Long call: Breakeven = strike + premium; max loss = premium; max gain = unlimited
Example: Buy 1 ABC Jan 40 call at $2.50: breakeven $42.50; max loss $250.
Long put: Breakeven = strike - premium; max gain = strike - premium (x100)
Example: Buy 1 ABC 40 put at $3: breakeven $37; max gain $3,700 if ABC goes to 0; max loss $300.
Covered call: Breakeven = stock cost - premium; max gain = strike - cost + premium
Example: Own 100 at $50, sell a 55 call for $2: breakeven $48; max gain (55 - 50 + 2) x 100 = $700; max loss $4,800.
Long margin account: Equity = LMV - debit; Reg T = 50% of purchase
Example: Buy $20,000 of stock on margin: deposit $10,000, debit $10,000. At LMV $18,000, equity = 18,000 - 10,000 = $8,000.
Long maintenance call price: Debit / 0.75
Example: With a $10,000 debit, a maintenance call hits when LMV falls below 10,000 / 0.75 = $13,333 (25% minimum).
Taxable-equivalent yield: Muni yield / (1 - tax bracket)
Example: A 3.3% muni for a 32% bracket investor: 3.3 / 0.68 = 4.85%.
Conversion parity: Par / conversion price = conversion ratio; parity = bond price / ratio
Example: $1,000 bond convertible at $25 = 40 shares. Bond at $1,080: parity stock price = 1,080 / 40 = $27.
Current yield: Annual interest / market price
Example: 6% coupon at 104 ($1,040): 60 / 1,040 = 5.77%.
