JDSU had fuel today for 3 reasons:
1) the generalised intraday reversal in the market
2) the fact that JDSU had undergone a classic intraday consolidation breakout (on a tickchart)
3) the fact that JDSU had broken through its 50 day moving average
The combination of these 3 factors probably helped JDSU on its way... a coalescence of complementary factors often has this effect, and JDSU is an example of the trading Gods smiling kindly...
