AMG Reports Monday: Bulls See 30% EPS Growth, Bears Eye Fee Pressure

Affiliated Managers Group reports Q3 2026 results on November 2, with the stock up 8.4% over the past month to $399.02 and analysts carrying a mean price target of $523, implying roughly 31% upside from current levels.

Options positioning is notably relaxed into the print. The put/call ratio stands at 0.41, just below its 20-day average of 0.43 and well off its 52-week high of 1.71. That reading sits 0.6 standard deviations below the recent mean, suggesting call activity is dominating the options market rather than defensive hedging. Short interest reinforces the benign picture: at 3.2% of the free float, it has fallen 6.2% over the past week and borrow conditions are extremely loose, with availability running at roughly 7,456% of outstanding short interest. Cost to borrow is 0.47%, near its lowest in recent months. There is no meaningful short squeeze pressure, and no evident speculative build against the stock heading into the release.

The bull case rests on AMG's affiliate model and management's own 2026 guidance for earnings growth above 30% year on year. The company reported $942.4 billion in AUM at the end of June, with private markets at 16% and liquid alternatives at 31% of that total, a mix that is more resilient to passive-versus-active headwinds than a pure traditional-equity shop. TD Cowen's Bill Katz raised his target to $523 on October 12, keeping a Buy. Goldman Sachs lifted its target to $341 in January, though that note is now nine months old and the stock has since moved substantially higher, so the Goldman figure should be read as directionally positive rather than a current-price anchor. Bears point to the structural pressure on active equity fees, the risk that alternatives flows disappoint, and the leverage AMG's earnings have to broad market levels: a material drawdown in capital markets would compress fee income quickly across the $942 billion platform. EPS momentum factor scores of 76 (30-day) and 82 (90-day) show estimates have been moving up, but the 12-month forward year-on-year EPS growth rank sits at just 23, reflecting the Street's skepticism about whether the 2026 surge repeats.

Retail attention to AMG has picked up ahead of the print: Wikipedia views data from the Wikimedia Foundation showed a z-score of 1.45 on October 22, above its own 90-day baseline. The dataset is not a measured lead for AMG's revenues, so it carries no direct read-through to the quarterly figures, but the elevated interest is consistent with the stock approaching a multi-year high.

One ownership note is worth tracking. Vanguard's two separate entities, Vanguard Portfolio Management and Vanguard Capital Management, together filed new 13G schedules in April 2026, each reporting stakes just above 5%, while the consolidated Vanguard Group entity separately disclosed its stake had dropped to zero. The net Vanguard position across these entities is not straightforward to net from public filings alone. Separately, Millennium Management reduced its 13G stake from 5.3% to 3.6% as of its October 2025 filing, and Clarkston Capital dropped from 5.2% to 3.2% by February 2026. The CEO, Jay Horgen, sold 17,500 shares at roughly $338 in an open-market transaction on June 8, the only clean discretionary sale in the recent filing history, though the 90-day net insider position also reflects tax-withholding disposals tied to stock awards.

The November 2 release will test whether AMG's Q3 fee revenue and private markets growth are tracking toward the full-year earnings target management set out, and whether organic flow trends in alternatives have held up against an active equity industry still losing ground to passive strategies.
