6      How Delta is expected to change given a $1 move in the underlying is called
7      <b>Gamma</b>. An investor can see how the Delta will affect an option's price given a $1 move in the underlying,
8      but to see how the Delta on that option <b>might change</b> given the same $1.00 move, we refer to Gamma.&nbsp;

12      Looking at a hypothetical example, OICX is trading at $50 per share. The OICX Jan $50 call is trading for $2, has
13      a Delta of .50 and a Gamma of .06. Should OICX go up to $51, an investor can estimate that the $50 strike call
14      will now be worth around $2.50. The new Delta of this $50 strike call at an OICX price of $51 should be around
15      0.56 (simply adding the Gamma of .06 to the old Delta of .50).

22    <ul>
23      <li>
24        A call has a Delta of .54 and Gamma of .0400 (.04)
25        <ul class="mt-2">
26          <li>Stock goes up $1</li>
27          <li>Delta will become more positive by the Gamma amount</li>
28          <li>New Delta value: .58</li>
29        </ul>
30      </li>
31      <li>
32        Another call has a Delta of .75 and Gamma of .0340 (.03)
33        <ul class="mt-2">
34          <li>Stock is down $1</li>
35          <li>Delta will become less positive by Gamma amount</li>
36          <li>New approximate Delta value: .72</li>

42      Long options, either calls or puts, always yield positive Gamma. Short calls and short puts will have negative
43      Gamma. Underlying stock positions will not have Gamma because their Delta is always 1.00 (long) or -1.00 (short)
44      and will not change. Positive Gamma means that the Delta of long calls will become more positive and move toward
45      +1.00 when the stock price rises, and less positive and move toward 0 when the stock price falls. Long Gamma also
46      means that the Delta of a long put will become more negative and move toward –1.00 if the stock price falls, and
47      less negative and move toward 0 when the stock price rises. For a short call with negative Gamma, the Delta will
48      become more negative as the stock rises, and less negative as it drops.
49    </p>
50
51    <p>
52      Gamma is higher for options that are at-the-money and closer to expiration. A front-month, at-the-money option
53      will have more Gamma than a LEAPS® option with the same strike because the Delta of the near term options move
54      toward either 0 or 1.00 is imminent. With higher Gamma, investors can see more dramatic shifts in Delta as the
55      underlying moves, especially with the underlying around the strike at expiration.

69      Gamma is lower in the longer-dated <b>LEAPS</b>® as more strikes remain possibilities for being in-the-money at
70      expiration because of the amount of time remaining. An at-the-money-option’s Delta is typically the most sensitive
71      to moves in the underlying (hence higher Gamma). With the stock right at a strike at expiration, an option’s Gamma
72      will be at its highest as the Delta will be potentially moving from 1.00 toward 0 or vice versa as the underlying
73      crosses a strike. In these cases, the Gamma can be extremely high as the Delta changes rapidly with the underlying
74      at the strike and expiration approaching.
75    </p>
76
77    <p>
78      Deep-in-the-money or far-out-of-the-money options have lower Gamma than at- the-money options. The
79      deep-in-the-money options already have a high positive or negative Delta. If the options become deeper
80      in-the-money, the Delta will move toward 1.00 (or -1.00 for puts) and the Gamma will decrease because the Delta
81      cannot move past 1.00. If the stock were to move toward the strike of the deep-in-the-money option, the Gamma will
82      increase and the Delta moves lower approximately by the amount of the current Gamma.

86      For example, let’s say OICX is trading at $30. A $25 strike call is trading for $5.80 and has a Delta around .85
87      and a Gamma of .03. If OICX were to drop to $29, the investor might expect the option premium to drop to $4.95 (as
88      projected by Delta). With stock at $29, the Delta of the option will be decreasing by approximately the amount of
89      the Gamma, so the new Delta at an OICX price of $29 might be .82 (here we subtract the Gamma from the old Delta as
90      the stock price declined by $1). With the stock moving down toward the long strike, Gamma increases and impacts
91      Delta. Should the stock decline to $25, we’d estimate Delta to be around .50. If the Gamma stayed around .03, the
92      option would still have a .70 Delta with the stock at $25. However, since Gamma typically increases as options
93      become closer to at-the-money, the new Gamma of this contract may be around .09.

97      Gamma is highest when the Delta is in the .40-.60 range, or typically when an option is at-the-money.
98      Deeper-in-the-money or farther-out-of-the-money options have lower Gamma as their Deltas will not change as
99      quickly with movement in the underlying. As Deltas approach 0 or 1.00 (or 0 or -1.00 for puts), Gamma is usually
100      at its lowest point.
101    </p>
102
103    <p>
104      Implied volatility changes will also have an effect on Gamma. As implied volatility decreases, Gamma of
105      at-the-money calls and puts increases. When implied volatility goes higher, the Gamma of both in-the-money and
106      out-of-the-money calls and puts will be decreasing. This occurs because low implied volatility options will have a
107      more dramatic change in Delta when the underlying moves. A high implied volatility underlying product will see
108      less of a Delta change with movement as the possibility of more movement is foreseen.
