How do you buy DBS stock?

Whether it's DBS or some other companies shares, I will buy via DBS Vickers Cash UpFront ($10 commision per trade + SGX Clearing Fee + GST etc.). Yes, the stock will be held in your CDP.

However if you plan to get share financing (i.e. margin trading), then DBS will not allow you to do that on their stock 😏

Here's their list of marginable securities:

Not really certain of the intent in asking this question but there are 2 main ways that you can buy DBS stocks - through a custodian account (i.e. Stanchart) or through a CDP-linked brokerage account (i.e. DBS vickers). I use the latter for my trades.
