Gerry's recommendations have proved to be very reliable and profitable.
Nevertheless, the supplementary use of technical analysis to assist in timing
entries and exits can enhance these profits. PTD is an excellent example of
this.
Anyone buying PTD on Gerry's recommendation ($2.30, 29/9/01) would have
doubled their money in just over 4 months, only to give all their gains back to
the market over the next 3 months. The use of some fairly elementary TA would
would have obviated this.
The attached chart demonstrates use of the Directional Movement Indicator, a
deservedly popular trend indicator. As with all trend indicators, DMI gives
unreliable signals if a stock is not trending. This is determined by the
ADX/ADXR elements of the Directional Movement system, which constitute the
"trend ribbon" beneath the DMI. Any +DI/-DI crossover signals are only
significant if the ADXR is greater than 25, and the ADX is greater than either
+DI or -DI. If these conditions are met, the trend ribbon shows a "Trade Zone".
If these conditions are not met, the trend ribbon shows a "No Trade Zone" and
any crossover signals are ignored.
The chart has not been optimised or curve-fitted in any way whatsoever. All
DMI indicators utilised (+DI, -DI, ADX, ADXR) use the MetaStock default value
of 14 days.
I have also plotted a 35 day exponential moving average. Note the
exceptionally close agreement between the signals generated by these two very
different trend indicators.
Phaedrus.
