TSX price movement has also been leading the AMEX. I have been noticing that KRY PPS does its usual thing and then when something happens positively on the TSX there is a delayed reaction of as much as an hour which is then realized on the AMEX. Often the AMEX PPS will shoot past the TSX price and then settle back until the next move.

Don't know if anyone else is seeing a connection here, but I've seen it the last few weeks. The PPS on AMex should be close but under the TSX and they'll equalize out any imbalance on low volume days, but I found this interesting to observe and used it when KRY was moving down from $2.15 to $2.10 an AMEX while the KRY TSX was moving up. Maybe I got lucky but I made a trade on that observation at AMEX $2.10 falling ($2.11 I entered) with TSX $2.19 rising. It slung past TSX which was at $2.25 then settled to $2.23 before moving back up about 30 minutes after TSX continued its up movement. Watching both I was able to make some nice change.

Just another angle.
