The Nasdaq held support and led the market higher on Friday. Even though Thursday's decline was quite drastic, the Nasdaq never broke support from its May lows and the medium-term uptrend remains. Nasdaq support is just above 2500 and extends back to the January highs. The index established a resistance zone around 2510 and this resistance zone turned into support during May. This is a classis tenet of technical analysis: broken resistance turns into support. While this week's three day plunge was the sharpest decline since late February, the index is still holding support and I would not put on my bear hat until a break below 2500.
