Time Value Again
A "call" option is the right to buy a stock at a set price known as the "strike price" or "exercise price." If the stock is worth $3 more than that strike/exercise price, the call option is worth that $3 difference, always. That's the intrinsic value of being able to save $3 when buying that stock. But, the option would be worth more than just that $3, as long as there is still some time left. If there is still a month to go, an ABC Aug 50 call might be trading for $4 a share, when ABC common stock is only trading for $53. The intrinsic value is $3, but there is still time for ABC to keep rising. If you want to buy this call option, you pay $4 a share, which is $3 of intrinsic value and $1 of time value. If the stock stops moving at $53, that time value will begin to evaporate quickly, as time runs out on the option. If you buy this option for $4 today, you can only win if the stock rises, and rises fast enough to outweigh the negative effects of time.
Let's work with the concept of time value in a rather annoying practice question:
Which option below has the most time value if ABC currently trades at $51 a share?
A. ABC Aug 50 call @$1.50
B. ABC Oct 50 call @2.50
C. ABC Oct 50 put @2.00
D. ABC Oct 55 put @4.25
EXPLANATION: step one, find the intrinsic value in each option and subtract that out of the premium. An Aug 50 call @1.50 has $1 of intrinsic value, 50 cents of time value. An Oct 50 call (which HAS to have more time value on it than the Aug 50) also has $1 of intrinsic value and, therefore, $1.50 of time value. Choice A is eliminated. An Oct 50 put has ZERO intrinsic value, so the time value is $2.00. Choice B is eliminated. An Oct 55 put has $4 of intrinsic value, so only 25 cents per share of time value. D is eliminated. The Answer is . . .

Time Value
Remember, not all Series 7 questions concerning options involve calculations or even numbers. Many of the tougher options questions look like the one below:
Which of the following represents an accurate statement about put options on ABC common stock?
A. If ABC common stock drops from $45 to $40, an ABC Aug 40 put goes in the money
B. If ABC common stock drops from $45 to $40, the premium on an ABC Aug 40 put would likely increase
C. If ABC common stock drops from $45 to $40, an ABC Aug 40 put goes out of the money
D. If ABC common stock rises from $35 to $40, the ABC Aug 40 put premiums should increase
EXPLANATION: as always, try to eliminate some answer choices. Choice A says that an ABC Aug 40 put would be in the money with the stock at $40. That makes no sense, so eliminate it. Choice C says that an ABC Aug 40 put would be out-of-the-money with the stock at $40, but, actually, it would be at-the-money. Choice D says that put premiums increase when the stock price rises, but that's backwards. Strike prices are fixed--the puts only become more valuable as the underlying stock drops, making the right to sell it more valuable. Eliminate Choice D, and you're done. Why is Choice B accurate? Remember that even though the ABC Aug 40 put would not go in the money if the stock dropped from $45 to $40, the "time value" would increase, the speculative component of the premium. With the stock at $45, the right to sell it at $40 is not worth much, but if the stock then drops to $40, the market would assume it could easily keep dropping, and any little drop makes the put go in-the-money. The premium would reflect the 50-50 chance that the option will go in-the-money, and, of course, the premium would be 100% time value. So, a seller might like to write an at-the-money option, and then if the stock simply stops moving, that time value will evaporate, letting the seller keep the whole premium without lifting a finger as the option expires.
