Taiwan's exchanges are clamping down on 8 heavily traded stocks and flagging 46 more, a warning sign for speculators chasing hot small-caps.

• I-Chiun Precision, Global Lighting and six related listings go under trading curbs starting Aug 27.
• During the curb period, trades are matched by hand only once every two minutes instead of continuously.
• Most curbs run through Sept 2; Global Lighting gets a longer seven-day stretch because too much of its volume came from day traders.
• Another 46 stocks, including PharmaEssentia and LandMark Optoelectronics, were put on the watch list for unusual price moves.

Outlook: The curbs usually cool the frenzy for a few days, and stocks that keep spiking after the period ends risk being punished again.
