Beta shows to what extent a portfolio moves in line with the market. But how well do investors really understand this relationship?

Large language models may seem brilliant at making predictions, but often it’s just memorization. And that has implications for investors relying on LLMs for economic analysis.

The decline of value investing is not a recent phenomenon but a process that has been unfolding for over three decades. While many pinpoint its loss of effectiveness around 2007, Baruch Lev and Anup Srivastava demonstrate in their study that the strategy has in fact been structurally underperforming since the late 1980s.

The wine world was taken by surprise in 1976: Steven Spurrier, the British wine merchant, had a jury of experts taste a series of French and American wines blind. To everyone’s surprise, the United States won gold twice in the categories of Chardonnay (California vs. Burgundy) and Cabarnet Sauvignon (California vs. Bordeaux).
