Quote from annaland:
I understand the bear spread, you buy a put(call) with a higher strike price and sell another put(call) with a lower strike. This limits your upside profit and risk, but I donât understand how time is working for you?
BEAR Call Spread is a bit different from a Bear Spread.
BCS is a credit spread, while a Bear Spread is a debit spread.
In a credit spread, you RECEIVE money for entering the trade, instead of paying.
Let me illustrate.
In this BEAR Call Spread, we are doing the following:
sell one AAPL Apr07 Call with 95 strike
buy one AAPL Apr07 Call with 100 strike
(you can do multiple contracts. I put one in there to indicate this is an equal-leg spread.)
This trade is entered as a spread order. For executing this order, we receive a credit of $1.40.
We don't really care what price the options are trading individually, the broker looks after that, as long as the offset results in a credit of $1.40.
For illustration purpose, let's say the 95c was sold at $2, and the 100c was bought at $0.60, thus giving us a credit of $1.40.
For illustration purpose, let's say we enter this trade when AAPL was trading at $94.
AAPL can fluctuates at any price it wants between now and expiration.
AAPL can trade higher.
AAPL can trade lower.
But for whatever miraculous reason, AAPL finishes trading on expiration date (April 21, 2007) at exactly $94, the same price when we entered the trade.
What happens to the BEAR Call Spread we have?
1. the 95c will become worthless because the strike is above the stock price.
2. the 100c will become worthless because the strike is above the stock price.
What happens to the credit we received?
ans: It is all ours to keep.
What is this Theta thing?
The 95/100 options are OTM options. The credit we received are ALL time values. There is NO intrinsic value in the cost of the option.
Time value decays with the passage of time... until it worths ZERO at expiration.
There is only ONE guaranteed profit in trading, that is -- Time Value DECAYS EVERYDAY.
Thus, when the time value decays, we say time is working for us.
