What is P/NAV and why does it matter
Tanker stocks can feel mysterious. The companies own giant ships, the ships carry oil, and somehow that turns into a share price on your screen. P/NAV (Price-to-Net-Asset-Value) is the single most useful number you can use to figure out whether you are getting a deal. NAV stands for Net Asset Value, and for a tanker company it means roughly this: take what all the ships are worth on the open market today, subtract the company’s debt, and divide by shares outstanding. That gives you what one share is really backed by in steel.
Picture a used car dealership. The cars on the lot are worth $1 million on the open market. If someone offers to sell you the whole dealership for $800,000, you are getting $1 of car for 80 cents. That is a 0.80x deal. Pretty good. If the seller wants $1.3 million for the same lot, you are paying $1.30 for that same $1 of car. Not so good. Tanker stocks work exactly the same way, and the “cars” are the ships.
Tanker stocks usually trade somewhere between 0.70x and 1.30x NAV depending on where we are in the rate cycle. When freight rates are red hot and everyone is excited, the group can push above 1.10x. When rates collapse and the world hates shipping, you can find names below 0.85x. Below 0.85x is generally considered cheap. Above 1.10x is generally considered expensive. That is the framework. Now let’s see where the group sits today.
This week’s scorecard
| Ticker | Company | Price | P/NAV | vs. NAV | Signal |
|---|---|---|---|---|---|
| STNG | Scorpio Tankers | $81.68 | 0.80x | 20% discount | Cheap |
| ASC | Ardmore Shipping | $19.65 | 0.99x (P/B) | 1% discount | Fair |
| TNK | Teekay Tankers | $77.97 | 1.19x (P/B) | 19% premium | Pricey |
| HAFN | Hafnia | $8.87 | 1.26x (P/B) | 26% premium | Pricey |
| CMBT (EURN) | CMB.TECH (formerly Euronav) | $17.26 | 1.83x (P/B) | 83% premium | Pricey |
| INSW | International Seaways | $85.11 | 1.92x (P/B) | 92% premium | Pricey |
| DHT | DHT Holdings | $17.95 | 2.54x (P/B) | 154% premium | Pricey |
| FRO | Frontline | $39.00 | 3.28x (P/B) | 228% premium | Pricey |
Data sources: Evercore ISI (May 2026 STNG note), SEC 10-Q filings, Yahoo Finance, MacroTrends, GuruFocus, company Q4 2025 and Q1 2026 reports. P/B used as NAV proxy where direct P/NAV estimates were unavailable. Prices are most recent close as of mid-week ending May 22, 2026.
A note on data quality you should actually read. The P/B numbers for FRO, DHT, INSW, and CMBT look eye-popping because the book value (what the ships are recorded at on the balance sheet) is far lower than what those ships could fetch in today’s market. Tanker accounting depreciates ships every year, and several of these companies took huge write-downs after the 2014 to 2020 crash. Ship values have since soared. So when I show FRO at 3.28x book, that does not mean the stock is three times overpriced versus its fleet. It means book value is a poor stand-in for NAV in this cycle. A true P/NAV using current vessel appraisals would likely put FRO and DHT closer to 1.0x to 1.2x rather than 3x. For STNG I had a direct broker P/NAV figure from Evercore, which is why that one looks much lower than its book ratio. Treat the discount and premium percentages as a rough guide, not gospel.
What stands out this week
The most interesting name on the list is Scorpio Tankers. Evercore put out a note in May estimating STNG trades at a roughly 20 percent discount to year-end 2026 NAV. That makes STNG the clearest “cheap” call on the board this week. The stock has rallied hard from its 2025 lows in the $38 range, but the underlying fleet value has risen even faster as product tanker rates stayed strong through the spring. Worth keeping an eye on if you like the sector but want a margin of safety.
Ardmore Shipping looks attractive on raw book value, sitting essentially at parity (0.99x P/B). One source I found suggested ASC was around 0.66x of a broker NAV estimate, which would make it even cheaper than STNG. The product tanker names as a group are running ahead of the crude tanker names in apparent discount terms, which lines up with what brokers are saying about MR (medium range product tanker) fleet values lagging the stock moves.
On the other end, Frontline and DHT show the largest premiums to book value, but as I flagged above, do not read too much into that without adjusting for the conservative book values these crude tanker giants carry. The more honest read is that the whole group has rallied, the crude names led the charge, and you are now buying tanker exposure at the upper end of the historical valuation band. Nobody in this universe is screaming “fire sale” right now.
The bottom line
If you walked away with one thought, let it be this. The tanker group as a whole is trading rich after a big rally, with most names sitting near or above the upper end of the typical 0.70x to 1.30x P/NAV band. A couple of product tanker names (Scorpio and Ardmore) still offer real discounts to broker NAV estimates, while the big crude carriers look fully priced unless tanker rates push even higher. Beginners should remember that a “cheap” P/NAV does not mean a stock will go up. It just means you are paying less today for the steel and the cash flow that steel produces. Whether the steel earns good rates next year is a separate question, and it is the one that ultimately drives returns.
Quick glossary
P/NAV: Price-to-Net-Asset-Value, the ratio of a stock’s share price to what one share’s slice of the company’s assets (mostly ships, minus debt) is actually worth.
NAV: Net Asset Value, the market value of the fleet plus any cash, minus debt and other liabilities, divided by shares outstanding.
TCE: Time Charter Equivalent, the daily rate a ship earns after voyage costs like fuel and port fees are stripped out.
VLCC: Very Large Crude Carrier, the biggest oil tankers that haul about two million barrels per voyage.
MR: Medium Range, a smaller class of product tanker that carries refined fuels like gasoline and jet fuel.
