If LPC is being used at these levels then something isn't good.
". 5,787,235 shares of common stock registered under the 2016 Registration Statement have been issued to Lincoln Park and 5,654,700 have been resold by Lincoln Park as of the date of this prospectus. "
So, as to the first part of your sentence, shares were being put to LPC at even lower prices than the present. I seriously doubt they hired a company to make sure shareholders voted for authorization of 5 million more shares if they didn't plan on using it.
As to the second part of your sentence, it's probably just because data is so damn good that they are afraid that if they tell anyone about it, there will be a hostile takeover. Ya, that's it, a hostile takeover prevention strategy. Seems reasonable, right?
LPC has been used over and over the last few years as the price has increased. He can sell some now and sell some when it goes up a little bit more and sell some more when it goes up a little bit more and so on and so on and so on he will be selling all the way up to LPC.
What Misling is probably doing by selling shares down at these levels is taking care of the institutions that will be writing research reports on behalf of Anavex and doing all the good things that institutions do to help promote the stock. This is their version of an IPO which they obviously missed out on by the way they came public
