I'll give you a list of pros and cons.
Tip of the day: index investing
If you want an easy approach to investing without having to research the companies to invest into, then I recommend you invest into index stocks. This is also advised by Warren Buffett, because index investing is so simple, and index funds, once normalized, has only gone up through the years...ON TOP of dividend payouts and multiple depressions.
Downside to index fund investing is that the dividend yield tends to be very, very low. Singapore's STI ETF dividend yield is about 2.6%.
But it is very, very, very safe and very defensive.
It'd depend on your investing philosophy, approach, how hands-off/optimized you want your investment to be etc. If you are a very, very busy person and/or want 100% safe - then go with index investing.
