Interactive Brokers Group, Inc. (IBKR): fair value, margin of safety and Wheel Score
Ticker symbol IBKR · Financial Services · Investment - Banking & Investment Services · United States · Class A common stock · Growth
IBKR is Interactive Brokers Group, Inc.'s Class A common stock. The classes own the same business, share the same earnings report and trade within a few cents of each other; what differs is mainly the vote each share carries - the company's annual report sets out the voting rights.
Is IBKR undervalued?
IBKR has a margin of safety of 40%: the stock closed at 77.88 on 5 Nov 2026 against a GLS average fair value of 129.70. 4 of the 9 valuation models that produced a number sit above the price. Our scans treat a discount this large as a strong starting point for a cash-secured put, not as a verdict - the fair value is a model output, and a wide gap can mean the models are missing something the market knows.
The 9 models disagree widely: DDM gives 4.93 while 10 Cap gives 508.64. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.
Ranked against every other company we cover, IBKR is clearly faster-growing than it is cheap, so the nightly engine files it under Growth (value score 32, growth score 72, out of 100).
Nine valuation models for IBKR
Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number.

| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | 14.64 | -81% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 28.37 | -64% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 116.39 | +49% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 48.46 | -38% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 159.32 | +105% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 508.64 | +553% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 257.63 | +231% | Eight years of compounded free cash flow: the price at which the business pays for itself |
| DDM | 4.93 | -94% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 28.92 | -63% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | -2.66 | -103% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 105.00 | +35% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
On financial health IBKR scores 7/9 (Piotroski): most of the nine tests - positive earnings and cash flow, falling debt, rising margins and turnover - are passed, which is the kind of balance sheet a wheel trader is happy to be assigned. The GLS Moat score is 5.3 out of 10: a record that is solid on some of the four parts the score weighs (returns on capital, pricing power, lasting growth, balance sheet) and weaker on others.
Returns on capital are high - ROIC 18.3%, ROE 18.3%, ROA 0.5% - with debt at 0.00 times equity and a free-cash-flow yield of 8.3%.
The dividend yield is 0.43% with a payout ratio of 9% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Commissions 90%, Risk Exposure Fees 3%, Market Data Fees 3% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales; the last recorded insider buy was on 2 Nov 2026.
| Piotroski F-score | 7 / 9 | ROIC | 18.3% |
|---|---|---|---|
| GLS Moat | 5.3 / 10 | ROE | 18.3% |
| Debt / equity | 0.00 | ROA | 0.5% |
| Free-cash-flow yield | 8.3% | Payout ratio | 9% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 90: Prime
IBKR scores 90 out of 100 on the Wheel Score, in the Prime band (85 and above): it passes all 9 Wheel Trade Filters and ranks strongly on value strong, premium strong, moat fair, health good, red flags strong, option trading strong, stability strong. Prime stocks stand out among those that pass - the Sunday Scan is the top 10 by Wheel Score.
Implied volatility is 42% on the near-the-money contracts 20-60 days out - inside the 35-60% sweet spot the Wheel Score rewards most: enough premium to be worth selling, not so much that the risk is unpaid. The option chain is deep: 92,036 contracts of open interest across all expiries, which means tight fills at most strikes.
Volume runs at 7.5M shares a day on a market cap of $136.9B, with a beta of 1.38 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score rates that strong.
| Filter | Wheel Trade Filter | Result | Detail |
|---|---|---|---|
| 1 | Options that actually trade | Passes | Listed options with 1,000+ contracts of open interest and 100+ traded a day |
| 2 | A real business, not a gamble | Passes | Profitable over the last twelve months - not a speculative stock, fund or note |
| 3 | Below fair value | Passes | Trading below the nine-model average fair value (margin of safety above 0) |
| 4 | Financially healthy | Passes | Piotroski F-score 6 or more out of 9 (a company with no score on file passes) |
| 5 | Can repay its debt | Passes | Long-term debt repaid from 3 years of operating cash flow or less (6 for real estate and utilities; banks and insurers are not judged on it) |
| 6 | No serious red flags | Passes | Red Flags score 60 or more out of 100 (earnings, margins, debt, analysts, filings and price checked the same way for every stock) |
| 7 | A premium worth selling | Passes | Implied volatility 25-80% (enough premium, not a lottery ticket) |
| 8 | Big enough | Passes | Market cap $1 billion or more |
| 9 | Not a penny stock | Passes | Share price $5 or more |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Strong | 40% below fair value | |
| Premium | Strong | implied volatility 42% | |
| Moat | Fair | moat 5.3/10 | |
| Health | Good | Piotroski 7/9 | |
| Red Flags | Strong | Red Flags score 100/100 | |
| Option trading | Strong | 6,485 contracts a day, 92,036 open interest | |
| Stability | Strong | beta 1.38, $136.9B company |
