JDST was at 48 at the same point June 24th last year. 13 now GDXJ is at the same price it is now. 35 dollars in decay.
JNUG was 21, 12 now So JNUG has decayed 9.00 in that period of time. The inverse 3x JDST has much more decay. This is the power of compounding percentages.
These are trend and scalping tools. Not investments.
