Laddering cash-secured puts: buying a stock in steps

A put ladder spreads one buying plan across several puts: a few strikes, a few expiry dates. If the stock dips a little, you buy a little. If it falls a lot, you buy more, at lower prices. It's averaging in, with a premium on each step.

The short answer

Laddering means selling more than one cash-secured put on the same stock, with different strikes and different expiry dates. Each put is one rung. Each rung needs its own cash: strike × 100.

The idea is to build a position in steps. A small dip fills the top rung. A deeper drop fills the lower ones. You end up with an average cost spread across several prices, instead of one bet at one price on one day.

It's a way to start the wheel strategy on a stock you'd like to own more than 100 shares of.

Why ladder instead of one big put?

• You don't have to pick the one perfect strike. Some rungs sit close to the price, some far below.
• Your buys spread over time. Different dates mean you're not all-in on one expiry day.
• A big drop buys more at lower prices. That's averaging in, done on purpose.
• Each rung pays its own premium while it waits.

The catch: all the rungs are the same stock. A ladder spreads your prices. It doesn't spread your risk.

Building a ladder (an illustration, not a trade idea)

A made-up stock, XYZ, trades at $50. You'd like to own up to 300 shares, and you'd rather buy lower. You build three rungs:

The farther-out dates help the lower strikes pay something. The higher strike is filled soonest if XYZ dips.

What happens at different prices

To keep the math clear, say XYZ reaches a price and stays there through all three expiry dates.

At $40, you own 300 shares at an average strike of $45. After the premiums, your cost is about $43.80 a share.

Compared with buying all at once. Here's the same $40 drop, three ways to buy 300 shares:

The ladder and the plain puts both beat buying at $50 on a drop. The ladder's real edge shows on the small dip. At $46, three $45 puts would all expire, with no shares bought. The ladder bought 100, the amount you wanted at that level.

Flip it around, and the cost is clear too. If XYZ jumps to $60, the share buyer is up $3,000. The ladder kept $360 and owns nothing.

The catches

1. One stock, all the risk. Three rungs on XYZ is still a bet on XYZ. If the business breaks, every rung fills on the way down. Size the whole ladder as one position.
2. The cash adds up. $13,500 here. That's cash not doing anything else until each rung ends.
3. More trades, more costs. Each rung has its own spread, fees and decisions. Small premiums on far rungs can lose a real part to the bid-ask gap.
4. Earnings may fall inside a far rung. A 60-day put often spans a report. Check every rung's date, not just the first.
5. Averaging down only helps if the stock comes back. Buying more of a falling stock lowers your average. It also raises your total at stake.

How to build one, step by step

1. Decide the most shares you'd own, and the total cash that takes. That's the ladder's size.
2. Pick a top rung close enough to fill on a normal dip. Our out-of-the-money puts guide helps with delta.
3. Space the lower rungs at prices you'd be glad to add at, not just round numbers.
4. Stagger expiries so the rungs don't all end on one day. Check each date against earnings.
5. Use the options chain to check each rung's bid-ask spread.
6. Write the exits for each rung before you sell. See cash-secured put exit rules.

A Canadian note: if you ladder inside a TFSA or RRSP, check that your broker allows cash-secured puts there. Options permissions differ by broker.
