This Altimetry review examines Joel Litman’s retail research service and the institutional engine behind it. Most investment newsletters are written by journalists who read annual reports. Altimetry is written by a forensic accountant who rewrites them.
Joel Litman is a CPA, a CFA charterholder, and a Certified Fraud Examiner. He lectures at Harvard Business School, Wharton, and Chicago Booth. He consults for the FBI and the Pentagon. His institutional research firm, Valens Research, counts all ten of the world’s largest money managers as clients — firms that pay up to $100,000 per month for his team’s analysis.
This is the opposite of the typical background for a retail stock-picking service.
Altimetry is the consumer arm of Valens Research. The dark energy SpaceX $10T boom thesis is its current flagship campaign; the Altimetry hidden alpha service page covers the product, with the same team, same methodology, and same database covering thousands of companies. The difference is distribution: institutions get API-level access and custom reports, retail subscribers get curated picks and daily commentary at a fraction of the institutional price. The underlying research engine is identical. For a focused trust check, the Hidden Alpha review grades the service on its own terms.
What You Actually Get
Altimetry operates several products under one roof.
Hidden Alpha is the flagship monthly newsletter. One in-depth large-cap stock recommendation per month, backed by the full Uniform Accounting analysis, the Altimeter grade, and earnings call forensics. Subscribers also get the Altimetry Daily Authority, a weekday market briefing. Current introductory price is $79 for the first year, renewing at $199 against a regular list price of $499.
High Alpha focuses on the most extreme mispricings — smaller, less-followed names where the Uniform Accounting signal is strongest and the market awareness gap is widest.
Breakout Profits layers momentum analysis on top of the fundamental work. Uniform Accounting provides the “what to buy” signal; a quantitative timing system handles the “when to buy.”
Altimetry Daily Authority is the free weekday briefing. It’s the best window into the methodology without paying anything. Litman and director of research Rob Spivey write most of the analysis. It’s substantive — real numbers, real accounting adjustments, real conclusions.
The common thread across all products is the data engine. Altimetry’s team of over 100 analysts and accountants reviews more than 6,500 companies every quarter. They fix errors in as-reported financial statements — thousands of corrections every month — then restate everything to Uniform Accounting standards. No other retail research service does this.
The Core Mechanism
Standard accounting allows companies to report the same economic reality in different ways. Depreciation, lease accounting, revenue recognition, goodwill impairment — over 130 reporting choices exist within GAAP. Two identical businesses can report radically different earnings depending on how they categorize things.
Wall Street analysts build models on top of these numbers. The distortions compound.
Uniform Accounting strips every company’s financials back to a single standard. Depreciation gets recalculated uniformly, operating leases get treated as capital expenditures, and goodwill gets removed from asset calculations. The result is a financial statement that can be compared apple-to-apple across any company, any industry, any time period, and any accounting regime — including Chinese standards versus US GAAP.
Litman’s team then runs every stock through the Altimeter, a proprietary grading system that rates stocks A through F. An A-rated stock has strong Uniform profitability and low market expectations — the gap the strategy exploits. F-rated stocks have weak fundamentals and high expectations — the short candidates.
The research record bears out the process. Litman called the 2008 financial crisis months in advance, reading the warning signals in corporate credit markets before the broader market caught on. He called the COVID bear market and the subsequent K-shaped recovery in March 2020, when most analysts were predicting prolonged depression. Those calls came from the same methodology, not from lucky macro guesses.
The stock-level track record is more striking. According to Valens Research’s institutional client recommendations, Meta (then Facebook) was flagged in 2012 before a 1,400% run. In a 2015 Bloomberg interview, Litman argued AMD “should soar” — the stock went on to deliver roughly 7,100%. According to Litman’s published research, Novavax delivered over 3,000% during the pandemic.
Since the start of 2024, Altimetry reports that subscribers have had the opportunity to double their money on 20 separate occasions across the platform’s research products. According to Altimetry’s published track record, the average gain per recommendation over the past two years is 26%, versus 10.7% for the S&P 500. The Hidden Alpha model portfolio has returned over 120% since inception.
These numbers are published, tracked, auditable trade records. Past performance does not guarantee future results. The returns cited are based on Altimetry’s published track record and model portfolio; actual subscriber results may differ.
What to Consider Before You Subscribe
Three things matter for context.
First, the track record includes real losers. Illumina was a Hidden Alpha pick in 2022 that fell over 60% from the recommended buy price. Ginkgo Bioworks dropped significantly. A review of the closed positions portfolio shows about half of the closed-out picks took losses. That’s normal for a real investment process — no one bats 1.000. But anyone buying the service should understand that a 26% average gain over two years includes the losers.
Second, the methodology works best in specific market regimes. Uniform Accounting identifies companies where reported earnings understate real economic performance. That signal is most powerful in recovery environments and least powerful in momentum-driven markets where price action decouples from fundamentals. The 2022 drawdown in several Hidden Alpha picks coincided with a rate-driven selloff that punished fundamentals-based strategies broadly.
Third, the marketing is aggressive. The current “Dark Energy” campaign is heavily branded. The packaging temperature is higher than the research temperature. This is common in the newsletter industry, and Altimetry is better than most at separating the two — but new subscribers should evaluate the research itself, separate from the packaging.
Is Altimetry Worth It?
Altimetry is an institutional research operation that happens to sell a retail subscription.
The distinction matters because it changes how you evaluate the product. A tip service is a black box — you get a stock ticker and a paragraph of justification, and you trust or don’t trust the track record. Altimetry gives you the entire process: the accounting adjustments, the corrected financial statements, the earnings call transcripts, the reasoning. You can verify the work yourself. The methodology is transparent even if the specific patented calculations are not.
The institutional clients paying six figures per month have their own analysts. They pay for clean, corrected, standardized financial data — the raw material that their internal models run on. Altimetry’s retail subscribers get the output of that same data engine.
A 26% average gain versus 10.7% market over two years, a model portfolio at +120%, three massive multi-bagger calls that predate the retail newsletter’s existence, two correct macro calls on the two biggest market dislocations of the past 20 years — that is a track record that carries weight even with the losses accounted for. Past performance does not guarantee future results; the returns cited are based on Altimetry’s published track record and model portfolio, and actual subscriber results may differ.
The question is whether you want your investment research from a journalist or from a CPA who fixes the numbers before he reads them.
