Abstract: 本研究運用選擇權隱含之 Beta 值,探討市場危機是否具可預測性。本研究 搜集了 1996 年至 2016 年 S&P 500 股價指數與其成分股週資料,以 S&P 500 股 價指數月報酬率之風險值定義市場危機,並由選擇權隱含之 Beta 值定義三項代 理變數,使用決策樹模型對市場危機進行預測。實證結果發現,在相對寬鬆之 風險值下,決策樹模型較能夠正確預測市場危機以及 S&P 500 股價指數下跌之 趨勢。
This study investigates whether market crashes can be predicted using option- implied betas. Three proxy variables of option-implied betas as features are used to predict market crisis event which is defined using Value at Risk(VaR). The thesis empirical results based upon 1996-2016 S&P 500 data show that market crisis event and S&P 500 index movement could be predicted more accurately when using VaR with a lower confidence level.
