Stock Trading Using The DMI and Options

Saturday, June 19th, 2010

One investing strategy with options is to purchase a straddle. A straddle is when an investor buys both a call and a put for the same strike price and the same expiration date. The idea is that the investor does not have a comfort zone on which direction the market will go, either bull or bear. By purchasing a straddle he plays both ends. Whether or not the stock price goes up or down, he will still win. The problem becomes the cost to purchase the straddle. The investor does not want to make an incorrect decision and have the stock price remain stable. Then he would not win with either direction.

One solution to this problem is to do stock trading using the directional movement index (DMI) and options. The DMI is actually an index that tracks the movement of the stock price. It has a positive and a negative trend to the index. If the positive line is dominant then the stock price is going up. If the negative line is dominant then the stock price is going down. When they cross then the stock price trend is due for a shift. The average of the two is known as the average directional motion index (ADX).

The ADX will fluctuate between 0 and 100 but it usually does not go above 60. If the readings are below 20 then it is an indication of a weak trend. If it goes above 40 then it indicates a strong directional trend. What that means is if you find a stock with a reading above 40 then the trend is strong. This can be either an upward or downward trend. You cannot tell by the ADX which trend is dominant but you can tell by looking at both the positive and negative trend lines and the stock price.

What you are looking for with the purchase of a straddle is a weak, non-existent trend that is poised to move into a directional breakout. What you want to look for is the ADX being below 20 and watch for it to begin to move above 20. You may also watch the ADX for when the trend is beginning to end and then you will want to get out of your straddle. This would be of course when it is above 40 and starting to trend downward.

With the current volatile market conditions, the straddle option is a great way to make money with your investment strategy. Combining both option trading and the DMI is an awesome method to reduce your risk in making trades.

Three Technical Analytic Tools You Should Use

Monday, March 22nd, 2010

There are many different types of technical analytic indexes and information you may use in your analysis of a companies trends and momentums. Three of these that you should definitely use are the directional movement index (DMI), the relative strength index (RSI), and the Williams %R. The DMI is a trending type of index while the other two are momentum indexes

The DMI has a negative component to it. When it is trending upward, it indicates a continuation of the downward trend. When it is trending downward, it indicates an upward trend. The positive component of DMI is just the opposite of the negative component. Many investors who watch the directional movement index will watch for the point of when the positive and negative indicators cross each other as indicated in the chart below. The arrows point to two examples of when the indicators cross.
DMI

You can see from this example of the company Syntel, Inc (SYNT) that the trend indicators did work according to theory. In the case of the left arrow, when the negative indicator crossed above the positive indicator, the price of the stock went down and the opposite happened in the case of the right arrow when the price of the stock went upward.

Here is another example of the DMI indicator.

You can see the crossover points from where the arrows are pointing.

The relative strength index analyzes the magnitude of a stocks gains
and its losses over a period of time. The formula is:

100 minus 100/1+RS where RS is the average of the number of days of up closes
divided by the average of the number of down closes.

The actual calculation is as follows: Using 14 periods, sum the gains and divide by 14 to arrive at the first average RS. You would then multiply this average by 13 and add one more periods gain. You would then do the same for the losses for the same period. To really be accurate, you should start back 28 periods to arrive at the first average for the 28th – 15th periods and then take a rolling average for the next 14 periods. The more periods you use the more accurate it will be.

You will then divide the average gains RS by the average loss RS to arrive at the RSI for the period of time being evaluated. The closer the RSI is to 70, the closer it is to being overbought. Conversely,
the closer it is to zero, the closer it is to being oversold.

RSI Line

In looking at the above chart from Syntel, Inc. (SYNT) you can see that the middle indicator is the RSI line. It is fairly constant but has at the end turned upward to be close to the top of the graph.
This would indicate that the stock should turn downward. We would need to watch it to see if that actually happens. If you were to look back at the period where the arrow is pointing you would see that the stock price actually did go down right after that day indicating that the RSI was correct.

The Williams %R is the last trend line in the above graph. This indicator shows the close of the day in relation the high price and the low price of the past number of days. The formula is:
%R = highest high for the period of time being reviewed – most recent close divided by the highest high – lowest low for the same periods.

It is also used to indicate if a stock is supposedly overbought or over sold. As you can see from the above graph, it is a bit more volatile than the RSI graph. This graph is opposite of the RSI in that if the line is at the zero to -20 it is considered overbought and if it is from -80 -100 it is considered oversold. One thing to remember with the %R is that overbought may not mean that it is time to sell and over sold is not meant to mean that it is time to buy. A stock price can remain at a overbought situation for some time. The trader analyzing this indicator should wait until it is obvious that there has been a swing in the price. One idea would be to wait until the indicator crosses the mid point in the graph or to observe some other technical analytic indicators.

Have some fun with these three indicators. Play with them and see if they will work for you with your trading strategy. You might look back at some other stocks and see if what you thought would happen did in deed happen. Another thought would be to test your theory with a paper online game before actually investing your own money.
