Are Leadership Groups Breaking Down?

 | Aug 07, 2015 01:09AM ET

Even the most skeptical of investors would have to say that biotech and Apple (NASDAQ:AAPL) have been two leadership “groups” for quite some time, years in fact.

While some might not consider an AAPL a “group”, with a 4% market cap weight, a 6% earnings weight, and a 15% weight in the QQQ, how can anyone not consider AAPL important to the stock market ?

The recent breakdown in the stock below the November ’14 $119.75 high was noted for its absence of any kind of fundamental catalyst, even earnings and revenue revisions are still positive. AAPL filled an outstanding gap yesterday near $112.50, so the correction might be over already, but if $112.50 does not hold, then the September, 2012, split-adjusted high of $100.75 comes into play from a technical perspective.

Leadership stocks never typically break down with fundamental news: look at large-cap pharma in 1997, and then technology in March of 2000.

It may be much ado about nothing, but AAPL has my attention.

Speaking of healthcare, check the attached chart of BIB (NASDAQ:BIB) or the Ultra Nasdaq Biotechnology Index. Down 8% today, down 4% on the week, that looks like a nasty reversal. Even staid, quiet names like Amgen (NASDAQ:AMGN) fell $6 or 3.8% today. Biogen's (NASDAQ:BIIB) collapse is well known now, down from a high of $500 in mid-March ’15 to $300 as of Friday, July 24th, 2015, and although the stock has bounced a little, BIIB looks to be rolling over again.
