SU is oversold and we can see that the Pyramid data is not too bad: LER is good and the stock is close to its Lower Boundary.
However buy statistics show that it is best to buy even lower than the close of Friday.
Short trades do not generate interesting returns either as you can see below the sensitivity analysis of shorting at different prices.
Conclusions: SU is only a Buy trade close to $30.26 with a stop 2.5% lower.
