This would be the last time that Yahoo tested the lower band as it marched upward toward the upper band. As we all know, every strategy has its drawbacks and this one is definitely no exception. In the following examples, we'll demonstrate the limitations of this strategy and what can happen when things do not work out as planned. When the strategy is incorrect, the bands are still broken and you'll find that the price continues its decline as it rides the band downward.

Unfortunately, the price does not rebound as quickly, which can result in significant losses. In the long run, the strategy is often correct, but most traders will not be able to withstand the declines that can occur before the correction. The selling pressure was clearly in oversold territory. The strategy called for a buy on the stock the next trading day.

Like the previous examples, the next trading day was a down day; this one was a bit unusual in that the selling pressure caused the stock to go down heavily. The selling continued well past the day the stock was purchased and the stock continued to close below the lower band for the next four trading days.

Finally, on March 5, the selling pressure was over and the stock turned around and headed back toward the middle band. Unfortunately, by this time the damage was done.

The strategy calls for buying Apple shares on December The next day, the stock made a move to the downside. This is case where the selling continued in the face of clear oversold territory.

During the selloff there was no way to know when it would end. There are times, however, when the strategy is correct, but the selling pressure continues. During these conditions, there is no way of knowing when the selling pressure will end. Therefore, a protection needs to be in place once the decision to buy has been made.

The strategy correctly got us into that trade. Both Apple and IBM were different because they did not break the lower band and rebound. Instead, they succumbed to further selling pressure and rode the lower band down. This can often be very costly. In the end, both Apple and IBM did turn around and this proved that the strategy is correct. The best strategy to protect us from a trade that will continue to ride the band lower is to use stop-loss orders.

In researching these trades, it has become clear that a five-point stop would have gotten you out of the bad trades but would have still not gotten you out of the ones that worked. In every scenario, the break of the lower band was in oversold territory. The timing of the trades seems to be the biggest issue. This selling pressure is usually corrected quickly. When this pressure is not corrected, the stocks continued to make new lows and continue into oversold territory. To effectively use this strategy, a good exit strategy is in order.
