All singapore stocks... First you need to know are you going for growth or dividend. If you are young, i suggest growth investment which is US market.

I recommend reading extensively to find out a method you are most interested in and more likely to adopt. Each of us here has different preferences and may not be suitable for you. The counters you have listed above are all from various sectors and different business and it'll take a super long time to do an evaluation.

Another consideration can be to just buy all. You can have stake in 30 of Singapore's largest companies when you invest into the Straits Times Index. You'll have to research into that yourself too, still need to do your own homework.
