Below are a few charts that you do NOT want to see if markets are to continue higher.

Biotech ETF, IBB US, falling hard today and trading below the 200-day average again. Not bullish.

US Credit, CDX IG, spiking higher over past three days. Not bullish.

Tran index having an awful time and trades well below the 200-day average. Not bullish.

Russell falling hard today. Ex leader going dog. Not bullish.

You simply do NOT want to see important sentiment like the ones mentioned in order to stay bullish, at least for the short-term punters. The prudent investor should take a look at cheap optionality as well as having a proper risk management method in place.
