First up is Google (GOOG - Get Report), a stock that can't escape comparisons with Facebook. The social network is set to unseat Google's spot as the biggest internet IPO in history when its shares finally go public tonight. But Google has some worthwhile action going on in its stock chart. That's why traders should be paying attention to the symmetrical triangle forming in shares.
A symmetrical triangle is a pattern that's formed by two trend lines that are converging at the same rate. Typically, it's a continuation pattern, which means that it's a sideways move that's effectively a pause while traders absorb a previous move in a stock before continuing in the same direction. Since Google's last big directional push was up from its October lows, a continuation would mean more upside for GOOG. The buy signal comes when shares break out above that upper trend line.
