Enhydris is disclosed right at the top of the page just a bunch of writers who are getting paid by clients to bash, pump, or speculate according to the clients wishes. Their opinions and $2 will get you 12 oz. of coffee at Starbucks. Any resemblance between their articles and fact is purely coincidental. The bashing of Areniacs in the article is a tell tale sign this was "message sending", not independent journalism.
Technically, if the share price hits $14.00, you better not sell, since looking at the max year chart for ARNA, there is very little resistance between $14.00 and $47 and change, ARNA's max year high. Seeking Alpha want people to settle for $14.00. Technical analysis tells you to wait for the 40's to sell, IF the share price breaks through major resistance between $12.50 and $13.50.
Shorts pray on weak retail longs, nothing more. So what they do is they short a stock while the company is in transition or in a state where its not fully rolling yet, This way any "no news" day they can spin into a negative news day, any negative news day they can plaster it EVERYWHERE, and any positive news day, those days aren't spoken of at all. Weak investors get scared off quick, its only a # until you sell is what a friend told me. So it doesn't matter if this stock is $4 or $40 today, unless I am buying or selling at either level, the number isn't important.
