KT Corporation (KT): fair value, margin of safety and Wheel Score

Is KT undervalued?

At 18.57 (close of 16 Oct 2026), KT trades 100% below the GLS average fair value of 21,490.56. That average comes from 9 models run on the latest filings, and 8 of them land above the current price. Margins of safety over 30% are the exception rather than the rule across the ~7,400 stocks we value each night, so the number earns KT Corporation the full Value points in the Wheel Score - and a closer look at what the market is pricing in.

There is a wide gap between GLS Growth (16.15) and 10 Cap (90,893.97). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.

The nightly engine files KT under High Yield Income: a dividend yield above 4%.

Nine valuation models for KT

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.

Quality and financial health

KT Corporation scores 5 of 9 on the Piotroski F-score: a middling result that falls one point short of the Sunday Scan's "6 or more" rule. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. A GLS Moat score of 4.8/10 is a weak reading: the ten-year history the score grades (revenue, EPS, book value, margins, cash flow, share count, ROIC) has not been steady, so the Moat part of the Wheel Score contributes little.

Returns on capital are moderate - ROIC 5.8%, ROE 9.7%, ROA 4.0% - with debt at 0.69 times equity and a free-cash-flow yield of 13.8%.

The dividend yield is high at 4.76% (payout ratio 47%). A yield this size is often the market's way of pricing a risk to the payout, so the health score and cash flow matter more than usual.

Institutional ownership scores 3/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.

Wheel Score 83: Prime

With a Wheel Score of 83, KT Corporation sits in the Prime band - price, quality and premium all line up for the wheel strategy. The parts: Value 25/25, Health 11/20, Moat 7/15, Premium 20/20, Stability 20/20. A high score is a ranking, not a signal: it says nothing about timing, the earnings date or your position size.

Implied volatility is 40% on the near-the-money contracts 20-60 days out - inside the 35-60% range the Wheel Score pays full marks for: enough premium to be worth selling, not so much that the risk is unpaid. Chain open interest is thin - 79 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 2.5M shares a day on a market cap of $9.0B, with a beta of 0.05 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 20 of 20.

The Wheel Score ranks ~7,400 US stocks for selling cash-secured puts and covered calls; it is updated nightly and is not a recommendation. The walkthrough lesson shows how the score fits into a trade, start to finish.

Upcoming events

The next earnings report is due on 6 Nov 2026 (before the open), 21 days away; a 30-45-day put sold today would expire after it, which is worth weighing against the premium.
