"Price is what you pay. Value is what you get."
Issue #28 · Weekly Stock Analysis · October 14, 2026
Welcome to this week's edition of The Buffett Lens, where we apply Warren Buffett's time-tested investment principles to identify stocks with durable competitive advantages, strong management, and sensible valuations.
Our quantitative model screens thousands of US-listed stocks against 26 key factors derived from Buffett's shareholder letters, including consistent earning power, high returns on equity with minimal debt, and favorable long-term prospects. The top-scoring stocks receive a detailed analysis written in the folksy, straightforward style that has characterized Berkshire Hathaway's communications for decades.
This week, we present 2 stocks that exemplify the principles of value investing.
Picture an old-fashioned oil derrick sitting on a patch of land that keeps producing year after year, as long as the owner tends to the equipment and doesn't borrow too much to drill extra holes. Devon Energy strikes me as that kind of operation, digging in basins across the country for oil and gas without flashy promises.
This outfit shows real strengths that line up with sound principles. Its asset base and cost advantages earn a moat score of 87 out of 100, much like a castle protected from invaders by natural barriers. The debt-to-equity ratio sits at just 0.28 times, keeping leverage low and avoiding gimmicks that inflate returns. Over five years the average return on equity reached 13 percent, and lately it stands at 7.9 percent on a market capitalization of 54.9 billion dollars. Recent quarters show revenue climbing toward 19.7 billion dollars annualized with net income at 3.3 billion, reflecting managers who know how to operate in the energy patch. Valuation looks reasonable too, with a price-to-earnings ratio of 15 times and enterprise value to EBITDA at 6.8 times, suggesting the price hasn't run far ahead of the underlying economics.
Of course, every business has its limits, and humility calls for noting them plainly. Energy prices swing with supply gluts or sudden demand drops, which can squeeze even capable operators. The latest return on equity trails the five-year average, and insider ownership at 0.8 percent is modest, though institutions hold nearly 95 percent. Past growth rates in this field rarely repeat, and book value alone doesn't capture the true worth when commodity cycles turn.
Looking ahead, Devon's focus on proven basins and restrained borrowing positions it for steady compounding if management continues to allocate capital wisely. At the current price near 49.92 dollars, the shares appear to offer a margin for long-term owners who can wait through the ups and downs of the energy cycle rather than chase quick moves. For those looking to act on this, the ticker for Devon Energy Corporation on eToro is $DVN.

Think of a well-maintained house that keeps its value through decades of weather and wear. The paint and coatings on it do not just look nice; they shield the structure from damage year after year. PPG Industries does much the same on a global scale, supplying the protective layers that buildings, cars, and factories rely on to last longer.
This outfit shows real strength in delivering high returns on the capital it employs, much like the businesses I favor that earn solid rates without leaning on tricks or heavy borrowing. Its average return on equity over five years sits near 20 percent, and the latest figure holds at 18.6 percent. Revenues have moved steadily from around 4.2 billion to 4.5 billion across recent quarters, with last twelve months reaching 16.4 billion and net income at 1.6 billion. That kind of consistency points to a business with durable economics rather than fleeting trends. The moat score of 72 out of 100, built on cost advantages and resource access, suggests it can hold its ground against rivals. At a price-to-earnings ratio of 15.5 times and enterprise value to EBITDA around 10.7 times, the shares trade at a level that leaves room for long-term owners to benefit if the company keeps compounding value.
Still, no investment comes without its share of uncertainties. Debt to equity stands at 0.88 times, which is not extreme but does require watching if interest rates stay elevated. Net income has eased a bit in the most recent quarters compared with earlier ones, and insider ownership remains low at just 0.1 percent. Market swings can also affect reported results even when the underlying operations stay sound, as we have seen in past periods when growth rates naturally slow from earlier peaks.
Over time, the steady demand for coatings in construction, autos, and industry should support patient owners who focus on intrinsic value rather than short-term moves. The current price appears sensible for those willing to hold through cycles, letting the business's earning power work in their favor without expecting overnight miracles.
