How to do long term investment as a NSF? As a NSF, with limited savings of a few thousand dollar, what should my next steps be in order to attain more money?

Adding on to what Andy Chan has mentioned:

The easiest way to invest for the long term is roboadvisor because it is very diversified, low capital, little time commitment. It is a good starting point and a good foundation to build on your portfolio. Investment is about managing your risk-reward appetite. If you are adventurous and wants to have generated more capital/profit, you could invest in stocks or bonds. For e.g portfolio of 70% ETF,10% cash, 20% stock pick. Thus, I would say that it will be great to have some roboadvisor /ETFs to ensure safer capital growth

(Value) Investing = Gambling?

Gambling is usually associated with the words 'risky'. Risk comes from not knowing anything or venturing without any plans. For example, An investor is willing to pay you for climbing Mount Everest.

Choice A: Awarded 1 billion if you go the next day

Choice B: awarded 0.5 billion if you went 2 years later

Choice C: Awarded 10 Million if you went 3 years later with professional coach training you and assisting you

You may not choose choice A because you are high likely to die

You would choose Choice C over choice B because you have time to prepare yourself.

Same goes for investing. The more knowledge/ data you have about investment or company, the confident you will be.

Value investing is the process of choosing underpriced stocks appeared at the marketplace. There are ways to calculate the stock value in the subsequent year. The calculation is based on historical financial statements

Example: Stock A's intrinsic value is $1 while the stock A's market price is $0.50..

You will then have to wait till the market realise the stock's true value before you sell.

Now, the idea of value investing has evolved. Learning how to choose a great company. This means selecting great fundamentals, great economic moat, great management, etc

Anyway, all the best

Since u're still young, with a long time horizon and supposedly high risk appetite, go for equities. dca monthly, pump and forget
