Asymmetric effects of trade risk on stock markets: Evidence in North America, Europe, and Asia
Bibliographic record
Abstract
This paper investigates how stock markets in North America, Europe, and Asia are exposed to tariff risks during the Trump first and second term presidency in the context of international trade uncertainty. Using the multivariable simultaneous quantile regression and data from January 1, 2017 to May 30, 2025, the paper examines daily and monthly responses of technology and energy stock markets to tariff risks using the US Trade Policy Uncertainty Index (TPU_US) and World Trade Uncertainty Index (WTUI). The sample covers the global market, Australia, Canada, China, France, India, Japan, Sweden, Taiwan, the United Kingdom, and the United States. The results indicate that trade risk exerts significant daily impacts on both technology and energy markets, with its varying effects across different market conditions. Specifically, in most markets, the impact transitions are from negative in lower quantiles reflecting bearish or unstable market conditions to positive in higher quantiles, associated with bullish market phases. This pattern suggests that US trade policy uncertainty tends to have a detrimental effect during periods of market stress, particularly harming technology and energy sectors. However, under favourable market conditions, such uncertainty may create opportunities for certain assets within these sectors to serve as effective hedges, potentially enhancing their attractiveness to investors during bull markets. This study timely contributes to the literature on the asymmetric effects of tariff risks on technology and energy stock markets at the global and national levels. Our findings offer practical implications for policy makers and investment practitioners that investing in technology and energy sectors can hedge against trade policy risks under bullish market conditions

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
