Issue #16 · Weekly Stock Analysis · July 22, 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.
Imagine a business that makes the humble cardboard box, the kind that shows up on every loading dock and retail shelf, quietly enabling the flow of goods from factory to front door. Packaging Corporation of America does exactly that with its containerboard and corrugated products, a straightforward operation that turns wood fiber into the everyday packaging that keeps commerce moving.
This outfit shows real strength in its ability to earn a respectable return on equity, lately 16.2 percent with a five-year average near 14.3 percent. That performance comes without heavy reliance on accounting tricks or extreme leverage, much like a castle whose walls stand firm because the ground beneath them is solid rather than because the drawbridge is pulled up tight. The company has generated steady revenue and net income growth over recent quarters, reaching $9.2 billion in trailing revenue and $0.7 billion in net income. Its moat, scored at 65.6 out of 100, rests on customer loyalty and brand recognition in a market where reliable supply and quality matter more than flash. High institutional ownership at over 100 percent of shares suggests outside investors see capable hands at the helm, and the managers appear focused on running the packaging boat rather than trying to row against poor economic currents.
Yet no business is without its shortcomings, and it pays to acknowledge them plainly. The debt-to-equity ratio sits at 0.95 times, which introduces some sensitivity to rising interest rates or economic dips that could squeeze margins. As a player in the consumer cyclical sector, earnings can swing with broader spending patterns, and the current price-to-earnings ratio of 25.5 times does not scream bargain. Past growth rates in net worth, even when impressive, cannot be counted on to repeat at the same pace amid market fluctuations and competitive pressures in paper and packaging.
Over the long haul, Packaging Corporation of America could still reward patient owners if it continues delivering consistent returns on capital while management allocates resources wisely. Buying at sensible prices and holding through cycles has always been the surer path than chasing quick gains. For those looking to act on this, the ticker for Packaging Corporation of America on eToro is $PKG.

Picture a neighborhood where one shoemaker's boots have been the go-to choice for generations because folks trust them to hold up through rain, mud, and long walks without fancy new gimmicks each season. That steady pull is what stands out with NIKE, a company whose brands keep drawing customers back across continents.
This outfit has a wide moat, much like a castle protected from invaders, built on brand recognition and customer loyalty that scores 87 out of 100. Its latest return on equity hits 20.9 percent, with a five-year average of 17.5 percent, showing solid earnings on capital employed without heavy reliance on accounting tricks or excessive borrowing—the debt-to-equity ratio sits at a manageable 0.74 times. Revenue has held steady near 11 billion dollars per quarter lately while net income has climbed from 0.2 billion to 1.1 billion, pointing to resilient operations in a consumer cyclical field. Management appears focused on the core business rather than chasing every trend, and the 15.9 times price-to-earnings ratio plus 11.5 times EV-to-EBITDA suggest the market is not demanding sky-high growth to justify the current 62.6 billion dollar market cap.
Still, no business sails without some rough waters. Being tied to fashion and discretionary spending means economic slowdowns or shifts in tastes could squeeze margins, and competition from nimbler rivals might test that moat over time. The stock's price-to-book ratio of 3.3 times reflects some premium for the brands, yet past growth rates like those seen in stronger years may prove harder to repeat amid market swings.
In my view, the long-term case rests on patience with a proven brand that generates consistent owner earnings. At these valuations, an investor willing to hold through cycles could find sensible value if the company keeps delivering on its fundamentals rather than chasing short-term earnings spikes.
