ETCG over Eth Classic, Sharply Diverging

When you look at the daily candles for the public Ethereum Classic fund, ETCG, it appears parabolic. But when overlaid on Ethereum Classic itself, we see that it has diverged sharply in this direction away from the cryptocurrency it tracks. My account has gone up 54% in a week, but is this going to continue or come down with a parabolic correction sooner than later?
