How should my investment portfolio be like?

Just AVOID investing in STI index in your initial investing phase or blue-bruised local chips (etc singtel/singpost) and you are already half way there

How to craft your portfolio

1) define your timeline and financial goal.
Eg. Now u got $10k, u want to get $50k in 5years OR i want to have a yearly passive income of $1k in 2 years etc

2) Select your instruments. ETF, stock, robo, unit trust. (No insurance saving plan, please🙅‍♂️)

3) Roughly calculate based on the annual return, see ur selection can achieve your goal (1), allocate accordingly.

My portfolio (roughly)

70% US stock + ETF (Tech heavy) + 30% SG reits, bank fixed income fund

Amzn, goog, tsla, msft, appl, XLK, XLY, XLC

Individual reits, reit etf, CLR, 3 banks, allianz growth & income fund.

LIFE HACK
If you get too confuse, and want to keep it simple, just Buy and Hold 1 x S&P500 ETF. Will save all the trouble.
