How do I know if my portfolio is about to lose money?

An inescapable path to becoming a successful investor is to learn how to become a lifelong student. Learn from other investor's success and mistakes. Learn how they made the money, not how they spent it. Place value on value, buy assets that you know are underpriced and sell them for a higher value. Always have healthy Skpeticism which is very hard to acquire as the world is full of malice. Lastly but not the least is to sharpen your analytical ability as being able to analyze what is going on is very crucial to becoming a good investor.

There are many ways to invest your money. You could invest it by opening a high yeild savings account for emergency purposes or you could invest all of it on CPF. There is also an option of dividing the money and putting half of it in your savings account and putting half in CPF. Eitherway it all depends on your current financial status and necessities.

Just like in any country, there aren't many investments that guarantee your principal as well as returns in Singapore but of those that do, you should be very careful of scams. One other thing to understand is that when you get to enjoy such safety in your investments and visibility in your cashflows, you need to be prepared to accept a rate of return that is close to the risk-free rate. Your first bet is to invest on Singapore Government Treasury bills and/or Singapore Government Bonds. You can also try investing on saving plans or fixed deposits but the returns are low. If you want higher returns then you really need to invest on high risk investments.

Your interpretations are correct but we can look deeper into its characteristics. A bond has a face value which is the amount the bond will be worth at maturity and the amount the bond issuer uses when calculating interest payments. A bond has a coupon rate which is similar to interest rates. A bond shouls always have a maturity date which is self explanatory. Probobly the most important characteristic is the issue price which is the original price the issuer sells the bond.

A bond is debt instrument that a government or a company issues to raise money.. Bonds are low-risk, stable and predictable investment. Investors earn from this because the investors act as a lender and the government acts as the borrower.

At first it might sound lika a hoax but since this is Singapore where possibilities are limitless. There is a company called Circles.Life that offers a free sim only plan. Their plan includes 1GB of data, 30min talk time and 10 SMS every month for S$0. This is perfect for someone who just needs a sim card for emergency purposes or someone who needs a line so they can be reached but does not use their phone much. TPG also offers one which includes 2G of data/day but you can;t use it for calls and SMS.
