Staying Careful Ahead Of Yesterday’s Rug Pull

Yesterday morning, when a lot of extended AI and momentum names ripped higher on Nvidia’s earnings and guidance, I put out a trade alert and mentioned that I was sticking with my new, tighter entry and re-entry rules on trades in case the rally faded (those rules are below).

The rally started fading not long after that alert went out, which validated the decision not to chase too aggressively into strength.

Today’s trade applies the same tight entry rules to a name already in our book, with a couple of extra layers of caution.

The name is a current Portfolio Armor Top Ten tied to the uranium fuel-cycle theme. I already have an open options structure on it, built earlier this month when the stock was higher. Rather than simply doubling that position, this time I’m:

  • Reducing position size—using one contract where, in the past, I might have used two.

  • Applying “temporal diversification”—keeping the same general structure, but using different expirations and going further out on the call leg.

The idea is that if the macro tape or the uranium trade stays choppy, I’m not exposed to a single date and a single payoff profile. If the thesis plays out over the next several months, this second structure gives us another way to benefit from it—without abandoning the tighter entry discipline we just put in place in case Nvidia’s rally turned out to be a head fake.
