Rising
Wedge (Reversal pattern) |
The rising wedge is a bearish pattern that begins wide at the bottom and
contracts as prices move higher and the trading range narrows. In contrast to
symmetrical triangles, which have no definitive slope and no bullish or bearish
bias, rising wedges definitely slope up and have a bearish bias.
Even though this article will focus on the rising wedge as a reversal
pattern, the pattern can also fit into the continuation category. As a
continuation pattern, the rising wedge will still slope up, but the slope will
be against the prevailing downtrend. As a reversal pattern, the rising wedge
will slope up and with the prevailing trend. Regardless of the type (reversal or
continuation), rising wedges are bearish.
- Prior Trend: In order to qualify as a reversal pattern, there must
be a prior trend to reverse. The rising wedge usually forms over a 3-6 month
period and can mark an intermediate or long-term trend reversal. Sometimes the
current trend is totally contained within the rising wedge; other times the
pattern will form after an extended advance.
- Upper resistance line: It takes at least two reaction highs to form
the upper resistance line, ideally three. Each reaction high should be higher
than the previous high.
- Lower support line: At least two reaction lows are required to form
the lower support line. Each reaction low should be higher than the previous
low.
- Contraction: The upper resistance line and lower support line
converge as the pattern matures. The advances from the reaction lows (lower
support line) become shorter and shorter, which makes the rallies
unconvincing. This creates an upper resistance line that fails to keep pace
with the slope of the lower support line and indicates a supply overhang as
prices increase.
- Support break: Bearish confirmation of the pattern does not come
until the support line is broken in a convincing fashion. It is sometimes
prudent to wait for a break of the previous reaction low. Once support is
broken, there can sometimes be a reaction rally to test the newfound
resistance level.
- Volume: Ideally, volume will decline as prices rise and the wedge
evolves. An expansion of volume on the support line break can taken as bearish
confirmation.
The rising wedge can be one of the most difficult chart patterns to
accurately recognize and trade. While it is a consolidation formation, the loss
of upside momentum on each successive high gives the pattern its bearish bias.
However, the series of higher highs and higher lows keeps the trend inherently
bullish. The final break of support indicates that the forces of supply have
finally won out and lower prices are likely. There are no measuring techniques
to estimate the decline -- other aspects of technical analysis should be
employed to forecast price targets.
ANN provides a good example of the rising wedge as a reversal pattern that
forms in the face of weakening momentum and money flow.
- Prior Trend: From a low around 10 in Oct-98, ANN surpassed 23 in
less than 7 months. The final leg up was a sharp advance from below 15 in Feb
to 23.5 in mid-April.
- Upper resistance line: The upper resistance line formed with three
successively higher peaks.
- Lower support line: The lower support line formed with three
successive higher lows.
- Contraction: The upper resistance line and lower support line
converged as the pattern matured. A visual assessment confirms that the slope
of the lower support line is steeper than that of the upper resistance line.
Less slope in the upper resistance line indicates that momentum is waning as
the stock makes new highs.
- Support break: The stock hugged the support line for over a week
before finally breaking with a sharp decline. The previous reaction low was
broken a few days later with long black candlestick (red arrow).
- Volume: Chaikin Money Flow turned negative in late April and was
well below -10% when the support line was broken. There was an expansion of
volume when the previous reaction low was broken.
- Support from the April reaction low around 20 turned into resistance and
the stock tested this level in early July before declining further.
