Uncovered (Naked) Option Writing

All the strategies covered so far involve paired positions that limit risk. Now we turn to uncovered (naked) writing: selling options without a corresponding stock position or offsetting option. These strategies offer limited gain potential with potentially devastating losses.

Uncovered Call Writing (Equity Options)

• Structure: Selling a call option without owning the underlying stock
• Market outlook: Neutral to moderately bearish (expects the stock to stay flat or decline)
• This is the highest-risk options strategy

• If the stock rises above the strike, the writer must buy shares at the market price to deliver at the strike price
• Since the stock can rise without limit, the loss is unlimited
• Requires a margin account and significant margin deposits
• Brokers require the highest level of options approval for this strategy

Think of it this way: You sold someone the right to buy stock from you, but you don't own the stock. If the price skyrockets, you have to go buy it at the market price and hand it over at the lower strike price. The higher it goes, the more you lose, with no ceiling.

Example: Sell 1 XYZ Oct 60 call at 4 (no stock owned)

• Max gain = $4 (stock at or below $60)
• Max loss = Unlimited (stock can rise to any level)
• Breakeven = $60 + $4 = $64
• If XYZ goes to $100, the writer loses ($100 - $60) - $4 = $36 per share

Exam Tip: Gotchas

• Uncovered call writing is the single highest-risk options strategy. The exam frequently asks which strategy carries unlimited risk. Short uncovered calls and short stock are the two positions with unlimited loss potential.
• The breakeven for an uncovered call is Strike + Premium. The writer starts losing money only after the stock rises above this level.

Uncovered Put Writing (Equity Options)

• Structure: Selling a put option without a short stock position or sufficient cash/margin to cover
• Market outlook: Neutral to moderately bullish (expects the stock to stay flat or rise)
• Less risky than uncovered calls because the stock can only fall to zero

Example: Sell 1 XYZ Oct 60 put at 4 (no short stock position)

• Max gain = $4 (stock at or above $60)
• Max loss = $60 - $4 = $56 (stock goes to $0)
• Breakeven = $60 - $4 = $56

Exam Tip: Gotchas

• Uncovered put writing has LIMITED (not unlimited) risk. The stock can only fall to zero, so max loss = Strike - Premium. This is a common exam distinction from uncovered calls.
• Breakeven and max loss use the same formula for uncovered puts: Strike - Premium. The number is the same, but they mean different things (breakeven is the stock price where you start losing; max loss is the total dollar loss if the stock hits zero).

Uncovered Index Option Writing

• Assignment results in a cash payment obligation, not delivery of securities
• The multiplier applies: an index at 4,500 with a $100 multiplier = $450,000 notional value
• Broad-based index options are European-style, which means they can only be exercised at expiration (reducing the risk of unexpected early assignment)

Exam Tip: Gotchas

• Index options settle in cash, not securities. If assigned on an uncovered index call, you owe a cash payment based on the difference between the index level and your strike, multiplied by $100. There is no stock delivery.
• European-style does NOT mean risk-free. It only means the holder cannot exercise early. The writer still faces the full risk at expiration.

Uncovered Yield-Based (Interest Rate) Option Writing

Yield-based options are based on the yield of Treasury securities, not their price. The most commonly tested is the TYX, which tracks the 30-year Treasury bond yield.

Key characteristics:

• European-style and cash-settled
• Multiplier is $100
• Strike prices reference yield levels (e.g., a TYX 35 call references a yield of 3.5%)

Critical relationship: yield-based options move OPPOSITE to bond prices

Uncovered yield-based writing risks:

• Uncovered yield-based call writing: Substantial risk if yields rise significantly
• Uncovered yield-based put writing: Substantial risk if yields fall significantly (though yields cannot go below zero)

Hedging application: A bond portfolio manager worried about rising interest rates should buy yield-based calls to hedge. As rates rise, bond prices fall, but the yield-based call gains offset the loss.

Think of it this way: Yield-based calls are the mirror image of regular bond calls. A regular bond call profits when bond prices rise. A yield-based call profits when yields rise (which means bond prices are falling). The word "yield" flips everything.

Exam Tip: Gotchas

• A yield-based call is NOT the same as a bond call. It profits when rates RISE (and bonds fall). This is the most commonly tested distinction for yield-based options.
• Hedging a bond portfolio against rising rates = buy yield-based calls (not puts). Rising rates hurt bond prices, but the yield-based call gains offset that loss.
• Reading TYX strike prices: Place a decimal between the first and second digits. A TYX 35 call references a yield of 3.5%, not 35%.
