James O’Shaughnessy’s Cornerstone Value Strategy: Unearthing High-Quality Gold Mines in Large Cap Revenue Stocks
James P. O’Shaughnessy demonstrated in his book What Works on Wall Street that market returns do not fully conform to the Efficient Market Theory, showing that selecting stocks with low P/B, low P/CF, and low P/S ratios significantly enhances long-term returns. Among his methodologies, the “Cornerstone Value Strategy” targets high-revenue, cash-rich large-cap stocks. It screens equities across four dimensions—size, cash flow quality, revenue scale, and relative valuation—and uses dividend yield ranking for final selection. Applying this strategy to the Taiwan stock market (excluding financial sector) with six quantitative filters and an annual July rebalancing protocol validates its capacity to deliver sustained alpha by balancing deep value with high shareholder yield.

Empirical Research on Behavioral Factors in the Taiwan Stock Market: A Case Study of the Share Distribution
In an AI-driven Taiwan stock market, mastering chip distribution (ownership structure) is the key to profitability. This study delves into the Share Distribution data from the TDCC, transforming 15 tiers of shareholding data into behavioral finance factors such as investor attention, opinion dispersion, and retail speculation. By utilizing Fama–MacBeth two-stage regression and the alphalens-tej quantitative tool, we precisely validate the predictive power of psychological biases on stock returns, providing investors with actionable Alpha strategies and robust risk management solutions.

Empirical Study on TESG Rating: The Relationship between Corporate ESG Performance and Bank Lending Decisions
This article examines how corporate ESG performance affects bank lending decisions in Taiwan. Using TEJ’s TESG Ratings, the study finds that companies with stronger ESG performance generally receive more favorable lending conditions, including lower loan spreads, larger loan amounts, longer maturities, and a lower likelihood of collateral requirements. The findings also highlight the importance of balancing ESG initiatives with financial performance, as excessively high or low ESG performance may lead to less favorable lending terms.

How Information Sources Shift Stock Prices: Empirical Evidence from TCRI Watchdog
TCRI Watchdog (WD) converts complex news and announcements into standardized quantitative alternative data. Building on our research into “Official Announcements (Source P)” and “Media News (Source N),” we have confirmed that disclosure channels directly dictate the speed and structure of market digestion. This chapter moves from macro “Event Categories” to micro “Source × Sub-category” dimensions to capture actionable Alpha within granular events. Focusing on high-sensitivity “Corporate Control Events,” we analyze the signal heterogeneity between Source P and Source N. We further demonstrate how these high-precision signals assist investors in optimizing entry timing and hedging strategies.

From News to Markets: Investment Signals from Media Coverage (Part II) — An Empirical Analysis of TCRI Watchdog “N News Media” Events
While Part I establishes that news events generate identifiable market reactions, the informational content of news varies widely—from industry developments and financial disclosures to management changes and corporate crises. Event intensity alone is insufficient to explain these differences. Accordingly, this section decomposes news events into five categories (A, I, M, F, R) and examines whether markets respond systematically differently across news types.

From News to Markets: Investment Signals from Media Coverage (Part I) — An Empirical Analysis of TCRI Watchdog “N News Media” Events
Introduction: News as an Event-Based Market Signal In today’s highly real-time and information-saturated markets, news media no longer merely serve as post-hoc explanations of price movements. Instead, they have become a critical channel through which market expectations are formed and sentiment spreads. Compared with structured disclosures such as regulatory penalties or official disclosures via the […]

Factor Research – The SIR Short-Selling Factor: Extracting Negative Signals from Institutional Borrowing Activity – SIR Part 1
Taiwan’s short-selling signals are often misleading because the market operates under a dual-track system: retail investors short stocks through margin accounts, while institutional investors use securities borrowing and lending (SBL). Only SBL-based short selling reflects informed institutional sentiment, while margin shorting introduces noise. This study isolates SBL to construct the Short Interest Ratio (SIR) and evaluates its ability to predict cross-sectional returns and reveal size-dependent patterns in informed short-selling behavior.

Factor Strategy – Applying SIR to Strengthen Momentum Strategies in the Taiwan Market – SIR Part 2
This study examines whether incorporating the Short Interest Ratio (SIR) can improve the performance of a 52-week high momentum strategy in Taiwan. By comparing a baseline momentum model with two SIR-enhanced versions—one using SIR as a filter and another integrating it into a composite score—we find consistent gains in returns, lower volatility, and reduced drawdowns. The results show that SIR strengthens momentum strategies by identifying stocks under institutional short-selling pressure.
