Formulas and concepts

Current yield: Annual interest / market price

Example: A 5% bond ($50/year) priced at $1,000 x 0.92 = $920: current yield = 50 / 920 = 5.43%. Price below par, so current yield is above the coupon.

Bond price vs. yield: Price and yield move in opposite directions

Example: Rates rise, existing bond prices fall. A discount bond has YTM > current yield > coupon; a premium bond is the reverse.

Mutual fund sales charge %: (POP - NAV) / POP

Example: NAV $19.00, POP $20.00: sales charge = 1.00 / 20.00 = 5% (always divide by the offering price).

Stock split: New shares = old x ratio; new price = old / ratio

Example: 100 shares at $60 with a 3-for-2 split: 150 shares at $40. Total value unchanged at $6,000.

Long call breakeven: Strike + premium

Example: Buy 1 XYZ 50 call for $3: breakeven $53; max loss $300 (premium x 100 shares).
