If yes, does it mean "very much liked by people"?
"I'd like to sell 3,000 GDRs of Samsung Electronics preferred."
That's stock market terminology.
In the stock market, GDR (per Investopedia) stands for "global depositary receipt" and
represents a bank certificate issued in more than one country for shares in a foreign company. The shares are held by a foreign branch of an international bank. The shares trade as domestic shares, but are offered for sale globally through the various bank branches. The term GDR is used throughout the globe and designates any foreign firm that trades on an exchange outside its home country.
Also according to Investopedia, you have preferred stocks, which can also be preferred shares:
A preferred stock is a class of ownership in a corporation that has a higher claim on its assets and earnings than common stock. Preferred shares generally have a dividend that must be paid out before dividends to common shareholders, and the shares usually do not carry voting rights.
So, the sentence could have read:
I'd like to sell 3,000 GDRs worth of Samsung Electronics preferred shares.
However, as has been noted in a comment, shares can be dropped and the sentence understood without it.
