I brought one below share

#6   April 30, 2015 13:06:35   1   $3 USD   $0.21 USD   $0 USD   NP   Completed Date : April 30, 2015 12:30:02
Status : Complete

Now status says complete but balance shows only my earning 0.21USD but where is my initial investment $3?

I'm confused how this system works. Please help to clarify
