To me I will keep it simple for you...in options pricing there are only a few variables...the price is based on the length of time to expiration, the beta of the stock AND the beta of the market and then the distance from the stock price... I understand all that stuff posted above but you really do not need to input ten pages of data to black scholes to get your answer, its much more simple than doing that. So go back to the stock and that option chain and look at the current bid/ask, then if you really want to get fancy get the option symbol and enter it and some brokers will show a chart of an options symbol and you can see how the contract has traded over time and with only one month left to expiry per your post and it being so far out, that is not a current bid/ask.
Huh? It really is NOT that simple at all.
I think his question was about what he could profit if the stock doubled in price in a month?
In all my years of this I have not heard anyone say they can look at simply the current bid/ask, past chart and determine a future stock option price? Or maybe I misunderstood his question. Or maybe I misunderstood the question you were answering.
Current bid/ask is .43/.44
So, yes that was quite likely what the current ask price was if he saw it at some point yesterday. Because it opened at .1 and went past .23 at some point to a close of .75.
It is not 10 pages of data you need to input. And, as I explained they have online calculators that do this for you already. Basically 7 variables. As the link explains:
There are seven factors in the model: stock price, strike price, type of option, time to expiration, interest rates, dividends and future volatility. Of the seven factors, only one is not known with any certainty: future volatility. This is the main area where the model can skew the results.
Out of the seven factors volatility is the only one that is estimated. Out of the seven factors, the most important are stock price, strike price, type of option, time to expiration and volatility. Interest rates and dividends have a very minuscule effect on an option's value.
Two of those (interest rates and dividends) do not matter that much. The key things to understand are volatility, and intrinsic value and extrinsic value.
