實證結果顯示，本研究的9種策略中，皆展現良好的績效報酬。此外，若將9種策略中最差績效的策略與大盤指數、公會評比基金以及Brock等三人的技術分析方法做比較，最差績效策略明顯優於其他三種，因此，本研究策略可以作為投資人未來決策的考量。 ;This study attempted to capture the peak and bottom of Taiwan Stocks Index from the prospect of probability. It was aimed at buying the shares when the index slumped badly and then selling them back to the market when the index was in its peak as a breakthrough point. Moreover, the study was referred to as the “victory probability,” which developed 9 strategies of probability and implemented practical simulation of back testing on history weighted stock indexes over the past 11 years. The results of back testing were then compared with Taiwan Stocks Index, Association Rating Fund and technical analysis of BLL to learn if the performance of the study was better than the other three so as to serve as a trading strategy for investors’ reference in the future. Empirical evidence proved all 9 strategies proposed in the study showed great performance. In addition, if compared the strategy with the worst performance with Taiwan Stocks Index, Association Rating Fund and the technical analysis of BLL, even the strategy with the worst performance was the best of all. As a consequence, strategies proposed in this study can be seen as guidance for investors to make decisions in the future.
