Porter’s 3X Screen Beats The Market

We Flagged This Stock Before Warren Buffett Did

This is Porter’s Daily Journal, a free e-letter from Porter & Co. that provides unfiltered insights on markets, the economy, and life to help readers become better investors. It includes weekday editions and two weekend editions… and is free to all subscribers.

Today – taking a break from our normal publishing schedule – we are continuing our “12 Days Of Christmas” series.

Better than seven swans a-swimming or 10 lords a-leaping, Porter & Co.’s version of the “12 Days Of Christmas” brings you something actually useful: hard-earned investment lessons to guide you through 2026. For the remainder of the year – in place of our regular research and insights – we will dish out key lessons from 2025… some earned from pain and others from gain. 

Over the past year, editors across all of our publications have recommended stocks, bonds, or other trades that have resulted in a mix of outsized performances and humbling underachievements. Having begun yesterday, December 23, and extending through January 2, we will reveal a pivotal lesson – about why a stock soared to double-digit returns, or why one languished. We will also explore the ones that got away – that we sold too soon or that we didn’t recommend at all. 

Analyst Jared Simons sets the parameters for our Saturday Stock Screen – part of the free research we share with subscribers to Porter’s Daily Journal. After setting the filter, Jared then helps Porter analyze the data that emerges and, occasionally, reports on what they think could be a future recommendation for Complete Investor or another Porter & Co. advisory. 

Below, Jared shares one such report that has become a big winner for the Complete Investor portfolio.

Every Saturday in Porter’s Daily Journal, we provide readers a behind-the-scenes look: publishing a quantitative stock screen to uncover the most compelling, highest-upside investment ideas. 

For Partner Pass members, we’ll occasionally spotlight one opportunity from the screen that appears especially attractive. These aren’t official recommendations, but early “on-the-radar” ideas that we feel we need to keep an eye on.

Today, we’re looking back at one of those screens and the Partner-only report that accompanied it… and share how this early look at a great company has become a big winner for our Partners and Complete Investors. 

These weekly screens apply our analysts’ proprietary filters to identify the strongest, most durable, capital efficient companies in the market. They are free for all readers – and week after week, they continue to surface businesses that outperform the market.

Our screens are inspired by some of the greatest investment minds of all time – from the Emerging Lindy Screen, which finds innovative growth companies with long-term staying power, to Marty Fridson’s Stock screen, built around the traits of history’s best-performing stocks. We also feature Porter’s 3X Screen, designed to uncover companies capable of tripling the market over time, as well as our Modified Munger Screen, based on the late Berkshire Hathaway vice chair’s simple approach to finding high-quality, long-term compounders.
