The wheel: cash-secured puts, covered calls, cost-basis tracking and its weaknesses

What you will learn

• The mechanics of the wheel: cash-secured put, assignment, covered call, call-away.
• How to keep a cost-basis ledger that shows your real break-even at every stage.
• How to state premium yields honestly.
• In which markets the wheel underperforms buy-and-hold, and why.

Explanation

The wheel is a repeating cycle. Step 1: sell a cash-secured put on a stock you would be willing to own, holding enough cash to buy 100 shares at the strike. Step 2: if the put expires worthless, sell another; if assigned, you own the shares. Step 3: sell a covered call above your cost basis. Step 4: if the call is assigned, the shares are called away and you return to step 1. Single covered calls were covered in the course Derivatives: Futures, Options, CFDs and Certificates and covered-call ETFs in the course Dividend & Income Investing; here the wheel is a managed process with a ledger.

The cost-basis ledger

Your adjusted cost basis is the assignment strike minus every premium received in this cycle (plus any premium paid to buy options back). It tells you which call strike locks in a profit. Keep it per cycle: date, action, strike, premium, running basis.

Honest yield arithmetic

Period yield = premium / cash secured (or / cost basis for a call)

Annualising (multiplying by 365 / days) helps compare trades, but it assumes the same conditions repeat all year. The period yield is the only one you have actually earned.

Where the wheel loses to buy-and-hold

• Strong rallies: an unassigned put earns only the premium; a covered call caps the gain at the strike. When a stock rises 30 percent in a year, a wheel often earns a small fraction of that.
• Sharp declines: the premium cushions only a few percent; below that you hold the full loss, and calls above your basis then pay almost nothing. Many wheel accounts end up "stuck" in fallen stocks.
• Taxes and costs: premiums, assignments and share sales are separate taxable events in Germany (general orientation in the course Derivatives; check with a Steuerberater), and every cycle pays spreads and commissions.

Through the Greeks, the wheel is permanently short volatility and long the stock: steady small gains in sideways markets, large give-backs in both tails. A legitimate trade-off, not a free lunch.

Rules of thumb

• Only wheel stocks you would hold through a 30 to 50 percent decline; the strategy does not protect you from one.
• Sell puts at roughly 0.20 to 0.30 delta, 30 to 45 DTE, and calls at or above your adjusted basis.
• Close a short option at 50 to 70 percent of maximum profit when that happens early.
• Avoid selling calls through earnings or just before an ex-dividend date if you want to keep the shares (lesson 10).

Worked example

Hypothetical example: stock at $50.00. You sell one 45-DTE 47 put at 1.20 and hold $4,700 as collateral. Interest on cash, commissions and taxes are ignored.

Step 1, yield: 1.20 / 47 = 2.55 percent for 45 days; annualised 2.55 x 365 / 45 = 20.7 percent, if conditions repeated all year, which is not guaranteed.

Step 2, assignment: the stock is at $46 at expiry. You buy 100 shares at $47 = $4,700. Adjusted cost basis = 47.00 - 1.20 = 45.80, so you are 0.20 above basis despite being 1.00 below the strike.

Step 3, covered call: with the stock at $46 you sell a 30-DTE 48 call at 1.40 (above basis). New basis 45.80 - 1.40 = 44.40.

Step 4, call-away: on day 75 the stock is at $49.50 and the shares are called away at $48. Profit = 48.00 - 44.40 = 3.60 per share, $360 on $4,700 = 7.7 percent in 75 days.

Buy-and-hold from $50 to $49.50 over the same 75 days: -1.0 percent. The wheel won because the stock dipped and only partly recovered: the ideal wheel path.

Rally path: the stock rises to $58 by day 45; the put expires worthless and you earned 2.55 percent while buy-and-hold earned 16 percent. Crash path: the stock falls to $35 by day 75; the wheel loses 35.00 - 44.40 = -9.40 per share (-$940) against -15.00 (-$1,500) for buy-and-hold. The wheel softens the fall but does not prevent it, and from $35 any call above 44.40 pays almost nothing.

Common mistake

Practice activity

On paper: a stock trades at $80. You sell a 40-DTE 75 put at 1.60 and are assigned with the stock at $73. You sell a 30-DTE 78 call at 1.10; it expires worthless at $76. You sell another 30-DTE 78 call at 1.30 and are called away at $78. Build the ledger, compute the profit per share and in dollars, the return on $7,500 of capital, and compare with buy-and-hold from $80 to $78 over the same 100 days.

Key takeaways

• The wheel's result depends on the stock's path, not only on where it ends.
• Track the adjusted cost basis per cycle and sell calls above it.
• Quote period yields; annualised numbers assume a repetition that is never guaranteed.
• The wheel is short volatility: it beats buy-and-hold in sideways and mildly falling markets and loses in strong rallies and deep declines.
