Zelikovic Investments Yoav Zelikovic | “Interactive Brokers (IBKR). In his book, One Up on Wall Street, the renowned American investor Peter Lynch describes how the best investment ideas are in companies known well to the investor through everyday use of their products. IBKR is just that for me. The company was founded in 1978 by Thomas Petterfly, a Hungarian with no formal education who arrived in the U.S. as a penniless immigrant. He established a company that is now among the world's largest and leading brokering companies and he himself is among the richest people in the world. I have been using IBKR's excellent platform for over a decade but (I own my sin) I hesitated to buying its shares (and while I dawdled its stock CAGR'd at annual rate of 25%) although I was personally familiar with the quality of its services and I worked closely with its representatives in Israel. I am happy that I have finally revisited the matter and that I included its stock in our portfolios. IBKR is currently among the largest and most efficient brokerage companies in the U.S., reporting profitability rates higher than those of Visa and Mastercard. The platform is mostly automatic. IBKR IPO'ed with a market cap of ~$12B in 2007 and it is now valued at over $100B. The company has over 4 million clients worldwide, including Europe and Asia, with $700B of capital held in IBKR accounts, all maintained by only 3000 employees working for the company, mostly engineers. IBKR offers a preferred investment platform to many hedge funds worldwide with access to over 170 global stock exchanges. Thanks to its unique platform, IBKR is able to offer its clients much better execution of trades in comparison to most other brokers and very low costs. For example, when investors seek to purchase stock or convert currency then, unlike other brokers, IBKR will offer them the actual exchange rate without mark ups. Despite these low costs to customers- IBKR is a very profitable company. The Majority of IBKR's profits are derived from Net Interest Income, the difference between the interest charged by IBKR, mainly on margin loans (loans for purchasing securities) and the company's cost of lending the funds. In 2025, company stock value rose to over 45% and has continued raising YTD (over 40%) and, concurrently, its average profit growth rate is still nearly 25%. This company's stock is not especially cheap and trades at an elevated P/E, but in light of its unique performance and almost monopolistic status as a known international broker, we continue to own the shares. In 2025 alone, the number of new accounts in IBKR increased by over 30%. It is worthy to note that, in general, the more volatility in the markets, clients tend to be more active in their brokerage accounts, rendering IBKR especially attractive in bearish markets too. I am confident that this company will continue to grow and increase its profits in the future.” | NEUTRAL | Q2 2026 Aug 3, 2026 | View Pitch |
Tectonic Investors Portfolio Manager | “Interactive Brokers was one of the Fund's standout listed performers over the quarter, with the share price appreciating by approximately +30%. The company's Q1 2026 result, reported in April, showed record net revenues and a pre-tax profit margin of 77%, underscoring the operating leverage inherent in IBKR's low-cost, highly automated brokerage model. The business continued to benefit from strong trading activity across its platform, with June daily average revenue trades (DARTs) reported +53% higher than the prior year, reflecting continued growth in both retail and institutional client engagement globally. Beyond the strong underlying trading metrics, the quarter was notable for a series of product announcements that reinforced IBKR's position as one of the leaders of the brokerage industry. The company launched a unified interface for trading prediction markets across Kalshi, CME Group and its own ForecastEx platform, expanded its agentic trading capabilities through integrations with leading AI platforms, and added access to Korean equities via Nextrade. These developments have reinforced our long-held view that IBKR remains one of the best-positioned businesses to benefit from the structural growth in global trading volumes and the ongoing shift of assets toward low-cost, technology-driven platforms. The company's performance in recent quarters has resulted in continued analyst upgrades, including an addition to Goldman Sachs's US Conviction List during the quarter.” | NEUTRAL | Q2 2026 Jul 11, 2026 | View Pitch |
Hinde Group Marc Werres | “This quarter's portfolio update covers our position in Interactive Brokers Group, Inc. class A common stock (NASDAQ: IBKR). IBKR was the most significant positive contributor to the portfolio's return in 2025. IBKR is a compounder investment that Hinde Group has held since inception, with some adding and trimming along the way. Our position in IBKR has delivered a 26.8% compound annual return over our more than decade-long holding period. Interactive Brokers is a highly automated global securities firm that specializes in routing orders and processing trades in securities, futures, foreign exchange instruments, bonds and mutual funds on more than 170 electronic exchanges and market centers around the world. Interactive Brokers custodies and services accounts for hedge and mutual funds, registered investment advisors, proprietary trading groups, introducing brokers and individual investors. More than two-thirds of IB's customers are based in Europe and Asia and an even greater share of its new customers come from those regions. Interactive Brokers delivered another year of stellar operating results in 2025. Total customer accounts and customer equity grew 32% and 37%, respectively. Commission revenue grew 26%. The daily average for the CBOE Volatility Index (VIX) came in at 18.97 for 2025, just below the historical daily average of 19.43 and up from 15.58 for 2024. Higher market volatility typically drives increased trading activity among IB's customers. Net interest income grew 13.2% in 2025 despite multiple cuts to the federal funds rate since September 2024. Growth in average customer credit balances and customer margins loans of 28.0% and 30.8%, respectively, more than offset a 27 basis point decline in IB's net interest margin to 2.08%. Adjusted EPS grew 24.4%, an outstanding result considering the headwind Interactive Brokers faced from monetary policy easing by the Fed. Notwithstanding IBKR's tremendous performance over the past two years, IBKR still offers an attractive prospective return. While there is less scope for capitalization rate improvement going forward, Interactive Brokers should still grow its earnings at least at a mid-teens annual rate. Interactive Brokers also aims to pay out a dividend equivalent to a 0.5% to 1.0% yield. Between earnings growth and its dividend yield, IBKR seems poised to deliver a high teens or better annualized return over the coming years. IBKR would need to trade at more than $100 per share today to offer a market-level return. BSD Analysis: Interactive Brokers continues to benefit from its industry-leading automated platform, maintaining a positive 2026 outlook as equity markets remain supported by quiescent inflation and central bank easing. The firm is capitalizing on the high-interest-rate environment to drive interest income while concurrently growing its global customer base through ultra-low margin and commission rates. Analysts note that the company is well-positioned to navigate the "valuation risk" prevalent in today's tech-heavy indices by offering investors broad access to international markets and high-yield cash accounts. With a low risk of recession projected for the first half of 2026 and sustained momentum in company earnings, Interactive Brokers remains a preferred choice for active traders and institutions. Its fortress balance sheet and lack of significant government debt exposure provide a safe harbor for investors looking to diversify away from traditional banking risks.” | BULL | Q4 2025 Feb 13, 2026 | View Pitch |

Comus Investment Aaron J. Saunders | “We had a good year in 2025, however we were severely hamstrung by InteractiveBrokers' move to limit Americans from buying small Hong Kong equities. As a result, international clients of mine, who comprise the vast bulk (94%) of my AUM, experienced a return of 83.11%, as I continued buying small companies in the world's cheapest developed market throughout late 2024 and 2025. The returns chart you see above will be permanently marred by IBKR's asinine stunt, as the Comus account is US-based and they cost our Americans a good chunk of change. For whatever reason, as I mentioned in the 2024 letter, they deemed Americans unable to separate legitimate company from scam stock in that market while allowing foreigners to continue buying whatever they liked. It appeared they had received many complaints through the 2021-24 period of HK stock losses and as a result, restricted investors from profiting from the likely and predictable gains to those wise enough to buy when fear was at its peak. Now that global investors deem both HK and China investible again, returns in many stocks there have been explosive and we had our best year to date. IBKR made another change this year, and one that makes some sense. They limited the annual % of AUM fee that advisors can charge to 2%, so as you can see in the table above, it provides a small but meaningful benefit to clients as they go from 2.52% to 2% annual advisory fees. BSD Analysis: Interactive Brokers runs a brokerage like a software company. Low costs and automation attract active traders globally. Higher rates boost net interest income. Volatility increases engagement. The platform scales with minimal incremental cost. Investors underestimate operating leverage. Competition struggles to match pricing. This is financial infrastructure for traders. Efficiency wins.” | BULL | Q4 2025 Jan 22, 2026 | View Pitch |
TimesSquare Capital Management U.S. FOCUS Growth Equity strategy Portfolio Manager | “Interactive Brokers Group Inc. offers custody and account services for hedge funds, mutual funds, exchange-traded funds, registered investment advisers, and individual investors. Third-quarter earnings surpassed Street estimates. The upside was driven by robust account growth, higher revenues, and lower expenses. December marked the thirteenth consecutive month with year-over-year account growth above 30%. Reflecting a broader market pullback, total client Daily Average Revenue Trades (DARTs) declined sequentially in December as volumes softened across equities, options, and futures. Despite this year-end dip, fourth-quarter DARTs comfortably surpassed Wall Street estimates. Shares of Interactive Brokers fell by -6% in the quarter. BSD Analysis: Interactive Brokers runs a brokerage like a software platform, optimized for automation and scale rather than marketing spend. Its low-cost, high-functionality offering attracts active traders and institutions others can't profitably serve. Higher rates lifted net interest income, but volatility is the real earnings accelerator. Incremental accounts cost very little to support, creating extreme operating leverage. Investors fixate on cyclical trading volumes. Meanwhile, global market access and product breadth quietly drive share gains. Pricing discipline protects margins competitors can't match. This is financial infrastructure for serious users, not gamified speculation.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
The Bristol Gate U.S. Equity Strategy Achilleas Taxildaris | “Late in the quarter we bought Interactive Brokers (IBKR). Interactive Brokers is a leading automated global electronic broker that provides sophisticated investors with low-cost direct access to trade various asset classes across over 160 markets worldwide. The company represents a high-quality franchise defined by a fortress like balance sheet, a sticky client base with high switching costs, and an automated infrastructure that generates superior margins. We believe this low-cost advantage will continue to support market share gains, generate attractive account growth and produce sustainable mid-teens dividend growth. BSD Analysis: Interactive Brokers runs a brokerage like a software company, optimized for efficiency rather than marketing flash. Its low-cost, high-functionality platform attracts active traders, institutions, and global clients others can't profitably serve. Higher interest rates boosted net interest income, but trading volatility is the real accelerator. Operating leverage is extreme because incremental accounts cost very little to serve. Investors focus on cyclical trading volumes and miss structural share gains. Automation and scale protect margins even during slow markets. Competition struggles to match pricing without destroying economics. This is financial infrastructure for serious users, not gamification. When markets move, IBKR prints.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
LMN Capital Laurenz Nienaber | “Interactive Brokers is a classic compounder that benefits from higher interest rates and market volatility. The company reported strong account growth, up 26% year-over-year, and client equity reached new highs. IBKR's low-cost structure and best-in-class technology platform attract sophisticated investors and active traders. The net interest income remains a significant tailwind, although we are mindful of potential rate cuts. However, even in a lower rate environment, the core brokerage business is compounding at a double-digit rate. We believe the market underappreciates the stickiness of its client base and the operating leverage inherent in its model. BSD Analysis: Interactive Brokers is an unassailable, high-margin global brokerage oligopolist whose premium valuation (30.87x Forward P/E) is justified by its superior technology and efficiency. The core moat is its highly automated, low-cost platform, which attracts both institutional traders and active retail investors globally. This technology translates directly to superior profitability, evidenced by the 2.15% recent rise in EPS estimates. The company is strategically focused on expanding its market share among sophisticated traders, where its deep liquidity and low commissions provide an unmatched competitive advantage. With projected FY 2025 EPS growth of 17.05% and a high Zacks Rank, IBKR is a conviction bet on the structural dominance of technology-driven financial execution.” | BULL | Q2 2025 Jun 30, 2025 | View Pitch |
“Interactive Brokers is a high-quality global brokerage boasting robust account growth and excellent operating margins. However, because its revenue depends heavily on net interest income, the threat of a potential recession and rate cuts under new tariff policies changed the investment outlook, prompting the manager to exit.” | BEAR | Q1 2025 Mar 1, 2025 | View Pitch | |
LVS Advisory Defensive Portfolio Manager | “LVS increased its holding in Interactive Brokers to its maximum 10% cost limit, citing an attractive goldilocks environment of high interest rates and rising stock prices. The manager believes market skepticism over net interest income sustainability is misplaced given economic strength and strong KPIs.” | BULL | Q2 2023 Jul 18, 2023 | View Pitch |
LVS Advisory Defensive Portfolio Manager | “Interactive Brokers is the fund's largest holding and benefits from a superior model that shares higher interest rate upside with customers via competitive rates on cash. Because of its low-risk balance sheet, the company is well-positioned to capture market share from competitors focused on liquidity preservation.” | BULL | Q1 2023 Apr 13, 2023 | View Pitch |
