TIM S.A. (TIMB): fair value, margin of safety and Wheel Score
Ticker symbol TIMB · Communication Services · Telecommunications Services · Brazil · ADR · Blend Quality
TIMB is an American depositary share (ADR): the US listing of TIM S.A., whose own shares trade on its home exchange. It trades in dollars during US hours; currency moves and the home country's rules also affect it, and the depositary bank charges a small yearly fee.
Is TIMB undervalued?
TIMB has a margin of safety of 68%: the stock closed at 18.20 on 5 Nov 2026 against a GLS average fair value of 56.87. 8 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 9.81 while Payback Time gives 119.20. 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, neither cheapness nor growth clearly wins for TIMB, so the nightly engine files it under Blend (value score 66, growth score 51, out of 100). It also carries the Quality tag (Quality = moat 7.5+ out of 10 and Piotroski 7+).
Nine valuation models for TIMB
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. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.
| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | 72.99 | +301% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 18.53 | +2% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 87.28 | +380% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 37.56 | +106% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 63.18 | +247% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 84.73 | +366% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 119.20 | +555% | Eight years of compounded free cash flow: the price at which the business pays for itself |
| DDM | 9.81 | -46% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 18.50 | +2% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | -7.46 | -141% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 24.48 | +35% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
On financial health TIMB scores 8/9 (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 7.6 out of 10 - high returns on capital, steady margins and growth that held up through bad years point to a durable business.
Returns on capital are moderate - ROIC 8.2%, ROE 18.0%, ROA 7.6% - with debt at 1.19 times equity and a free-cash-flow yield of 19.2%.
The dividend yield is 3.66% at a payout ratio of 124%; for a wheel trader holding assigned shares the dividend adds to the covered-call premium, and the ex-dividend date is worth knowing before a call is sold.
Institutional ownership scores 1/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 8 / 9 | ROIC | 8.2% |
|---|---|---|---|
| GLS Moat | 7.6 / 10 | ROE | 18.0% |
| Debt / equity | 1.19 | ROA | 7.6% |
| Free-cash-flow yield | 19.2% | Payout ratio | 124% |
| Institutions | 1 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 55: Fair
TIMB scores 55 out of 100 on the Wheel Score (Fair band, 50-69) because it fails filter 1, options that actually trade - options too quiet (140 open interest, 49 a day). A stock must pass all 9 Wheel Trade Filters to reach 70. Otherwise the parts read: value strong, premium strong, moat good, health strong, red flags strong, option trading weak, stability good.
Implied volatility is 45% 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. Chain open interest is thin - 140 contracts across every expiry - so fills at a fair price are not guaranteed; a 30-45-day put may not exist at a usable strike.
Volume runs at 1.0M shares a day on a market cap of $8.7B, with a beta of 0.11 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that good.
| Filter | Wheel Trade Filter | Result | Detail |
|---|---|---|---|
| 1 | Options that actually trade | Fails | options too quiet (140 open interest, 49 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 | 68% below fair value | |
| Premium | Strong | implied volatility 45% | |
| Moat | Good | moat 7.6/10 | |
| Health | Strong | Piotroski 8/9 | |
| Red Flags | Strong | Red Flags score 90/100 | |
| Option trading | Weak | 49 contracts a day, 140 open interest | |
| Stability | Good | beta 0.11, $8.7B company |
