Biogen Returns To The Breakout

05/24/07 10:36:20 AM
by Arthur Hill

After breaking resistance with a gap and a surge in April, Biogen Idec returned to the scene of the crime. This level should offer support.

Security:   BIIB
Position:   Accumulate

Biogen Idec (BIIB) broke resistance in late April with a big gap and strong surge above 48. The move broke above the January trendline and the February high. The gap and long white candlestick show that there was clearly some power behind the breakout (green oval) (Figure 1).

Broken resistance turns into support, and BIIB returned to the breakout over the last few weeks. This is not uncommon, and a strong stock should hold support from its breakout. There is also support in this area from the 50-day moving average, which acted as resistance in mid-April. Failure to hold above 45.5 would show weakness and likely lead to a test of the March low.

The decline over the last few weeks formed a falling flag, and I am watching resistance at 47.5 for a breakout. Flags represent mild corrections, and bullish flags slope down. A move above 47.5 would signal a continuation of the April surge and target a move to around 53, which is resistance from the December high.

I am also looking for the moving average convergence/divergence (MACD) to cross above its signal line for confirmation. The MACD histogram (red) shows the difference between the MACD and its signal line. The histogram is positive when the MACD is above its signal line and negative when the MACD is below its signal line. The MACD is firming just above the zero line, and a move above the signal line would signal an upturn in momentum.
