how can you compare, your spy is privately held whereas SGS is MAS held, can you see the risk difference? SGS is like having a savings account with the gahment, risk tolerance equates to near zero.
If US market tanks, the whole world, including sinkapore, is dragged down. The guarantee by MAS is as good as toilet paper.
I will take an extra 5 percentage point over the SGS returns for the miniscule additional risk, if any, by putting my money on SPY.
7 percent (SPY) vs 2.5 percent (SGS or CPF) over 30 years for an annual investment of $10k
SPY returns $1.3 million
SGS returns $450k
Returns given up for that 'risk' is
$850,000, nearly 6X the returns of SGS. Are you going to be an idiot to give that much up?
Over the 30 year period, the SPY has gone through multiple bubble bursts and recessions, including the recent Great Recession.
