ANATOMY OF A TRADE
Riding The Roller-Coaster
The Bounce Trade
by Thomas Bulkowski
A double bounce following a long decline spells a trading opportunity.
Find out why.
I'm not sure exactly how I happened upon
this chart pattern. I noticed that after a long, perhaps straight-line
decline, stocks often bounce -- not once but twice. Figure 1 displays an
example of this. In the fall of 1997, National Semiconductor (NSM) peaked
at $42.875, along with other stocks in the semiconductor industry. A year
later, it reached a low of just $7.4375, an astounding decline of 83%.
As can be expected, but rarely anticipated correctly, the stock bounced.
Two months later, it climbed to a high of $17.625, more than double the
nadir.
Figure 1: NATIONAL SEMICONDUCTOR CORP (NSM). Two bounces follow
a long decline on the weekly scale. This is not a double bottom, because
the price difference between the bottoms is almost 20%.
A retest of the low usually occurs, and that's what happened next. The
stock declined to a low of $8.625 in early April 1999, retracing most of
its gains. Although the twin lows appear to be a double bottom, strictly
speaking, they're not. For a double bottom, the two lows should be within
4% of each other. Here, the price difference is almost 20%, though the
discrepancy is more visible on the daily scale.
So why not trade the twin lows as if they formed a double bottom? In
a word: money. By the time prices rise to the confirmation point,
you've given up a lot of it. Look at Figure 2, a chart of Timberland Co.
(TBL), and you'll see what I mean. The second low occurs at a price of
$33, and the confirmation point is the highest high between the two lows,
or $51.25 in this case. You'd have to wait for prices to climb more than
18 points, or 55%, before the double bottom confirms (meaning it's a true
double bottom).
