more of sg stocks in general rather than best counter

people say the sti etf is a slow moving etf that almost stays stagnant throughout the years. yes, during market positivity and peacefulness, say precovid era, it might have not been too aggressive in growth like certain US' etfs. however, I think the sti etf is a particularly good index etf to invest in especially when it drops greatly in times of turbulence (eg COVID 2020 period). the great drop of the etf ensures a good buffer for a subsequent rebound in prices. Moreover, its stability and reliability gives it a fair chance of recovery during economic recovery. hence, I do think the etf is a good long term investment esp in times of market crashes. moreover, its dividends are attractive.

strategy wise, I'll check what's the avg price and highest price point and when it drops way below this avg price point in times of market crashes, I feel it's a good time to go in. this ensures a high safety net for recovery and when it hits near its high point, will sell it.
