Review of Profit Diagrams 1. Assumptions Profit is defines as: ending value – beginning value Time value is not considered (although it is simple to modify the diagrams for time value) Transaction costs not included (although they can be) Profit diagrams generally assume European options held to maturity A pricing model is needed to construct profit diagrams for positions closed prior to maturity 2. Adding Functions Using Graphs (Basic Technique) EXAMPLE 1 Page 3 of 11 Fin4328 (Moore) Trading Strategies with Options Summer 2006 Example 2 (fixed negative payoff) Example 3: Fixed payouts and Increasing Function Page 4 of 11 Fin4328 (Moore) Trading Strategies with Options Summer 2006 B. Combining A Single Option With the Underlying Stock Long Stock and Short Call (Writing Covered Call) minimizes downside risk on stock Long Call and Short Stock (Reversed Covered call) Long Stock and Short Put (Protective Put) Short Stock and Short Put (Reversed Protective Put) Page 5 of 11 Fin4328 (Moore) Trading Strategies with Options Summer 2006 Example: Rio Tinto – Current Stock Price = $32.40 per share Call or Put Call Options Put Options Price (C or P) C = 3.20 C = 0.99 C = 0.61 Strike Price X = 30.00 X = 34.00 X = 35.50 Maturity 29 Nov 29 Nov 29 Nov C = 3.52 C = 1.48 C = 1.04 X = 30.00 X = 34.00 X = 35.50 20 Dec 20 Dec 20 Dec P = 0.63 P = 2.50 P = 3.60 X = 30.00 X = 34.00 X = 35.50 29 Nov 29 Nov 29 Nov P = 0.87 P = 2.80 P = 3.83 X = 30.00 X = 34.00 X = 35.50 20 Dec 20 Dec 20 Dec Covered Call Using the 20 Dec. Call option with Strike = $34 (Long Stock and Short Call) Stock Price Range ST X S T $34 Profit Payoff From Long Stock ST ST - S0 S T – $32.40 Payoff From Short Call X - ST $34 - S T X + C0 - ST 34 + 1.48 - S T ST X S T $34 Profit ST $0 ST - S0 S T – $32.40 <0 C0 $1.48 Breakeven Price is $30.92 Page 6 of 11 Total Payoff X $34 X + C0 - S0 35.48 - 32.40 = 3.08 ST ST - S0 + C0 S T - 30.92 Fin4328 (Moore) Trading Strategies with Options Summer 2006 C. Spreads – Options of same type with different X (Strike) or T (Assume 2 calls with same maturity, X1 < X2 ) 1. Bull Call Spread - Buy C(X1) , Sell C(X2) where X1 < X2 Has initial Cash Flow (CF), profits from increase in price Calls may initially be: 1) in-the-money; 2) out-of-themoney; or 3) 1 in and 1 out (both out is riskiest, highest potential returns) Can also be constructed with puts (Buy P(X2) , Sell P(X1)) Put Spreads have + initial CF, But lower payoffs Page 7 of 11 Fin4328 (Moore) Trading Strategies with Options Summer 2006 2. Bear Call Spread - Buy C(X2) , Sell C(X1) Opposite of Bull Spread (mirror image) Can be constructed with puts (Sell P(X2) , Buy P(X1)) Bear call Spread Bear Put Spread 3. Butterfly Spreads 3 Different Strike Calls (or Puts): X1 < X2 < X3 Buy C(X1), Buy C(X3), Sell 2 C(X2) Butterfly spreads can also be reversed Transaction costs can be large (4 Options total) For European Options, exactly the same profits will be obtained by using puts instead of calls Page 8 of 11 Fin4328 (Moore) Trading Strategies with Options Summer 2006 4. Calendar (Time) Spreads Use two different maturities (Same Strike): T1 < T2 Buy Long Maturity, Sell Short Maturity Profit is defined at maturity of short maturity option Diagram is not linear since the profit depends on the market value of the long maturity call Profit at maturity of short maturity option (T1) is positive if the stock price is near the strike price A Loss results if the stock price is substantially above or below the strike at time T1 Page 9 of 11 Fin4328 (Moore) D. Trading Strategies with Options Summer 2006 COMBINATIONS of CALLS AND PUTS 1. Bottom Straddle – Buy Call, Buy Put (Same Strike, T) Profits from a large increase or decrease Note: High Volatility means cost of both options will be high, and large price changes may be needed for profits Bottom Straddle 2. Top Straddle – Sell Call, Sell Put (Same Strike, T) Opposite (Reverse) of Bottom Straddle 3. Strip – Buy 1 Call, Buy 2 Puts (Same Strike, T) Greater profit from a large decline than a large increase (Strip) Page 10 of 11 Fin4328 (Moore) Trading Strategies with Options Summer 2006 4. Strap - Buy 2 Calls, Buy 1 Put (Same Strike, T) Greater Profit from a large increase than a large decline 5. Strangle – Buy Call with lower X1 , Buy Put with Higher X2 Similar to a Bottom Straddle (with a flat bottom) Page 11 of 11
