Zclassic market cap vs price

I've got a few zclassic coins in anticipation of the upcoming bitcoin private fork and have been keeping a close eye on the price. I got in quite late at about $180 a few days ago. I've seen it go upto about $240 and go down to about $166 now. That's a bit disappointing but I accept that people are taking profits.

The thing that's puzzled me today is the market cap has gone up by 200m on coin market cap, but the price is still at $166. Anyone have an idea why its done that?
