Abstract
Financial markets have witnessed a dramatic shift in financial flows in recent years from Active fund management where professional investors attempt to beat the market (generate ‘alpha’) to Passive investment where portfolios are assembled that follow existing market indicators (track ‘beta’). This transition has important implications for both corporate governance and wider society, with potentially significant distributive effects. Passive investing is predicated upon different bodies of knowledge and is suggestive of an epistemic shift of sorts in financial markets. In such circumstances, field theory suggests that incumbent groups like Active players will try to adapt to the new rules of the investment game. However, drawing from an empirical study which explores the views of the Active investment community in both the United Kingdom and the United States, we document significant defensiveness vis-à-vis the rise of Passive investing. Whereas behavioural approaches might explain this defensiveness in terms of irrationality, the conceptual approach advanced here instead emphasizes the epistemic opportunism (convoluted and self-serving attempts to demonstrate superior knowledge) that communities strategically engage in to justify their position. As such, we conclude that financial markets should be understood as constituted by slowly evolving communities of practice whose habits, routines and ways of knowing can be difficult to shift, even when faced with overwhelming evidence that what they are doing doesn’t work most of the time.

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 it
