I would use my SRS to invest in SPDR S&P 500 ETF (S27.SI) because it offers diversified exposure to the U.S. market and GLD as a hedge against inflation, both to me are solid choice for long-term growth.
My thoughts are to go for long term investment plans and review it regularly since situations are ever changing esp with covid and ongoing war. Certainly hope that the war ends soon and may there be peace and loving kindness on Earth.
