Ideas to research
The lists are built with concentrated-portfolio managers and count managers, not dollars.
Companies that meet objective criteria in the Q2 2026 13F filings of concentrated managers (a group defined by the shape of the portfolio, not by fame or results). Each one says why it is here. Ideas to research, not buy recommendations.
What our study found: buying, in equal parts, the stocks concentrated managers hold did not beat the S&P 500. Those they kept accumulating did somewhat better than the rest, and those nobody was accumulating did worse: a small gap, not enough to beat the index. See the study →
What it measures. It is a 0-to-100 score that ranks stocks on four data points from the 13F filings of concentrated managers: accumulation (40%: how many quarters in a row its holders, combined, have owned more shares; it maxes out at 4), conviction (30%: how much it weighs in their portfolios), net managers (20%: those who entered minus those who exited) and breadth (10%: how many hold it). The last three are the stock's standing against the rest (percentile). It subtracts 10 points if no manager added.
What it does not measure. It does not measure whether more managers are buying than selling or how many dollars moved, and it does not mean managers “agree”. A high score can sit alongside more managers trimming than adding (shown next to it, on each stock) and very few holders (5 are enough).
What the study says. Our own study supports only one of the four factors: accumulation. Conviction, net managers and breadth, which add up to 60% of the score, showed no reliable edge; they are there because they describe the holding, not because they anticipate returns. The weights were chosen looking at the study's same historical sample. It is an order to start researching, not a signal. See the study · Methodology
The highest scores. The score ranks by accumulation, weight in portfolios, net managers and number of holders: it does not mean more managers are buying than selling (each card says how many added and how many trimmed).
“Net flow”: shares concentrated managers added minus those they cut in the quarter, in dollars, at the 13F quarter-end implied price, not each trade's price. It is not part of the score.
