As stocks recovered from the October plunge, the biotechnology sector quickly jumped back into its leadership role. The iShares Nasdaq biotechnology exchange-traded fund (ticker: IBB) moved to an all-time high with a rather clean technical pattern breakout. With solid absolute and relative performance, it would seem that biotech is the place to be whether the market continues to rally or lapses back into weakness.

This provides a quandary for investors. The short-term looks rather hot but after leading the market for the entire duration of the 2009-2014 bull run, the sector looks a bit scary.

In the short-term, buying the breakout looks to be a good strategy, especially when the sector ETF negated a technical breakdown just two weeks ago (see Chart 1). In technical analysis, failed breakdowns are usually bullish signals and so far that seems to be the case here.

The NYSE Arca Biotechnology Index (known as the BTK index), which has a much longer data history, shows an even stronger short-term pattern than the Nasdaq biotech ETF. However, in the long-term we can see something a bit more sinister. The rally since 2011 has been accelerating leaving a dangerous pattern for bulls and bears alike (see Chart 2).

A rising trend is a good thing and in the market, as in physics, a body in motion tends to stay in motion. An entire subset of trading is predicated on following the trend and we all know the mantra "the trend is your friend."

But when a trend accelerates, its slope on the charts gets ever steeper -- and unsustainable. Momentum takes over as investors jump in at any price so as not to be left behind. Clearly, the acceleration in biotech today is not the same as it was in weeks leading up to the final blow-off at the end of the bubble in 1999-2000 but it is still of concern.

The problem is that these moves are nearly impossible to time. The trend can last for weeks or months to come or it can turn on a dime and lead to a very rapid descent. Both scenarios are just as likely when we get a frothy market.

Again, biotech does not look to be in a true bubble but its trend is indeed accelerating and it has been rallying for several years at a rapid pace. Since beginning its steep rally in November 2011, the BTK index has more than tripled in value -- a 214% gain. Compare that to the Standard & Poor's 500 and its 69% gain over that same span. Plus, we can draw several progressively steeper trendlines in the chart that should raise some concern.

With this in mind, let's take a look a representative individual stock that still looks good on the surface but has a problem or two behind the scenes.

Gilead Sciences ( GILD), which works in such areas and AIDS and hepatitis research, set intraday and closing highs Friday (see Chart 3). Considering that it happened after saving what appeared to be a devastating trendline breakdown, investors should be quite happy.

But on-balance volume, which keeps a running tab on volume traded on up-days minus down-days, is still in decline since August. This tells us that there was not as much power behind the comeback rally this month as we would expect. We can infer that it was a lack of sellers rather than a preponderance of buyers that did the work and that is not a healthy way to rally.

Is that a reason to sell the stock? Not really. But it does warn that something is not as rosy as the bulls would like. Jumping in with both feet is probably not the right move, especially at this stage in an old bull market.

Gilead announces earnings Tuesday after the close of regular trading (See The Striking Price, " Gilead Stock Should Move Big on Earnings Report," Oct. 27).

Biotech presents a problem in that the trend is still up but the warning signs that it is getting old are starting to build. While pockets within are getting news-related boosts as Ebola stays in the news, overall to me it looks to be time to cut down on new money being put to work here. Some money, yes, but not the same heavy flow as before.
