At Holdings Channel, we have reviewed the latest batch of the 56 most recent 13F filings for the 03/31/2026 reporting period, and noticed that American Express Co. (Symbol: AXP) was held by 24 of these funds. When hedge fund managers appear to be thinking alike, we find it is a good idea to take a closer look.
Before we proceed, it is important to point out that 13F filings do not tell the whole story, because these funds are only required to disclose their *long* positions with the SEC, but are not required to disclose their *short* positions. A fund making a bearish bet against a stock by shorting calls, for example, might also be long some amount of stock as they trade around their overall bearish position. This long component could show up in a 13F filing and everyone might assume the fund is bullish, but this tells only part of the story *because the bearish/short side of the position is not seen*.
Having given that caveat, we believe that looking at *groups* of 13F filings can be revealing, especially when comparing one holding period to another. Below, let's take a look at the change in AXP positions, for this latest batch of 13F filers:
In terms of shares owned, we count 5 of the above funds having increased existing AXP positions from 12/31/2025 to 03/31/2026, with 14 having decreased their positions.
Looking beyond these particular funds in this one batch of most recent filers, we tallied up the AXP share count in the aggregate among *all* of the funds which held AXP at the 03/31/2026 reporting period (out of the 3,956 we looked at in total). We then compared that number to the sum total of AXP shares those same funds held back at the 12/31/2025 period, to see how the aggregate share count held by hedge funds has moved for AXP. We found that between these two periods, funds increased their holdings by 3,958,896 shares in the aggregate, from 57,432,618 up to 61,391,514 for a share count increase of approximately 6.89%. The overall top three funds holding AXP on 03/31/2026 were:
| » | Fund | Shares of AXP Held |
|---|---|---|
| 1. | Fisher Asset Management LLC | 9,250,373 |
| 2. | Nuveen LLC | 5,590,781 |
| 3. | UBS Group AG | 4,566,249 |

We'll keep following the latest 13F filings by hedge fund managers and bring you interesting stories derived from a look at the aggregate information across groups of managers between filing periods. While looking at individual 13F filings can sometimes be misleading due to the long-only nature of the information, the sum total across *groups* of funds from one reporting period to another can be a lot more revealing and relevant, providing interesting stock ideas that merit further research, like American Express Co. (Symbol: AXP).

Four leading AI models discuss this article
"The net increase in institutional ownership reflects a flight to quality rather than a fundamental growth catalyst, leaving AXP vulnerable to macroeconomic slowdowns."
The 6.89% aggregate increase in AXP holdings among institutional filers suggests a defensive rotation into high-quality financials. American Express benefits from a premium consumer base that remains resilient despite inflationary pressures, providing a wider net interest margin buffer than peers. However, the divergence between the 14 funds decreasing positions and the aggregate share increase indicates a 'smart money' split. Investors are likely betting on AXP’s superior credit quality, but the 13F data is a lagging indicator. With AXP trading near historical valuation multiples, the upside is capped unless we see a significant acceleration in card member spending volume or a pivot in the Fed's interest rate trajectory.
The aggregate increase in share count could simply reflect institutional rebalancing to match benchmark weightings rather than a conviction-based bullish thesis on AXP's underlying credit performance.
"Aggregate hedge fund AXP ownership rose 6.89% QoQ despite mixed batch signals, pointing to underlying institutional accumulation in a premium financial name."
Hedge funds boosted aggregate AXP holdings by 6.89% QoQ to 61.4M shares as of Q1 2026, with Fisher Asset, Nuveen, and UBS as top owners—suggesting institutional conviction in AmEx's affluent customer base and resilient fee revenue amid sticky consumer spending. While 14 of 19 recent filers trimmed (vs. 5 adding), the broader cohort's net buying outweighs that, potentially foreshadowing re-rating if Q2 earnings confirm travel/cross-border strength. Caveat: 13Fs lag 45 days and hide shorts, so pair with options flow for full picture.
This net buying could mask widespread short overlays or profit-taking after AXP's strong run, as 14/19 filers cut stakes amid macro risks like slowing consumer credit growth. Lagging data ignores recent Fed signals or delinquency upticks that could pressure margins.
"Aggregate 13F share increases are a weak buy signal when most funds reduced positions, the largest holders are index trackers, and short/derivative positions remain invisible."
The article's headline—'hedge funds buying AXP'—rests on a 6.89% aggregate share increase across 3,956 funds over Q1 2026. But this is mechanically weak evidence. First, the article itself admits 13F data omits short positions, hedges, and derivatives—so 'long shares up 4M' could mask a $2B bearish derivatives position. Second, 5 of 24 funds in the sample *increased* positions while 14 *decreased*—that's a 5:14 ratio suggesting net skepticism, not conviction. Third, Fisher, Nuveen, and UBS are passive/index-tracking shops; their AXP holdings likely track S&P 500 weighting, not active conviction. A 6.89% increase in a rising market is noise, not signal.
If AXP has underperformed the S&P 500 YTD, then a 6.89% increase in fund holdings would actually represent *outperformance* in accumulation—genuine conviction. The article doesn't provide AXP's YTD return or compare it to index weighting changes.
"13F ownership momentum is an unreliable near-term signal for AXP; real upside hinges on actual spend growth and credit quality, not fund-flow momentum."
News that 24 of 56 recent 13F filers hold AXP and aggregate holdings rose ~6.9% can signal institutional comfort with American Express as a high-quality, cash-generative financials franchise. But 13F data is lagging, long-only, and blind to shorts, options hedges, or reverse flows; the move may reflect mechanical factors like index rebalances or ETF flows rather than disciplined conviction. There’s no obvious near-term catalyst unique to AXP, and macro-driven consumer spend, travel demand, credit quality, and merchant mix will drive earnings more than fund-flow dynamics. Overall, this is a cautionary data point that supports a neutral stance rather than a clear buy.
The signal could be purely mechanical (index/ETF rebalancing) with little pricing power behind it; even if AXP benefits from a quality tilt, a consumer slowdown or rising credit losses could erase any modest multiple expansion.
"Institutional buying ignores the regulatory risk of AXP's premium merchant fee model, which is a greater threat than consumer credit cycles."
Claude is correct that 13F data is often mechanical, but both Claude and Gemini ignore the specific risk of the 'Amex-exclusive' merchant fee model. If the DOJ or FTC intensifies scrutiny on credit card network fees, AXP’s premium discount rate—its primary moat—faces a structural margin compression risk. Institutional buying might be a hedge against broader market volatility, but it ignores the regulatory headwinds that could decouple AXP from the broader S&P 500 financials performance.
"AXP's closed-loop model shields merchant fees from regulatory caps hitting open networks, supporting institutional conviction in resilient growth."
Gemini's DOJ/FTC risk ignores AXP's closed-loop moat: unlike Visa/MC's open networks, AmEx controls issuance and acceptance, sustaining premium discount rates (3.5-4% vs. peers' 2%) even under scrutiny. No major AXP-specific suits materialized post-Swain case. Overlooked: Q1 data showed 11% card spend growth from affluent travel, buffering any macro slowdown—explains 'smart money' net buying despite trims.
"AmEx's closed-loop model is defensible but not immune to regulatory re-pricing of discount rates, especially if affluent travel demand normalizes."
Grok's closed-loop moat argument is stronger than I credited, but it conflates two separate defenses. Yes, AmEx controls issuance—that's durable. But 'no major suits post-Swain' is weak comfort; the FTC's 2023 non-compete rule and ongoing scrutiny of fintech partnerships (Sofi, Square) suggest regulatory appetite is *rising*, not dormant. The 11% affluent travel spend is real, but it's also cyclical and priced in. Institutional buying could equally reflect flight-to-quality ahead of a consumer slowdown.
"Regulatory risk on merchant discount rates could compress AmEx margins, offsetting spend-driven upside from affluent travel and capping multiple expansion."
Particularly worth stressing is the regulatory risk around merchant discount rates. Grok focuses on AmEx's closed-loop moat; however, if the FTC/DOJ push toward open networks or cap fees, AmEx may be forced to absorb margin compression or raise member benefits, offsetting any upside from 11% affluent travel spend. The 6.9% holdings lift could be noise; what matters is resilience of margins, not just spend growth. This underappreciated risk could cap multiple expansion.
