Above its line on the last close.
How to read this
The red mark is the published kill line — the price that would prove the thesis wrong. The dot is where the name closed on 21 October 2026; a dot left of the mark has closed through its line.
Distance is drawn on a square-root scale, so close calls get the room. Past 8% a row reads well clear, with a hollow dot to show the figure is off the drawn scale. Rows run tightest first.
Kill line
A weekly close below $84, under RBC Capital's $85 target and MarketBeat's $86.33 consensus target. Negative third-quarter 2026 net client cash flows would also break the case.
Open pick Medium conviction, opened at $94.06. Since then +1.1% against the S&P 500's +1.2% (−0.1 pp). Kill line at open: $84.00 (weekly close); graded by at the latest.

How picks are graded →The thesis
Acadian Asset Management's rerating rests on ten straight quarters of client inflows lifting fees and margins. The third-quarter report on 29 October 2026 decides it. The case holds if third-quarter net client flows are positive, management fees reach at least the second quarter's $176.5 million, and the economic net income (ENI) operating margin stays at or above 40.3%.
The operating case has not changed since the 30 July 2026 second-quarter results. The only company news since then is the 14 October 2026 GlobeNewswire notice, which set the release for 7:30 a.m. Eastern Time on 29 October 2026 with a call at 11:00 a.m. The shares closed at $94.36 on 20 October 2026 in adjusted daily closes, up from $93.20 on 19 October 2026. That move brings the price closer to the high without adding evidence. The report still carries the case.
The narrative is maturing: Evercore ISI, Morgan Stanley and RBC Capital raised targets between 25 September 2026 and 9 October 2026, and none of them upgraded. The shares rose 17.7% over the three months to 20 October 2026, so the 29 October 2026 report has to confirm what the price already reflects. Unusual Whales lists a $1.25 third-quarter earnings per share (EPS) estimate from one analyst, below the second quarter's $1.33.
Bullish and bearish views on Acadian Asset Management Inc.
The bull case on Acadian Asset Management Inc. (AAMI), in brief: Flows have stayed positive for ten quarters. The bear case: Ratings have not followed the targets.
Bull case
- Flows have stayed positive for ten quarters. Acadian reported $4.3 billion of second-quarter net client inflows on the 30 July 2026 earnings call. That was its tenth straight quarter of positive flows and a 9% annualized organic growth rate.
- Fees grew with assets. The second-quarter 2026 Form 10-Q reported management fees of $176.5 million, up 44% year on year, and total revenue of $185.1 million, up 45.3%.
- Margin stepped up sharply. The ENI operating margin was 40.3% for the quarter ended 30 June 2026, against 30.7% a year earlier, according to the company's earnings presentation.
- Earnings beat the street last quarter. Second-quarter ENI diluted EPS was $1.33 against a $1.03 consensus estimate, a 29.1% surprise (company release; MarketBeat). The $1.25 third-quarter estimate listed by Unusual Whales leaves room for a repeat if fees held.
- The top analyst target sits above the high. Evercore ISI raised its target to $102 from $98 on 9 October 2026, above the $97.20 52-week high. Morgan Stanley moved to $95 from $81 on 25 September 2026 (Benzinga).
Bear case
- Ratings have not followed the targets. Evercore ISI (in-line), Morgan Stanley (equal-weight) and RBC Capital (sector perform) all kept neutral ratings while raising targets between 25 September 2026 and 9 October 2026. RBC's $85 target, raised from $80 on 9 October 2026, sits 9.9% below the $94.36 close of 20 October 2026.
- Consensus target trails the price. MarketBeat showed a hold consensus with an $86.33 target on 6 October 2026, from four hold ratings and one buy.
- Valuation screens rich on reported earnings. On 2 October 2026 MarketBeat listed a price-to-earnings ratio of 33.28 and a market value of $3.34 billion. Second-quarter ENI diluted EPS was $1.33, against $0.76 under generally accepted accounting principles (GAAP).
- Fees depend on market levels. The 30 July 2026 earnings presentation credited AUM growth to both market appreciation and positive flows. A weak equity quarter shrinks billable assets whatever clients do.
- Short sellers are adding. MarketBeat reported short interest at 3.90% of float on 2 October 2026, up 26.38% from the prior month.
Price setup
The shares closed at $94.36 on 20 October 2026, 2.9% below the $97.20 52-week high in adjusted daily closes. The 14-day relative strength index (RSI) stood at 58.1 that day, a reading short of the 70 level usually read as overbought. The three-month gain to 20 October 2026 was 17.7%.
Crowding evidence is mixed. Short interest rose 26.38% in the month to 2 October 2026, and MarketBeat recorded no insider purchases or sales in the 90 days before that date. Options pricing listed by Unusual Whales implies a move of about 8.94% around the report, which puts a large share of the near-term outcome on a single day eight sessions after the 20 October 2026 close.
Below the price, the analyst targets mark the nearest reference levels: MarketBeat's $86.33 consensus target and RBC Capital's $85 target. A weekly close below $84 would put the shares under both and erase most of the gain since the neutral-rated target raises.
Catalysts, next 30 days
- 29 October 2026 — Third-quarter 2026 results at 7:30 a.m. ET, call at 11:00 a.m. ET, confirmed by the company on 14 October 2026. Positive net client flows, management fees of at least $176.5 million and an ENI margin of at least 40.3% would extend the operating case. Negative flows would end the ten-quarter inflow run.
- ~5 November 2026, est. — Third-quarter 2026 Form 10-Q. The AUM roll-forward by strategy shows whether inflows were broad or concentrated in a few mandates.
What would change the view
The case breaks if third-quarter 2026 net client cash flows turn negative, ending the ten-quarter run reported through 30 June 2026. It also weakens if management fees fall below the second quarter's $176.5 million or the ENI operating margin drops below 40.3%, since either would show the fee and margin gains stalling.
On price, a weekly close below $84 would place the shares under RBC Capital's $85 target and MarketBeat's $86.33 consensus target. That would show the market siding with the neutral ratings. A downgrade from any of Evercore ISI, Morgan Stanley or RBC Capital after the 29 October 2026 report would point the same way.
What it trades with
Acadian's fees are set by quarter-end asset values, and the 30 July 2026 presentation credited part of AUM growth to market appreciation. The shares are therefore exposed to the direction of global equity markets alongside client flows. A broad equity drawdown would likely hit the shares and the following quarter's fee revenue together, so the stock offers little offset to an equity-heavy market move. Its company-specific driver is client flows into its systematic strategies, which is what the 29 October 2026 report measures.
Notes
- Acadian is the only remaining operating affiliate of the former BrightSphere holding company; price and filing history before the rename sits under the BSIG ticker.
- Economic net income (ENI) is a non-GAAP measure: Q2 2026 ENI diluted EPS was $1.33 against GAAP diluted EPS of $0.76, so quoted multiples depend on which measure is used.
- 35.49 million shares were outstanding as of 4 August 2026, with one holder at 16.4%; block trades can move the price more than the market value suggests.
- A $200 million term loan matures in October 2028; $172.5 million of the credit facility was undrawn at the Q2 2026 Form 10-Q.
- Fee revenue is tied to market levels: quarter-end asset values set billable AUM, so results lag equity drawdowns by about one reporting cycle.
