Now that we know what wave a and b are as a part of the monthly wave 4 correction - I believe the price will reach $154 to conclude wave c. At $154 it is a definite buy.
As an options play- I recommend either/or: 1) Riskier/More Reward - 10/19/18 $165 P (1200% play) 2) Safer - 11/16/18 $165 P (200-190% play)
