Sino Biopharmaceutical shares sink

Chinese vaccine maker Sino Biopharmaceutical fell by 14 percent to its lowest level since April, after its third-quarter earnings missed expectations.

The stock pared the drop to 11 percent as of 9:46 a.m. local time, its biggest decline since March.

That’s set to be the worst reaction to any quarterly earnings reports going back to March 2010, according to data compiled by Bloomberg.

Sino Biopharm was among the Hang Seng Index’s top performers in the first half of the year, surging by 34 percent. The shares have lost more than a third of their value since a record in late July.
