when buying options there's a few things to consider and one of the most important factors is the Delta

What Is Delta?

Delta is the ratio that compares the change in the price of an asset, to the corresponding change in the price of its stock. For example, if a stock option has a delta value of 0.65, this means that if the underlying stock increases in price by $1 per share, the option on it will rise by $0.65 per share, all else being equal. Delta values can be positive or negative depending on the type of option. For example, the delta for a call option always ranges from 0 to 1 because as the underlying asset increases in price, call options increase in price. put option  deltas always range from -1 to 0 because as the underlying security increases, the value of put options decrease

Delta values can be positive or negative depending on the type of option.
