The chart u mention in RCF has a narrow cup (ideally we want a rounding cup) and handle corrected more than 50%, something like 61.8% down to 45.5 before recovering.
Having said all that if and when the move comes about it will be a secular move in all companies. Something similar to sugar sector. And this is provided the move materialises. 
Many a times in these sectoral moves the more dirty and lagging companies tend to provide the maximum moves. But to be on safer side to avoid too much capital loss in case the thesis doesnt work out, it is better to stick to better quality companies.
