Not my normal kind of stalk idea as the growth tends to be good, but generally not explosive.
In this case, the stock just completed a really nice pullback, formed a nice base level of support and is making its way higher.
The chart structure is a variant of the triangle patterns that I love so much. You could also see it as a Cup & Handle pattern
Either way, feel free to stalk long entries on daily or lower timeframes.
If for some reason price collapses back below the support box, remove Cubesmart from your stalk list from the time being.
