Liquid tradable securities (or LTS) is a generic phrase for a wide range of financial instruments.
It often differentiates financial instruments that are easily tradable (or tradeable) as opposed to those that require the permission of the company or a signed document that registers the transfer of securities between two market participants.
Equally, a transfer of shares in a collective investment scheme is usually not allowed without the signed consent of the company.
A small subset of collective investment schemes are electronically tradable through stock exchanges (most notably REITs).
[3] LTSs are held in a global note form and deposited with a central securities depository (CSD).
