Is PSX undervalued?

PSX has a margin of safety of 53%: the stock closed at 259.63 on 5 Nov 2026 against a GLS average fair value of 548.05. 5 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.

There is a wide gap between DDM (73.72) and Graham Growth (1,668.15). 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.

Ranked against every other company we cover, PSX is clearly cheaper than it is fast-growing, so the nightly engine files it under Value (value score 62, growth score 14, out of 100).

Nine valuation models for PSX

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

Phillips 66 scores 9 of 9 on the Piotroski F-score, the nine yes/no tests of profitability, leverage and efficiency on the latest annual accounts - a strong reading that passes the "Piotroski 6 or more" Wheel Trade Filter with room to spare. A GLS Moat score of 4.1/10 is a weak reading: the accounts do not show returns and margins that competitors have been unable to wear down, so the Moat part of the Wheel Score contributes little.

Returns on capital are moderate - ROIC 8.5%, ROE 15.1%, ROA 6.0% - with debt at 0.79 times equity and a free-cash-flow yield of 14.2%.

The dividend yield is 1.93% at a payout ratio of 16%; 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. Revenue comes mainly from Consolidation, Eliminations 70%, Crude Oil 17%, Natural Gas Liquids 13% (quarter Q3 FY2026).

Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.

Wheel Score 61: Fair

A Wheel Score of 61 keeps Phillips 66 under 70, the mark only a stock that passes all 9 Wheel Trade Filters can reach: it fails filter 5, can repay its debt - 4.0 years to repay its debt (over 3). The parts: value strong, premium strong, moat fair, health strong, red flags strong, option trading strong, stability strong.

Implied volatility is 48% 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 44,323 contracts across all expiries - enough for the wheel at normal size.

Volume runs at 5.5M shares a day on a market cap of $101.3B, with a beta of 0.69 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that strong.

Upcoming events

The next earnings report is due on 3 Feb 2027, 90 days away - outside the window of a 30-45-day put sold today. The shares go ex-dividend on 17 Nov 2026 (1.33 per share), so a covered call sold before then carries a small early-assignment risk around that date.

No analyst upgrades or downgrades were recorded in the last 30 days.
