Is it true that buying the STI in bad times and selling it in good times is far more profitable than buying the S&P 500 over the past 25 years? How do you prove this?

Private investor Bernard Tan made this claim on the ST Invest section on 23.2.2020. Buying the S&P during bad times and selling it during good times seems more profitable imo, as it's performance seems to be better than the STI. Can any expert provide testing data to prove the case?

      even less so then we retail investors. How can one have a definition of 'bad times' and 'good times' as entry/exit points? This would be the basis to answer your question for data.

      There could be a hint in the following longterm chart (STI versus SP500), that suggests STI had more volatility, but then remains the question: how could one have known, the optium entry/exit points (my feeling: completely impossible, but only post hoc)
