Exact Sciences is a biotech stock showing high relative strength.
Following a 50% jump in January, the stock is tightening with pullbacks getting shallower from left to right.
This is a sign of seller digestion which we often see before a new breakout to the upside.
EXAS is also finding support at key moving averages which appear to be holding up the stock.
I would consider buying on a breakout above $69.
