EXHIBIT 2.1 Call value compared with stock price.
|
||
Definition 3 : In terms of absolute value (meaning that plus and minus
|
||
signs are ignored), the delta of an option is between 1.00 and 0. Its price can
|
||
change in tandem with the stock, as with a 1.00 delta; or it cannot change at
|
||
all as the stock moves, as with a 0 delta; or anything in between. By
|
||
definition, stock has a 1.00 delta—it is the underlying security. A $1 rise in
|
||
the stock yields a $100 profit on a round lot of 100 shares. A call with a
|
||
0.60 delta rises by $0.60 with a $1 increase in the stock. The owner of a call
|
||
representing rights on 100 shares earns $60 for a $1 increase in the
|
||
underlying. It’s as if the call owner in this example is long 60 shares of the
|
||
underlying stock. Delta is the option’s equivalent of a position in the
|
||
underlying shares .
|
||
A trader who buys five 0.43-delta calls has a position that is effectively
|
||
long 215 shares—that’s 5 contracts × 0.43 deltas × 100 shares. In option
|
||
lingo, the trader is long 215 deltas. Likewise, if the trader were short five
|
||
0.43-delta calls, the trader would be short 215 deltas.
|
||
The same principles apply to puts. Being long 10 0.59-delta puts makes
|
||
the trader short a total of 590 deltas, a position that profits or loses like
|
||
being short 590 shares of the underlying stock. Conversely, if the trader
|
||
were short 10 0.59-delta puts, the trader would theoretically make $590 if
|
||
the stock were to rise $1 and lose $590 if the stock fell by $1—just like
|
||
being long 590 shares.
|
||
Definition 4 : The final definition of delta is considered the trader’s
|
||
definition. It’s mathematically imprecise but is used nonetheless as a
|
||
general rule of thumb by option traders. A trader would say the delta is a
|
||
statistical approximation of the likelihood of the option expiring in-the- |
