The Rational Trader: Two Mean Reversion Setups: Best Buy and Nvidia

by | Aug 27, 2025

 

The “2 Sigma” setup that turns calm into cash

Hey everybody, JD here with your Rational Trader Market Analysis daily.

We’re back in the Mean Reversion Cash Machine, ready to ring the register.

It’s been a quiet stretch, but that changes this week. I’ve got 10 names on my radar — and I’ve narrowed them down to two that I think offer the best juice for us right now.

Trade #1: Best Buy Call Credit Spread

The first setup is Best Buy (BBY), reporting earnings tomorrow morning.

On the chart, Best Buy is trading right around two standard deviations above its mean — what I call the “Two Sigma” level.

Quick plain-English refresher: Two Sigma just means the stock price has stretched unusually far from its recent average. Think of the mean as a magnet. The farther a stock gets, the stronger the pull to snap back.

With that in mind, I’m putting on a call credit spread — a trade where you sell a call option above the current price and buy another call at a higher strike to cap the risk. It’s a way to pocket premium up front, betting the stock won’t blast much higher.

Here’s how I’m structuring it:

  • Sell the $81 call (about 8% above the current price)
  • Buy the $86 call for insurance

That creates a $5-wide spread, giving me a $4 cushion above Two Sigma, and it caps my max loss at $5 per contract. If Best Buy reverts lower or even just stalls, I keep the credit.

Trade #2: Nvidia Reverse Iron Condor

The second setup is the big one: Nvidia (NVDA).

It’s the name everyone’s watching, with earnings after the close today. Premiums are huge, and the stock’s been trading right around its mean. That’s the perfect recipe for a reverse iron condor.

For those not familiar, a reverse iron condor is a four-legged options trade designed to profit if the stock makes a big move in either direction.

You buy a call and a put at the same strike, then sell another call above and another put below. It’s essentially a volatility play.

Here’s the structure I like:

  • Buy the $180 call
  • Buy the $180 put
  • Sell the $190 call
  • Sell the $170 put

This whole setup costs about $7.50.

If Nvidia moves plus or minus about 5%, the trade can pay out $10. In other words, we’re risking $7.50 to make $10 — a defined-risk bet that volatility delivers.

Wrapping It Up

So those are the two trades I’m lining up today: a call credit spread on Best Buy with earnings tomorrow morning, and a reverse iron condor on Nvidia with earnings after the close.

Both are mean reversion cash machine plays, and both give us a clean way to capture premium in a market full of juice.

That’s it for today, folks. Good luck with your trading. I’ll be back tomorrow to break it all down and bring you the next opportunity.
