金融控股公司從事衍生性金融商品交易對其績效影響之研究

The Effect of Financial Derivatives Trading on BHCs' Performance

指導教授 : 陳若暉 李卿企

摘要


本文的研究目的為估計金融控股公司從事衍生性金融商品交易對其績效的影響。由於金控公司在衍生性金融商品市場的交易動機不同於一般公司僅以避險為目的,其動機尚包含避險與投機交易,故本研究針對不同的交易的動機將樣本作適當的分類,第一類樣本,即金控公司從事衍生性金融商品操作的動機純粹是避險與完全沒有從事衍生性金融商品交易的金控公司進行比較,第二類樣本,即金控公司從事衍生性金融商品交易的目的是避險加上交易,而並非純粹避險,稱之為「非純粹避險金控公司」與「完全無交易之金控公司」之比較,並利用「傾向分數配對法」將樣本重新配對,以解決過去文獻在估計上所產生的選擇偏誤問題。 研究結果發現隨著金控公司的交易動機不同,其對金控公司績效變數ROA與ROE的影響會有截然不同的結果。如果其交易目的是以避險為主,比較配對後金控公司與未經配對的樣本的估計結果,發現以衍生性金融商品進行避險對金控公司績效的影響係數上有顯著的提升,並同時發現,在未經「傾向分數配對法」配對之前的樣本有低估金控公司以衍生性金融商品避險的效果,顯示避險確實可以大幅提升金控公司的績效。然而如果其交易目的非純粹是以避險為主,其從事衍生性金融商品交易會使其ROA無顯著的影響。結果證實金控公司從事衍生性金融商品的背後動機對公司的績效表現影響甚鉅。

並列摘要


The purpose of this paper is to estimate the effect of financial derivatives trading on the performance of bank holding companies(BHCs). As we know the motivations of financial derivative trading by the BHCs could be classified either “hedge” or “speculation”. We further separate the sample into two difference groups with different motivations to examine whether the effect would be different under different trading motivations. We also use “Propensity Score Matching Method” to re-estimate the model to solve the selection bias problem. We use the ROA and ROE as proxy variables for BHCs’ performance. We find BHCs can improve their performance by hedging with financial derivatives. Nevertheless, if the motivation of financial derivatives trading is not “completely hedge” there is no significant relation between performance and the use of derivatives. Consequently, our evidence does support that the trading motivations of financial derivatives trading play an important role on the performance of financial institutions.
