Bear with me on this one.
It’s 1992. You’re ten years old.
Your friend Jake walks up to you on the playground and says:
“Hey. I’ll give you $100 today. You give me back $105 next year. Deal?”
You think about it for exactly four seconds.
Because you’ve been eyeing a rookie Ken Griffey Jr. card at the card shop for $100. And you know – you just know – that thing is going to be worth more by next summer.
So you say deal. You shake on it. You go buy the card.
A year later it’s worth $110. You owe Jake $105. Instead of selling the card, you walk up to him and make another offer.
“Hey Jake. What if I just borrow the $105 again instead of paying you back? I’ll owe you $110.25 next year.”
Jake shrugs. Deal.
Your card keeps sitting in your collection. Growing. Year two it’s worth $121. You owe Jake $110.25. You make him the same offer again. Year three. Year four. Year five.
Every year your card grows faster than what you owe Jake. Every year you roll the loan and keep the card working.
That gap – between what your investment earns and what the loan costs – compounds quietly in your favor.
That’s the whole game.

Now fast forward 30 years. Same concept. Different instrument. It’s called a box spread.
Inside your brokerage account, you buy and sell four options contracts in a specific combination that cancels out all market risk. No matter what the stock market does, the box pays back a guaranteed fixed amount at expiration.
Because the outcome is guaranteed, you can borrow at very low rates – 4-5% when a bank or HELOC charges 7-9%.
The cash lands in your account. You put it to work. If the portfolio earns 8-10% and you borrowed at 4-5%, you keep the spread. When the loan comes due, you roll it. Just like you did with Jake.
Portfolio stays fully invested. Box gets renewed. The spread keeps compounding in your favor.
Financial Zen added this to our strategy early last year for a select group of our Members.

Here’s what most people don’t realize: this isn’t new.
Family offices and institutional investors have been doing versions of this for decades. Borrow cheap, invest smart, keep the spread, roll the loan. It’s been a cornerstone of sophisticated wealth management forever.
What is new is access.
Historically the math just didn’t math unless you had millions. Electronic options markets changed that – and today, through our partners at SyntheticFi, you can execute a box spread loan with as little as $10,000.
We’re not inventing anything. We’re just finally on the right side of the velvet rope.
