"As of October 7, Anavex common stock will trade under the ticker symbol AVXLD for a period of 20 business days. After that time or earlier once NASDAQ approves the uplisting requirements, the “D” will be removed and our Company's symbol will once again be AVXL. A new CUSIP number will be assigned to the Company's common stock as a result of the reverse split. "

The 20th day as a temp symbol (AVXLD) would have been November 3rd.

Actually Oct 28th was AVXLD last day, and the peak was actually November 2nd. Then the stock dropped sharply to 3.24 on Nov 17th.

So, as it turns out, the stock price movement didn't correspond so tightly to the reverse split. Price action should be crazy, but there's no dependable play here, at least for me.
