Bangkok: The Stock Exchange of Thailand (SET) has announced that Delta Electronics (Thailand) Public Company Limited, known as “DELTA,” will be subject to Level 1 trading supervision measures starting October 10, 2025. This decision comes as a result of the ongoing surge in the stock’s price and trading volume, which has the potential to impact the overall market.

According to Thai News Agency, the SET’s decision to impose trading supervision measures on DELTA shares is due to the significant price and trading volume increases, despite positive information in the technology sector and expectations of strong earnings from power electronics products for data centers. The stock’s price-to-earnings (P/E) and price-to-book value (P/BV) ratios have reached 135.49 and 29.32, respectively, which could affect trading conditions across the market.

On October 9, 2025, DELTA shares closed at a new high of 197.50 baht, with an intraday high of 201 baht, and a trading value of 4,514 million baht. The stock’s market capitalization now accounts for 14.87% of the SET Market Cap, influencing the index by 5.9 points.

The company clarified through the Stock Exchange of Thailand on October 1, 2025, that despite the significant change in trading conditions, there have been no undisclosed developments affecting the stock’s fundamental factors. Investors interested in trading DELTA securities must use a cash balance account, requiring 100% cash purchase, and are prohibited from calculating the trading limit.

Reporters noted that DELTA shares closed on October 9 at 197.50 baht, marking an increase of 6.00 baht or 3.13%, with a trading value of 4,514.28 million baht.
