Taiwan-listed Century Iron and Steel (5314) has locked at its daily price ceiling for a fourth day running, a big win for shareholders but a sign of froth for anyone chasing it now.

• The stock jumped straight to its limit at the open, with buy orders far outnumbering the shares available to trade.
• Traders are piling in on strong first-half sales and profit growth.
• The company is pushing into AI health tech, new-generation drones, and unmanned vehicles, so the market is treating it as a turnaround growth story.
• A recent share price correction and a stock dividend left the price low enough to attract smaller investors.
• Some investors are warning the run has gone too far too fast, and that whoever buys last gets hurt.

Outlook: The buying pressure looks set to continue in the very short term, but the risk of a sharp reversal rises with every limit-up day.
