Thank you for helping this "less than expert knowledge" octogenarian. I really appreciate your postings along with the many others that are so very experienced and knowledgeable on this board. I have a considerably large position in AVXL in a special dedicated estate plan to be used for humanitarian purposes in the many years ( 10-20-30 years and more hopefully) in the future should the Sigma 1 receptor platform be successful. I told my banker in 2015 that this is a "Babe Ruth" type investment for that purpose. As long as this is taking it appears that I will have to observe the results from my after life on earth (prayerfully) position.
To say this a little differently, this often times has to do with reporting large transactions. Typically these are block trades (large trades) which are firm to firm, so it trades off the tape and at a different price. These trades happen during the trading day but don't show up on the tape (level 2).
This is why you’ll see them reported after the cash close. I equate this to a bookkeeping function at the end of the day.
