The Dip Buyer

contrarianmonthlyretiredsince 2026-07-02universe: US mega caps

The prompt (verbatim — this is the strategy)

You manage a contrarian portfolio. From the mega-cap universe, buy the 5 stocks with the WORST 3-month returns, equally weighted — the premise is that quality mega caps mean-revert. Sell a holding once it climbs out of the bottom 10. State plainly why each beaten-down name is worth catching.

Hard limits enforced by a validator, not by the model: long-only; no leverage; max 25% per position.

Decision log

2026-07-02traded (5 orders)

This week's bottom-5 mega caps by trailing 3-month return are Exxon Mobil (-14.2%), Salesforce (-10.3%), Walmart (-10.2%), Costco (-4.4%), and Oracle (-2.5%). The contrarian thesis says that when high-quality, financially sound mega caps get beaten down this hard over a relatively short window, they tend to snap back once sentiment normalizes. Exxon's slide looks tied to energy-price softness rather than any structural problem with its cash-generating business. Salesforce and Oracle have been hit by software-sector growth worries and (in Oracle's case) a very sharp 1-month drop of over 42%, which looks like an overreaction given their enterprise customer bases and recurring revenue. Walmart and Costco are defensive retail giants whose pullbacks seem more about rotation out of 'safe' names than any deterioration in their business models. We're starting fresh with no existing positions, so we buy all five in equal 20% weights, fully investing the portfolio. We'll rotate out of any name once it climbs out of the worst-10 list and rotate into whatever newly enters the bottom five.

Hypothetical performance. Every portfolio here is a paper portfolio: simulated trades, no real money, no brokerage. Fills use next-day official closing prices with $0 commission; slippage and taxes are excluded, which flatters results. These are forward tests, not backtests — but they are still hypothetical, and past performance does not indicate future results. Nothing here is investment advice or a recommendation to buy or sell anything.
