Social games giant Zynga has once again seen its share price plummet on the stock market, hitting a new low yesterday.

Zynga shares fell 10.2 per cent yesterday, their value dipping below USD$5 for the first time since they were floated at around USD$10 per share last December.

In response, NASDAQ has blocked traders from making short sales on the company until Friday.

The shares closed at USD$4.97 last night.

Zynga's daily active users dropped 8.2 percent to 54.2 million in May, but have seen a slight resurgence in the past week, taking that number back to nearly 58 million.
