ARKG broke out of the parallel channel with strong volume (over 110% tan average 10-day volume).
When there is a break-out, the 5sma tends to be a good rule of thumb to follow the short-term trend; and not lose to much if there is a failed breakout.
RSI shows we are still not overbought at 67; but with strong buying.
Using the bottom level of the parallel channel to calculate a measured move; puts ARKG around $75.
