Sudden surge in Sino Env and Technics Oil & Gas share price

Today, Sino Env and Technics Oil & Gas share price suddenly jumped.

Sino jumped 0.15 to 1.4
Technics Oil & Gas jumped 0.12 to 0.61

For Technics, in reply to SGX, there's no undisclosed information that can explain the trading pattern. But it does say that "The Company however wishes to point out that in the ordinary course of its business, it actively explores possible new investments and other business opportunities in line with its strategy to expand its business and improve shareholders’ returns."

For Sino Env, the company promptly requested for trading halt. In the reply to SGX, company said it would announce promptly.

Market does know something extra, sometime faster than the announcement. Some good news are brewing, that's why the sudden surge in share price. The listed company should spend extra effort to ensure that the insider information is not leaked out before the announcement. Those first movers have gained the unfair advantage against other market players.
