Tradingmanagement are indirectly funded by using balance sheet cash. Hypothesis testing with the empiricalmodel 1 was to confirm the role of CashRatio as the moderating variable that interact DER to affectIPO underpricing which originally was not. The findings support the predictions that interactivevariable DER*CashRatio affect IPO underpricing. A managed trading had a non negative profitsconstraint so that selective post-IPO trading was conducted to cause trading imbalance observableas skewed trading volume (Skewness). Subsequent tests with the empirical model 2 was to confirmthe role of Skewness as the moderating variable that interact VolRatio to affect post-IPO stockreturn (RGM) which originally was not. The findings support the predictions that interactive variableLnVolRatio*Skew affect RGM.
