Model Portfolio Stocks: How the 401(ai) Is Built

Model portfolio stocks are the product every financial newsletter ultimately sells, and Marc Chaikin’s new 401(ai) presentation is one of the cleanest specimens we have examined in this cycle: five stocks, a defined selection mechanism, explicit exit criteria, and a deliberately small size. Most model portfolios in this genre are long lists with a story attached. This one is the reverse: a short list with a system. We read the presentation end to end. Our full 401(ai) teardown covers it in detail.

Why Five Stocks

The size is the design’s most distinctive choice, and the pitch defends it directly: “I don’t want somebody who’s already nervous about retirement trying to choose among 40 different stocks across five different AI sectors. That’s how people end up doing nothing.” That is a real insight about the audience the pitch targets: near-retirees who are, in the pitch’s own words, “afraid to buy and then also afraid not to buy.” A forty-name portfolio is a full-time job. A five-name portfolio is a decision.

The names themselves are membership content, but the pitch describes what each entry includes: “why it earned its place, what the Power Gauge is seeing… and what would have to change for me to take it out.” That last clause is the one most portfolios omit. A stock with a written exit condition is a position with an owner; a stock without one is a hope with a ticker.

The Selection Mechanism

The system behind the list is the Power Gauge, Chaikin’s 20-factor rating engine: “Some are tied to the company’s financials. Others look at price activity, analyst behavior and money flow.” Chaikin’s reframe: “I think of them more like 20 witnesses.” The output is a simple bullish, neutral, or bearish rating, and the portfolio’s rule is to hold five names the witnesses agree on, positioned for what the pitch calls the upper arm of the K, the companies whose economics AI improves.

The historical demonstrations of the system, offered with dates: Occidental (OXY) rated bullish January 14, 2022, before Berkshire’s purchases; Vertiv (VRT) bullish April 2023, before a climb of more than 727% and institutional follow-on (“Ray Dalio established a new 60,000 share position. Ken Griffin of Citadel increased his position by 258%. Vanguard added 3.4 million shares worth over a billion dollars”); Lumentum (LITE) bullish August 2025, before a climb of as much as 753%; AppLovin (APP) at $13 in March 2023. The thesis the portfolio implements: “I’m not investing in AI. I’m investing in what AI does to the numbers.”

The Two Halves Around the List

What makes the 401(ai) a portfolio rather than a flyer is what surrounds the five names. The “Five Stocks to Sell Now” companion report applies the same screen to the falling arm, with the pitch’s line for the discipline of exits: “the most expensive four words in investing can be, I’ll just hold on, especially when the reason you bought the stock no longer exists.” We look at the sell list in detail here. And the “401(ai) Waiting Room” publishes the eight companies that just missed, each with “the specific missing signal” that would earn promotion. A model portfolio that shows you its bench is inviting verification, which is a better posture than a list that pretends certainty.

The honest caveat on the demonstrations: every historical example is a winner shown after the fact, the sole volunteered loser is Braze, down about 25% from its rating, and the hypothetical basket’s 137% figure carries the pitch’s own disclaimer: “These results are not typical nor indicative of future performance.” Our Power Gauge explainer covers the 20 factors in detail.

Who This Suits

A five-stock AI-tilted portfolio is a concentrated bet, and the pitch is aimed at savers who currently hold diversified index funds, so the honest framing is about allocation: the pitch’s own language is “to keep a portion of your money focused on the upper arm of the K,” a portion, not the whole account. The 30-day full refund (“for any reason or for no reason at all”), the monthly updates, and the explicit rotation possibility (“Six months from now, the stocks may be different”) make the product a research subscription, not a managed account: “I don’t manage people’s money anymore… And I cannot give you individualized investment advice.”

What You Get

The complete package: the 401(ai) report with the five names and rationale, the sell report, the waiting room, and updates “when the evidence materially changes.” Value anchored over $2,000, actual price behind the order-page click. Details in the presentation. The full offer anatomy is in our 401(ai) overview, and the frame behind the picks is in our K-shaped economy explainer.

The Honest Read

Model portfolio stocks are only as good as the mechanism that picks them and the discipline that retires them, and the 401(ai) is unusually explicit about both. The mechanism’s past is verifiable in its rating dates; its future is the open question every subscription asks. For a near-retirement buyer, the five-name design is the feature that matters most: small enough to actually follow, which is exactly what the pitch says out loud. That candor is worth something in a genre not known for it.
