Compare the prices for most of the SGX stocks in 1996 and now, you will know what I mean.
However, if you compare prices for 2001 (after 911) and 2011, for 100k you invested in 2001, you may get back 300k in 2011. So it all depends on your entry level (or entry year) and what is going to happen when you exit.
If you enter in 2001, STI was 1200. If you enter now, STI is 2500. In 2011 and 2016, STI should be 800 or 3500????? I don't know the answer, do you know???
