近年來隨著科技的發展與金融市場的開放，越來越多人開始參與交易投資，特別是在COVID-19期間，由於全球經濟不穩定和股市波動較大，許多人轉向投資股票市場，台灣股市交易量更是創下歷史新高。在這樣的背景下，如何制定一個有效的交易策略，成為投資者關注的重要議題。
一目均衡表是一種被廣泛運用於金融市場的技術分析方法，可以幫助投資者判斷股價趨勢、支撐位和壓力位，從而制定交易策略。本研究利用一目均衡表制定了交易策略並進行模擬交易，採用統計方法檢驗該策略是否能獲得超額報酬，打敗買進持有台灣50的交易策略。本研究以台灣50成分股作為樣本，蒐集了自2020年12月15日至2022年12月30日的數據。研究結果如下：運用遲行線的一目均衡表交易策略以及加入價格緩衝帶機制後的調整後策略，皆能在統計上顯著產生超額報酬，顯示一目均衡表交易策略在台灣股票市場上是有效的。此外，當調整後策略在價格緩衝帶5%至10%時，可以進一步提升交易績效，其報酬率在統計上顯著優於原始策略。

In recent years, with the development of technology and the opening of financial markets, more and more people have started to participate in trading and investment, especially during the COVID-19 pandemic. Due to global economic instability and stock market volatility, many people have turned to investment in stock market, and the trading volume in the Taiwan stock market has reached a historical high. In this context, how to develop an effective trading strategy has become an important issue for investors.
The Ichimoku Cloud, a widely-used technical analysis method in financial markets, can assist investors in determining stock price trends, support and resistance levels, and thus formulate trading strategies. This study used the Ichimoku Cloud to develop a trading strategy and conducted simulated trades. Statistical methods were used to examine whether the strategy could achieve excess returns and outperform the buy-and-hold Taiwan 50 trading strategy. This study collected data on component stocks from the Taiwan 50 index from December 15, 2020, to December 30, 2022. The results showed that the Ichimoku trading strategy using the Chinkou Span and the adjusted strategy with a price buffer mechanism could both significantly produce excess returns statistically, demonstrating the effectiveness of the Ichimoku trading strategy in the Taiwan stock market. Furthermore, when the adjusted strategy had a price buffer of 5% to 10%, it could further improve trading performance, and its return on investment was statistically significantly better than the original strategy.
