The wheel strategy with $100,000: caps matter more than picks

With $100,000 you can wheel many names, including big index ETFs. The danger moves from "not enough room" to "too much room." One stock you love, sized too big, can undo everything else.

The short answer

With $100,000 you can run the wheel strategy across eight to fifteen positions, and even the largest index ETFs become possible. Each cash-secured put still needs the strike times 100 in cash.

At this size, position caps matter more than stock picks. A good list of stocks won't save an account where one name is a third of the money. A plain list with firm caps usually holds up better. The example below shows why.

A worked example where one name breaks the account (an illustration, not a trade idea)

Two sellers each have $100,000. They wheel the same watchlist of made-up stocks. The only difference is one cap.

• Seller A has no cap. XYZ is their favourite. It trades at $100 after a small dip, and its puts pay well. They sell four 30-day puts at the $95 strike for $2.50 each. That's $1,000 collected and $38,000 set aside: 38% of the account.
• Seller B caps any one name at 10% of the account. They sell one $95 put for $2.50: $250 collected, $9,500 set aside.

Both spread the rest of their money across other names the same way. So the rest of the two accounts behave the same.

Then XYZ gets surprise news between earnings. It drops to $60 by expiry. Both are assigned at $95.

Over the next two months, XYZ slides to $50. Each month, both sell calls at the $95 strike so they won't sell below cost. Those calls bring only $0.20 each.

Seller A didn't pick a worse stock. They picked the same one. The size did the damage. And the big put premium that made XYZ look attractive was the market's way of saying it expected a big move.

At $100,000, that's the risk that matters most. Not running out of room, but having too much of it.

The portfolio view

With many positions, it helps to stop looking at trades one at a time and look at the whole book. Once a week, write down five numbers:

1. Total cash set aside for open puts.
2. Total value of shares held from assignments.
3. Cash free that backs nothing.
4. The largest single name, as a share of the account.
5. The largest single industry, as a share of the account.

Then ask one question: if everything fell 25% below its strike tomorrow, what would the loss be?

Here's a rough version (an illustration, not a forecast). Say $80,000 backs puts or shares across ten names, and $20,000 is free cash.

That last row is the honest worst normal case for a fully used wheel book. Caps don't make it go away. They make sure no single name, or single industry, adds a second disaster on top of it.

Caps that matter at this size

• Per name. At this size, a cap somewhere between 5% and 10% of the account leaves room for many names. Write yours down.
• Per industry. Banks, chip makers, oil producers and airlines tend to fall together. Count them as one group. See diversifying a wheel portfolio.
• Per expiry date. If a third of your puts expire on one Friday, a bad week hits a third of the book at once. Stagger dates.
• Unused cash. Keep a fixed share that never backs a trade. See keeping cash aside for assignment.
• No adding after a drop beyond the cap. The moment a falling stock's puts look cheap is the moment the cap exists for.

These are the same ideas as at $25,000, with more names. See the wheel with $25,000 and position sizing for selling options.

Where big index ETFs fit

At $100,000, a put on the largest index ETFs becomes possible. But do the math first. Those funds trade at several hundred dollars a share, so one put sets aside tens of thousands of dollars. Depending on the price, that can be half the account or more in one position.

It's one position in a fund that holds hundreds of companies, so it's not the same as half the account in one stock. But it still falls with the market. Check the current price, decide what share of the account it should be, and size from that. See the wheel strategy on SPY.

A note on accounts. In the US, many brokers allow covered calls in an IRA, and some allow cash-secured puts there. In Canada, covered calls are widely allowed in a TFSA or RRSP, while cash-secured puts depend on the broker. Options permissions differ by broker. At this size, ask your broker how margin rules apply, even if you only plan to sell cash-secured.

The rule for next time

Set the cap before you look at the premium. The premium on a name you love will always tempt you to go bigger, and it's highest exactly when the stock is most likely to move. Decide the most one name can take, write it down, and treat it as fixed.

Nothing Seller A did was unusual. They found a stock they liked at a dip, and sold more of it. That's a normal urge. A written cap is how you stop it from turning a bad stock into a bad year.
