Some stocks (e.g. 1066.HK) are quoted at zero

From time to time, I see various stocks with a last price at 0. This morning 1066.HK, 1358.HK, 1908.HK of a few HKEX stocks I was checking.

Dear dpc,

Please note that Shandong Weigao Group Medical Polymer Co Ltd (1066.HK) is possibly a foreign stock, similar to an ADR.

For all discrepancies between the Currency Codes of the Price Data and Fundamental Data, the stock's Previous Close is marked Zero; so as to prevent it from being accidentally cleared on GrahamValue's screeners.

Thank you for your question!
