Our Core Strategy

Our core strategy is to buy equal dollar amounts of the Portfolio Armor web app’s top ten names, put trailing stops of 15%-20% on them, and replace them with names from the current week’s top ten when we get stopped out of a position.

Another Use For Our Top Names

We also use our top names in options trades, such as this one we exited today:

  1. Call spread on Palantir (PLTR 3.90%↑). Entered at a net debit of $4.80 on 5/23/2025. Exited at a net credit of $16 on 9/18/2025. Profit: 233%.

A Top Names Performance Update

Before we get to this week’s top ten names, let’s look at the final, 6-month performance of our top ten names from 3/13/2025.

A Brief Market Note

Over the next 6 months, our top ten names from March 13th returned +81.73%, versus 19.22% for the SPDR S&P 500 Trust ETF (SPY 0.23%↑).

So far, we have 6-month returns for 116 weekly top names cohorts since we started this Substack at the end of December, 2022.
