A Texture‐Free Multi‐Scale Model for Surface‐Based Rendering of Knitted Fabrics
Abstract Knitted fabrics present unique challenges for realistic rendering due to their complicated structure and scale‐dependent appearance. Existing methods typically rely on explicit yarn geometry, which is computationally complex, or texture‐based representations that require heavy storage and precomputed maps. In this paper, we introduce the first

From Regression to Reasoning: Predicting M&A Announcement Returns With Large Language Models
ABSTRACT This study investigates whether large language models (LLMs) can predict short‐term market reactions to M&A announcements. We prompt OpenAI's latest reasoning models (o3, GPT‐5, and GPT‐5.1) to forecast whether the combined market value of acquirer and target will increase or decrease, drawing on deal‐, firm‐, and macroeconomic data for large ...

ABSTRACT This paper shows that for firms in Pacific time zone of the United States, the effect on weekly returns from overnight returns would be 23% stronger than firms in Eastern time zone. This asymmetrical impact is documented to be associated with degrees of information transparency due to firm's different timings of information releases.

Measuring Thematic Funds Performance via an Approach Based on Observable and Latent Factors
ABSTRACT This paper investigates whether thematic equity funds deliver abnormal performance relative to conventional global equity funds. Using Fama‐French models augmented with latent factors, we estimate fund‐level alphas, and apply the false discovery rate methodology to an estimated three‐group mixture distribution, separating good, null and bad ...

Decoding Information Flow in Fund Families: Evolution, Drivers and Impacts
ABSTRACT This paper proposes a new measure of information sharing within fund families inferred from trading activity and examines its evolution and managerial drivers. The findings reveal a declining trend in internal information exchange over time, with higher information flow in families characterized by greater managerial interaction.

A U‐Shaped Flow–Performance Sensitivity Across the Globe
ABSTRACT Using a worldwide sample of equity mutual funds, we document a new stylized fact: the flow‐performance sensitivity (FPS) is greater for both bottom and top performance, compared to the middle. This “U‐shaped” FPS is especially strong in down markets, for small/mid‐cap funds, and in the latest decade. These results hold over quarterly or yearly

Project valuation and investment decisions: CAPM versus arbitrage [PDF]
This paper shows that (i) project valuation via disequilibrium NPV+CAPM contradicts valuation via arbitrage pricing, (ii) standard CAPM-minded decision makers may fail to profit from arbitrage opportunities, (iii) standard CAPM-based valuation violates ...

Explanations for Cross‐Sectional Return Anomalies: Evidence on the IVOL Puzzle
ABSTRACT Considering the time‐series dimension alongside the cross‐sectional dimension helps to almost entirely account for the idiosyncratic volatility (IVOL) puzzle. Based on a purely cross‐sectional approach, the previous literature shows that numerous candidate theories collectively fail to explain the puzzling finding that high‐IVOL stocks ...
