BOLLINGER BANDS


Tollgrade Gaps Up

A gap up and MACD crossover point to higher prices for Tollgrade Communications.

Security:   TLGD
Position:   Accumulate

Periods of reduced volatility are often followed by periods of increased volatility, and we can often anticipate a breakout by looking for periods of reduced volatility. Figure 1, the daily chart, shows Tollgrade (TLGD) with Bollinger Bands overlaid on the price plot. These reflect volatility, and the narrowing of the bands shows reduced volatility. The bands narrowed in January, and this preceded a breakout in early February. The current narrowing of the bands points to an impending volatility expansion, and the stock surged to the upper band with a gap up. This signals the beginning of a volatility expansion, and I am expecting a move.

The gap up is bullish, and a bullish crossover in the moving average convergence/divergence (MACD) confirms this. The stock consolidated for two months and the MACD returned to the zero line in late March. The area just above the zero line also offered support in late January. The decline in the MACD represents a correction of sorts, and the recent upturn signals that the correction is over. The gap is a signal that the consolidation on the price chart has run its course. I would consider the gap bullish as long as it holds and a move back below support at 11.50 would be bearish.

I will turn to the weekly chart for an upside target (Figure 2). TLGD surged from August 2006 to January 2007 and then consolidated the last two months. The pattern looks like a flat flag and a break above the consolidation highs would signal a continuation higher. I find the gap on Figure 1 bullish, but Figure 2 still shows some resistance around 13. A break above 13 would clear the air and target a move to the next resistance zone around 16. It is also worth pointing out that upside volume has been above average in 2007, and this further reinforces strength in the advance.
