If that were the case don't you think one employee would come forward? Just one disgruntled employee out of one thousand five hundred is all it would take. There is no conspiracy to naked short sell little old SRGE. Two people can't keep a secret. How could fifteen hundred? Either that or all of Knight Capital employees are fully gruntled ;)
Yup NITE has many employees.
Everything I say should be taken as an honest opinion and not necesarily taken as fact unless supported by links to a reliable source. I could be anyone, take what I say with a grain of salt. Anything I say of interest is purely coincidental.
