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 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.

Impulse MACD Futures Trading Strategy
LazyBear is a highly influential indicator developer on the internationally renowned trading platform, TradingView. He has created a large number of popular custom technical indicators, and his open-source code has inspired countless quantitative traders and technical analysis enthusiasts around the world. LazyBear’s indicators often focus on reducing the lag of traditional indicators and incorporate unique market observations to better capture trends and momentum. One of his representative works, the “Impulse MACD,” is adopted here. This indicator is not a traditional Moving Average Convergence Divergence (MACD), but rather a significantly improved version. It uses a zero-lag Double Exponential Moving Average (DEMA) to respond more quickly to price changes and combines a smoothed high-low price channel (SMMA) to determine market “impulse.” The core idea is that trading signals are more valuable only when price momentum aligns with the trend direction. This helps to filter out some of the noise typically found in ranging markets.

Golden Cross Futures Trading Strategy（MTX）
The concept of the Moving Average (MA) originates from the Dow Theory developed in the early 20th century. Dow Theory emphasizes that markets exhibit trends, and such trends can be observed through price movements themselves. From the Simple Moving Average (SMA) and Exponential Moving Average (EMA) to more sophisticated variants such as the Double Exponential Moving Average (DEMA) and Hull Moving Average (HMA), all these improvements aim to address the inherent lag problem of traditional moving averages, allowing them to reflect price trends more quickly or more smoothly.

When Others Fear, I Enter: Anthony Melia’s Contrarian Strategy for Winning in the Market
In financial markets, Contrary Thinking is a timeless strategic wisdom. It stems from a simple yet profound observation: when most people are overly optimistic, the market is often overheated; when the crowd falls into fear, it may actually present a buying opportunity. However, contrarian investing has long remained at the level of a proverb, lacking concrete and quantifiable standards of action, making it difficult to implement in practice.
