RE:RE:RE:RE:RE:PCLO Officially Added to NA Marijuana IndexThey can't be rebalancing their entire asset on just one specific day.
I had a look at TER which was a similar thinly traded stock. It ran for a 2 weeks leading to March 15, with an increasing volume. It's clear Horizon, when adding a new exposure, does its rebalance over at least 5 to 10 trading days leading up to the confirmation that rebalance has occured.
