You’ve got a view on a stock. Not a wild one — you think it grinds higher over the next month or so, nothing dramatic. So you buy a call. But paying for that call feels backwards to you, because you’re an option seller. You like collecting premium, not handing it over. What if you could keep your directional bet and still get paid to make it?
What a Ratio Spread Actually Is
A ratio spread options strategy is simple in concept, even if the name sounds complicated. You buy one option at a strike close to the current price, and you sell more than one option — usually two — at a further strike in the direction you expect the stock to move.
The extra option you sell brings in more premium than the one you buy costs. That’s the whole trick. Instead of paying for a directional bet, you structure it so the market pays you to take it.
Why This Beats Just Buying a Call
Buying a naked call is a bet that needs to be right fast and needs to be right big. Time decay works against you every single day you hold it. A credit ratio spread flips that relationship — now decay can work for you on the extra short leg, especially once the stock gets near your target strike.
You’re not just predicting direction anymore. You’re getting compensated for the accuracy of your prediction, upfront, in cash. That’s directional options trading with a very different risk profile than most business owners were taught when they first learned about calls and puts.
So why doesn’t everyone build every directional trade this way? Because there’s a catch — and it’s one worth understanding before you place a single contract.
The Trade-Off Nobody Talks About
Here’s the part that gets glossed over in the excitement of collecting a credit. That extra short call you sold isn’t fully covered. One of your two short options is backed by the long call you own. The other one is naked.
If the stock rips far past your short strike, that uncovered option starts working against you — and the loss isn’t capped the way a normal credit spread’s loss is capped. This is the honest trade-off: you get paid to make a directional call, but if you’re wrong in a big way, the position can hurt more than a simple debit spread ever would.
That doesn’t make the strategy bad. It makes it a tool for a specific kind of view — one where you expect the stock to move toward a level and then stall, not blow through it. Let’s put real numbers on this so it’s not abstract.
A Worked Example
Say a stock is trading at $50. You think it drifts higher over the next 45 days, maybe settling somewhere near $55, but you don’t expect a runaway move.
- You buy 1 call at the $50 strike for $2.20 (cost: $220)
- You sell 2 calls at the $55 strike for $1.20 each (credit: $240)
- Net result: you collect a $20 credit just to put the trade on
If the stock sits at or below $50 at expiration, everything expires worthless and you keep your $20 credit. If it climbs to exactly $55, your long call is worth $500 and your short calls expire worthless — your profit is roughly $520, the sweet spot of the trade.
But if the stock keeps running past $55, that extra naked short call starts eating into gains fast. In this example, the trade’s breakeven on the upside sits around $60.20. Push past that, and losses grow the further the stock runs — with no hard ceiling on how far it can go against you.
Where a Credit Ratio Spread Actually Fits
This isn’t a trade for “the stock might do anything.” It’s a trade for “I think it goes here, and probably not much further, at least not soon.” That’s a specific, narrower kind of conviction than most directional traders admit to having.
- Use it when you have a target level in mind, not just a general direction
- Favor it when implied volatility on the further strike is rich relative to the near strike — that’s what funds your credit
- Size it smaller than a defined-risk spread, since the uncapped side needs room for error
- Have a plan for what you do if the stock blows through your short strike before expiration — don’t wait until it’s already a problem
Skip it when you have no real view on where the move stalls, or when you’re not willing to actively manage the position if it runs hot. Getting paid upfront feels good. It stops feeling good if you’re not watching the trade.
The Takeaway
A ratio spread lets you collect options premium on a directional idea instead of paying for one — but only if you respect the uncapped risk on the extra short leg. Before you put one on, know your target level, size it small, and decide in advance what you’ll do if the stock runs past your short strike.
Options selling carries real risk of loss, including potentially significant loss on strategies with uncapped risk like ratio spreads. This article is for education only and isn’t personalised financial advice.
