Breakouts of long bases on strong volume are frequent harbingers of continued price appreciation. Another harbinger, after the initial up-leg, is a low-volume, orderly pullback towards support. Understanding these winning chart patterns will help you in making successful stock picks.

An analysis of the Converted Organics chart illustrates this stock picking strategy. As the daily chart indicates, COIN in October 2007 broke out of a base pattern that extended back since its IPO in late February. Some traders who missed entering early may have given up on the stock when it rose 50% from around 2 1/2 to 3 3/4, but a closer look at the chart shows why it had more room to move.

COIN's pullbacks were orderly, coming on lower volume and holding near its moving averages, a key sign of more upside to come. Not once did its pullback break beneath the 40-day moving average, and most pullbacks hugged the 21-day moving average.

The pattern was breakout (mid-October), flag, breakout (early November), flag, breakout (late December), flag, and then breakout in mid-January, where it closed on January 15 at 12.58, more than 5 times its pre-October breakout price. Volume on each pullback was a small fraction of the level of the breakout, and a shallow decline just grazing the moving averages suggested a continuation of the uptrend.

In making stock picks, as a stock in a rising pattern pulls back look for several factors that portend the continuation of the pattern.

1. First, look for very low volume on the pullback -- between 10% and 25% of the average volume of the last 90 days. Second, watch for the decline to flatten near the 21- or 40-day moving average on the hourly charts in a quiet, narrow flag-type formation.

2. When the breakout comes, buy on the initial thrust out of this flag pattern. This means a sudden dramatic change in price accompanied by heavy volume. The price doesn't necessarily have to rise above the top of the flagpole (i.e., the previous rally high prior to the consolidation), but only needs to be a price bar that is at least several times the size of the previous several bars on the chart.

3. Wait to add to the position until the stock takes out the top of the flagpole, which is key short-term resistance. This will protect against a head fake, which is a move that starts out dramatically but quickly fizzles price- and volume-wise after just a bar or two and has no follow-through and, in particular, does not make it through the top of the flagpole.

4. Set a stop below the bottom of the lowest level reached during formation of the consolidation or flag pattern out of which it has broken. When COIN, for example, in its November upmove exceeded the top of its October flagpole around 3.75, that was one signal to get in or add to the position. Another signal came in the second week of January at around the 8 level, when we first made this stock pick for our subscribers.

We saw COIN having consolidated and tested its 8.70 triple-top resistance over the previous 3-4 sessions, and noted that if it broke through that level it could initially head to 10 1/2-11, and then beyond that to our next target of 12 1/2-13, where it last resided, as mentioned, on January 15.

The COIN example illustrates the potential that chart patterns like high-volume breakouts from long bases and low-volume flags can have in predicting price appreciation and helping you make successful stock picks.
