Singapore's shares slid at the close on Tuesday, tracking regional losses as concerns over AI-related investments led to heavy selling in major chipmakers.

The Straits Times Index (STI), a key benchmark for the Singapore Exchange, ranged between 5,380.12 and 5,423.91 throughout the day. It ended the session at 5,404.02, down 7.98 points or 0.15% compared to Friday's close.

On the corporate front, shares of Skylink (SGX:XZB) closed over 6% lower even as it completed the fully subscribed issuance of SG$5 million in two-year, unlisted, non-convertible and non-transferable hire-purchase bonds.

Centurion (SGX:OU8) was down nearly 2% at the close as it completed the acquisition of a worker accommodation business and land assets in Karratha, Australia.

Meanwhile, First REIT (SGX:AW9U) redeemed SG$100 million in 3.25% guaranteed bonds due 2027, according to a Monday Singapore bourse filing.
