AI Summary
Summary
The author describes an experiment where an AI (Claude) constructs a 20-stock value portfolio using screening rules and fundamental analysis, claiming outperformance since late April 2026.
The thesis is that AI can generate superior long-only value picks by systematically filtering non-cyclical sectors and applying strict financial ratio thresholds.
Quality assessment: This is a moderately researched backtest/forward test with transparent methodology but lacks deep fundamental analysis on individual holdings; it's more of an intriguing data point than rigorous due diligence.

Claude became the de-facto way I did a lot of equity research, since it can do so many things, even with just public data from the web. I decided to run an experiment (still in progress) by giving it tons of curated data to see if it could build a value portfolio that could beat the market. I launched it at the end of April and here's the verdict so far, as of 07/17/2026:
|Performance YTD|Performance since Inception|S&P YTD|S&P since Inception|
|:-|:-|:-|:-|
|16.84%|12.88%|9.8%|5.2%|
And here are the holdings, in case anyone is interested:
|Symbol|YTD Performance|Weight|
|:-|:-|:-|
||
|NJR|\+28.9%|16.76%|
|TRV|18.5%|11.76%|
|GL|33.3%|9.14%|
|CASH|29.2%|8.04%|
|ADUS|6.8%|6.79%|
|FG|7.8%|6.56%|
|APAM|\-5.4%|5.63%|
|HCI|\-3%|4.58%|
|UFCS|40.5%|4.39%|
|KHC|7.5%|4.01%|
|CAG|\-16.4%|3.34%|
|SLDE|11%|3.12%|
|ADT|\-11.9%|2.54%|
|NRDS|\-26.7%|2.51%|
|ASO|\-6.8%|2.43%|
|SKWD|20.3%|2.23%|
|SBH|4.6%|2.22%|
|OSCR|92.8%|1.66%|
|UPBD|31.2%|1.15%|
|PRG|61.8%|1.12%|
And I'll share the methodology behind it as well:
Screening rules to define the universe:
* No cyclical industries: Oil &Gas, Airlines, Auto, Homebuilding, Semiconductors
* Key criteria for ratios:
* P/E: 1-35
* P/S: 0.1-10
* P/B: 0.3-10
* Price to Free Cash Flow: 1-35
* Operating Profit Margin: 0.05-1
* Gross Profit Margin: 0.20-1
* Current Ratio: 0.8-20.0
* Debt to Equity: 0.0-2.5
* Operating Cash Flow to Sales: 0.05-1.0
After defining the universe, the AI analyzes every financial filing and transcript call to firmly understand how these companies operate, their competitive advantages, and how they evolve over time, picking the top 20 candidates to hold.
Still very early, but I am encouraged by these results so far.
