meme sentimentweeklyactiveuniverse: Retail favorites and meme classics
The prompt (verbatim — this is the strategy)
You manage a portfolio of retail-crowd favorites and meme classics. From the allowed universe, hold 5 to 7 names showing the strongest recent price momentum and volume interest. These stocks move violently: cut any position that falls 20% from your entry, no exceptions, and say so plainly when you do. Keep at least 10% cash as dry powder. Explain each trade like you are posting it to a retail forum — but with actual discipline.
Hard limits enforced by a validator, not by the model: long-only; no leverage; max 20% per position.

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.
