本研究探討私募折價幅度及私募前後績效之影響因素，並將應募人分為內部人、積極投資人以及消極投資人三種，觀察不同應募人下的私募，其私募前及私募後是否有累計異常報酬。
實證結果發現，在私募前股價表現與私募對象之關係方面，當私募對象為內部人時，在私募前45日股價即開始下挫，之後的累計異常報酬皆為負值，其原因可能為內部人藉由套利交易，先行在集中市場上賣出手中原有持股，再用較低價格認購私募新股，此舉不但能使手中持股的成本降低同時也能維持既有股權。關於私募半年後的股價表現，內部人及積極投資人私募後的累計異常報酬顯著為正，代表內部人在投資私募新股時，可能隱含著未來公司有較好的投資機會；至於積極投資人後續績效為正，可能代表積極投資人未來將會扮演監督者的角色，有助於提高公司的價值。迴歸分析也顯示，當公司私募的價格相對於公司在私募定價日當時的股價折價越多時，私募之後的累計異常報酬越低，代表私募折價會降低公司價值，傷害現有股東的權益。 / This study investigates the effect of private placements on stockholder wealth before/after the events based on cumulative abnormal return for three categories of investors, namely, the insiders, active investors and passive investors.
For private placements with insider investors, significant negative abnormal return prior to private placements may reveal sell arbitrage taken by insiders while significant positive abnormal return subsequent to private placements supports signaling theory.
Evidence showing significant negative relation between price discount on private placements and subsequent business performance implies the price discount reduces market value and hence harmful to existing shareholders’ wealth.
