatility in stock prices. Finally, the hypothesis test for equality of variance concluded the presence of Asset Price Bubbles by rejecting null hypothesis of equal volatility against the alternative hypothesis of greater volatility in stock prices.
