ratings and price targets in the last year

Just a question really .
Over the past year we have had many ratings and targets for Sunshine heart , summer street , craig hallum research , lazard etc .

All these research analysts set a price target of between 18-26 for Sunshine heart . To note these were between the 2nd and third quarter of 2012 . During this time , SSH managed to complete important milestones . unconditional approval to initiate the us trial and the start of the european post trial .

However my question is , All new price targets are now 10 - 12 dollars range Why havent we taken the next step up in price of the share + market cap . Im all with the c-pulse technology and its potential , however im slightly dissapointed that were currently in march 2013 and we have been in a downward spiral ever since rise before the stock offering back in july .

are there advantages for the board to keep the price low ?

Also , outstanding shares are approximately 9.5 million and the float is 2.6 million . yet according to yahoo finance only 3.66% is held by insiders and 15.20% held by institutions . who is holding the rest and is restricted to sell ?

Also , with all the potential , why is it only @ 3.66% held by insiders seems such a small number

to conclude , why hasnt the price of the stock reflected the success/potential of the technology to date . And why have the targets fallen from 18-26 to 10-12 even though were on the right track and achieved important milestones during this time .

All the best to all longs .
