摘要 本研究以臺灣股票市場為研究對象,探討將國家發展委員會(國發會)所編製之景氣對策信號納入投資決策,是否能在不同投資風格下有效改善投資組合之風險與績效表現。研究核心在於比較市值型指數投資與動能型投資於景氣循環擇時架構下之差異,並進一步檢驗不同景氣燈號門檻設定對投資績效之影響。 研究方法上,本研究以元大台灣50 ETF(0050)作為市值型投資之代表,並依據 George & Hwang(2004)所提出之 52 週高點(52-week high)動能指標,建構動能型股票投資組合。在投資策略設計上,分別建立買進並持有之基準策略,以及結合景氣循環擇時機制之投資策略,並設定兩組具代表性之景氣燈號門檻(16/38 與 22/32)作為比較基礎。研究期間涵蓋 2003 年至 2025 年之長期樣本,以確保實證結果能反映多次完整景氣循環。 實證結果顯示,在市值型 ETF 與動能投資組合中,引入景氣循環擇時機制皆能有效改善投資組合之風險結構。其中,以官方景氣燈號分界為基礎之策略(16/38)在波動度、最大回撤與風險調整後績效指標(Sharpe Ratio、Calmar Ratio)上,均明顯優於較為寬鬆之門檻設定(22/32)。相對績效分析結果亦顯示,景氣循環擇時策略的主要效果在於降低市場系統性風險曝險(Beta),而非作為主要超額報酬之來源。 此外,研究結果指出,動能投資組合在整體報酬與風險調整後績效上,顯著優於市值型 ETF,顯示長期投資績效主要來自動能溢酬,而景氣循環擇時策略則扮演風險管理與資產配置輔助之角色。整體而言,景氣循環擇時策略並非用以追求最高長期報酬,而是在可接受的報酬犧牲下,有效重塑投資組合之風險結構,對於風險控管導向之投資人具備實質應用價值。 本研究補足臺灣市場在「景氣循環 × 市值型 ETF × 動能投資策略」整合性實證分析之研究缺口,並為景氣狀態依賴型投資策略提供具體且可重現之實證證據,對學術研究與實務資產配置皆具有重要參考意義。
This study examines whether incorporating the Business Cycle Monitoring Indicator published by Taiwan’s National Development Council (NDC) into investment decision-making can effectively improve portfolio risk and performance across different investment styles in the Taiwan stock market. The core objective is to compare market-capitalization–based index investing and momentum-based investing within a business-cycle-based timing framework, and to further evaluate how alternative business-cycle threshold settings affect investment performance. Methodologically, this study employs the Yuanta Taiwan 50 ETF (0050) as a representative market-capitalization investment vehicle, and constructs momentum-based stock portfolios using the 52-week high momentum indicator proposed by George and Hwang (2004). The strategy design includes both buy-and-hold benchmark strategies and business-cycle timing strategies. Two representative sets of business-cycle signal thresholds (16/38 and 22/32) are implemented for comparative analysis. The sample period spans from 2003 to 2025, covering multiple complete business cycles to ensure the robustness of empirical results. Empirical findings indicate that incorporating business-cycle-based timing mechanisms improves the risk structure of portfolios in both market-capitalization ETFs and momentum-based portfolios. Among the examined strategies, the threshold setting aligned with the official business-cycle signal classification (16/38) consistently outperforms the more flexible threshold design (22/32) in terms of volatility reduction, maximum drawdown control, and risk-adjusted performance measures such as the Sharpe ratio and Calmar ratio. Results from relative performance analysis further suggest that the primary contribution of business-cycle timing lies in reducing systematic market exposure (beta), rather than serving as a dominant source of excess returns. In addition, the results demonstrate that momentum-based portfolios significantly outperform market-capitalization ETFs in terms of overall returns and risk-adjusted performance, indicating that long-term performance is primarily driven by momentum premiums. In this context, business-cycle timing strategies function mainly as risk management and asset allocation tools rather than return-maximizing mechanisms. Overall, business-cycle-based timing strategies are not designed to achieve the highest possible long-term returns, but rather to reshape portfolio risk profiles at an acceptable cost to expected returns, offering practical value for risk-conscious investors. This study contributes to the literature by filling a gap in integrated empirical research on business cycles, market-capitalization ETFs, and momentum-based investment strategies in the Taiwan Stock market. It provides reproducible and policy-relevant evidence on state-dependent investment strategies, with meaningful implications for both academic research and practical asset allocation.
