The Problem
Since the beginning of 1997, the U.S.-sold Japan Fund has experienced substantial cash inflows and outflows from investors, and portfolio manager David Smith has voiced his concern recently about the volatility. He also noted that extremely large shareholder orders seem to coincide more and more with news affecting Japan, and cash flow management is taking up a large percentage of his time that might otherwise be spent selecting securities.
Smith suspects some shareholders are trying to increase their profits by “timing” the market—quickly moving their money from one fund to another within the complex. Furthermore, he speculates that these investors might be attempting to profit from the methodology that the fund complex uses to compute the daily NAV of the fund by trading on stock price information that may become available between the time when the Japanese markets close and the time the fund values its holdings.

What if a stock has run out of steam and we’re anticipating a period of consolidation or lower volatility for a period of time? What if we have identified a range-bound stock and we want to take advantage of this price pattern behavior? We can achieve this by trading low-risk, high-reward options strategies! The two strategies we’ll discuss in this chapter are the Butterfly and the Condor, both of which produce profits provided the price remains within a certain price range, determined by the Exercise prices we select.
Butterflies
The Butterfly involves the following steps (you can use all calls or all puts with the Butterfly—you cannot mix the two):
Butterfly with Calls
Step 1 Buy 1 lower strike (ITM) call
Step 2 Sell 2 middle strike ATM calls
Step 3 Buy 1 higher strike (OTM) call
There are two key points here:
- The ratio between buying the ITM call, selling the ATM calls, and buying the OTM call is 1:2:1.
- The distance between the three adjacent strikes must be equal, with the middle strike being ATM or as close to ATM as possible.

Delta Delta peaks in between the two strike prices (i.e. near the money)—notice the difference
between the one-month Delta profile and the one-week delta profile. This shows us that small movements in the underlying stock price at these levels will have a more dramatic impact on the value of the Bull Put position. Delta becomes much more sensitive as time decays. This means that the Bull Put risk profile itself becomes much more sensitive as time decays. This is because Time Value is depleting to negligible levels, and so the stock movement is being followed almost exclusively by Intrinsic Value at these levels. Notice that as the stock price veers away from the money (on both sides), Delta is hardly sensitive at all and that the most sensitive Delta action is occurring close to the two strike prices.
Gamma The acceleration and deceleration of Delta is reflected in the Gamma values. As you would expect, Gamma peaks in positive territory where the stock is just below the lower strike price and troughs into negative territory where the stock is just above the higher strike price.
