"Price is what you pay. Value is what you get."
Issue #30 · Weekly Stock Analysis · October 28, 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.
Investing in an oil and gas outfit like Ovintiv reminds me of owning a sturdy well in the backyard that taps into underground reserves. You do not control the rain or the market price per barrel any more than a farmer controls the weather, but if the well sits on solid ground and costs little to maintain, it can deliver steady value over decades rather than chasing flashy short-term gushers.
This company shows real strengths that line up with sound principles. Its asset base and cost advantages create a moat score of nearly 80 out of 100, much like a castle protected from invaders by natural barriers that competitors struggle to cross. The latest return on equity sits at 8 percent, close to its five-year average, and debt stays moderate at 0.44 times equity. That avoids the undue leverage that can erode owner returns, especially when inflation pressures mount. Recent quarters show revenue climbing toward 3 billion dollars and net income reaching half a billion, with last-twelve-month figures at 9.8 billion in revenue and 0.9 billion in profit. Institutional owners hold nearly all the shares, suggesting capable hands are running the operations in the Permian, Anadarko, and Montney regions without relying on accounting tricks. At a price-to-book of 1.5 times and enterprise value to EBITDA around 7.6 times, the valuation leaves room for the business's intrinsic worth to shine through over time rather than depending on book numbers alone.
Of course, no investment comes without shortcomings, and I would be remiss not to note them plainly. Energy prices swing with global forces far beyond any manager's control, which can turn even a decent return on equity into a modest real gain for owners when costs rise. The 8 percent ROE is respectable but falls short of the high-20s levels that truly compound wealth through thick and thin. Insider ownership at just half a percent means alignment is present but not overwhelming, and commodity businesses rarely offer the predictable economics of a branded consumer staple.
Still, for the patient investor focused on long-term value, Ovintiv's combination of asset strength, controlled leverage, and improving earnings power suggests it could compound sensibly at today's price of around 71 dollars, provided one buys with an eye on intrinsic worth rather than quarterly noise. The ticker for Ovintiv Inc. on eToro is $OVV.

Imagine a bustling medical conference hall where doctors from every corner gather not just once a year but every day to swap notes, read the latest studies, and connect with peers. That is the essence of Doximity's platform, a digital meeting place that keeps professionals returning because the conversation never stops and the content stays relevant.
This outfit has built a respectable earnings record, posting an 18 percent return on equity lately and averaging near 17 percent over five years, all while carrying almost no debt. That combination fits the test of strong managerial performance: generating solid returns on the capital employed without fancy leverage or accounting tricks. The low debt ratio of just 0.01 times equity means the business is not borrowing its way to growth, which leaves room for steady compounding. Its moat score near 73 reflects patent protection and research capabilities that help keep rivals at bay, much like a well-positioned store that draws repeat customers through convenience and specialized offerings. Revenue has climbed steadily from negligible levels to 700 million dollars over the last four quarters, with net income reaching 200 million, showing the kind of consistent earning power that rewards patient owners.
Still, no business is without its uncertainties. Healthcare rules can change quickly, and any shift in how pharmaceutical companies sponsor content or how doctors access information could trim margins. The company is still young in public markets, so its growth may not repeat at the same pace forever, and market swings could affect reported results even if the underlying platform remains sound. Insider ownership sits at a modest 3 percent, which is enough to align interests but leaves room for wondering whether management will stay fully invested alongside outside shareholders.
Over the long haul, a platform that serves an essential professional network can keep delivering value if the operators continue focusing on useful features rather than chasing every trend. At a price-to-earnings ratio of about 16 times and a price-to-book near 3 times, the current valuation of 6.1 billion dollars does not appear stretched for a business with these returns and minimal leverage. A sensible investor would watch for steady execution, add shares gradually when prices dip, and hold through the inevitable ups and downs, letting time and compounding do the heavy lifting. For those looking to act on this, the ticker for Doximity, Inc. on eToro is $DOCS.
