Conclusion Trend lines can offer great insight, but if used improperly, they can also produce false signals. Other items - such as horizontal support and resistance levels or peak-and-trough analysis - should be employed to validate trend line breaks. While trend lines have become a very popular aspect of technical analysis, they are merely one tool for establishing, analyzing, and confirming a trend. Trend lines should not be the final arbiter, but should serve merely as a warning that a change in trend may be imminent. By using trend line breaks for warnings, investors and traders can pay closer attention to other confirming signals for a potential change in trend. The uptrend line for VeriSign (VRSN) was touched 4 times, and seemed to be a valid support level. Even though the trend line was broken in Jan-00, the previous reaction low held, and did not confirm the trend line break. In addition, the stock recorded a new higher high prior to the trend line break.
