Singapore

SHARES of Catalist-listed healthcare players Medtecs International Corporation and UG Healthcare tumbled on Monday, prompting separate queries from the Singapore Exchange (SGX) over the "unusual price movements" for both counters.

Separately, the duo's healthcare peer Biolidics halted trading following a share surge on the same day. Prior to the trading halt, the counter was trading at S$0.52, up 11 cents or 26.8 per cent as at 12.18pm, compared with last Thursday's closing price of S$0.41.
