I'm looking for mid to long term investing, how do i start investing through DBS Vickers and OCBC bluechip?

I understand that generally as a beginner, it always feels like the SGX market is much safer than the US market and that our bluechips 'cannot lose money one'. But if you're 20, you're probably looking for wealth accumulation.

I would advise you open a broker which has access to global markets (US,UK) and consider Index Investing instead (also known as passive investing).

Essentially, you invest in an investment vehicle such as an ETF, which tracks a specific index, in the belief that the market in general trends upwards (due to increasing productivity).

An index is a basket of stocks, that generally is used to represent an economy or a sector. In Singapore, we have the STI, and the US has the S&P500, Nasdaq 100 and Dow Jones. As such, when we invest into an index, the value of our investment increases as the stocks in the index move up which consequently causes the index to move up with it. Historically, the S&P 500 has returned about 9.8% per annum since the 1920s.

For starters, if you're young, looking to accumulate wealth, an S&P 500 ETF (E.g. CSPX, VOO or IVV) or a World Index ETF (IWDA, VEU) is a good place to start.

Also, if you're not certain which broker you want to use, you can check out a comparison of some of your options!​​​

If you are looking to invest in SG market, perhaps a diy reits portfolio will be ideal. But definitely not gonna recommend STI as it doesnt really gain much over time.
Personnally I will suggest either SP500 or ARKK given their potential growth and diversifying holdings.

Just a recommendation on how and where you can invest in:
SG market - Focus on dividend stocks
US Market - Potential growth stocks

As currently I see that you only have around $3k, maybe a strategy which you can use over time is to dca investing into the stocks.
