Cede is the float not held by people in their own name. It is also called shares held in Street name. Every single public companies float clears through CEDE, which is also known as the Depository Trust Company. DTC for short. That's where the slang term just DTC the shares came from, which is electronically transferring shares directly from the TA to someones brokerage account. So simply put, Cede is the clearing house for all free trading shares electronically entered into the trading system....versus paper certs held by people or corporations which can also be free trading. The shares in paper stock form don't become part of Cede's share count until that person deposits their stock cert into a brokerage account.
