I have this calculator I made for myself to see what different financial decisions or investments would look like. I put some of your details (of which some I had to assume) into the calculator to hopefully argue that you might want to consider investing in training yourself as opposed to in markets. This doesn't necessarily mean completing secondary and uni, but it could also be trades and vocations that you enjoy.
Assume you are an average investor. You just invest in the Hong Kong basket of stocks with extra cash you have.
(Historical 2800.hk as an estimate with 10% return and 20% standard deviation)
Situation 1.
Age: 22
Income: 16,000 (median income for secondary education attainment 4-7)
Savings: 130,000
Monthly Spending: 6,000
Monthly Savings: 10,000
Situation 2
Age: 26
Income: 26,400 (median income for tertiary education attainment)
Savings: 0
Monthly Spending: 7,000
Monthly Savings: 19,400
You delay investing in the market and spend your savings training yourself to hopefully earn a more competitive salary, hopefully saving much more a month when you're done than you could in your current situation.
Situation A Simulation Results:
(Numbers are a little different from the first table because I had to re-run the monte-carlo simulation and things)
Situation B Simulation Results:
As you can hopefully see from the simulation, even though in situation B, you started investing later, and with less savings (just your monthly contribution), you still ended up much better off later in life. Maybe not so much by 30, but definitely after that. Additionally, your risk of running out of cash in case you are entering the market at a bad time is also less at 1.4% as opposed to 34%.
In short, I just want you to consider spending your savings on self-improvement such that you can save even more in for the future. It will have a bigger impact than picking the right investments which nobody can guarantee. I know it might seem scary because of how hard you fought to save as much as you have so far. I'm not saying definitely do it, but consider it and talk to more people about it. Hopefully more people in the forum can advice. This is just my opinion.
Maybe later on you can focus on your investing decisions to try an improve your risk/return, but that might be better for later.
