Share Tweet Share Tweet. One important principle while valuing options is that at any time, the value of a call or a put cannot exceed certain limits — on the higher side as well as on the lower side. These maximum limits will have to be discussed for European and American options separately.

We first take up the upper and lower bounds of European calls. Upper bounds of European call values: In such a scenario, anybody can write the call and sell the stock on spot, and take home the difference of 5 per share. Dividend, when paid, decreases the value of shares to that extent. Hence on expiry, the stock will be valued at 45 50 — 5 in the spot market and logically, the call value cannot exceed 45 per share.

Option Price - Upper and Lower Bounds

This brings us to the first principle in option value — the upper bound value of an European call can never rise beyond the value of the underlying stock. When the dividend is known with certainty, the call values cannot rise beyond the spot value of the stock less present value of the dividend. What would be the lowest value for an European call?

It should be zero. It cannot fall below that, Right? For the call value to be at zero, the stock value should also fall to zero. If the stock call option bounds is above zero say 2 the minimum value of call should be the present value of Rs 2 strike price. One year European option call at strike price is available. In this case, the value of the call cannot fall below 2 — If it falls to say, Re 1 then —.

Minimum and Maximum Values for Options

As a next step, here also, we need to discus the effect of dividends. The dividend to be received a year later is estimated at Rs 5 per share. This brings us to the second principle in option value — the lower bound value of an European call can never fall below the difference between stock value and the present value of strike price.

When the dividend is known with certainty, the call values cannot fall below the spot value of the stock minus using hubpages to make money value of the dividend minus present value of the strike value.
