It depends on your risk tolerance, age, and some other factors. But to generalize the answer, this is what I'd do in the CURRENT market situation 1. Hoard the cash for now, the market is going very irrational at the moment (unemployment is rising, trade volume is dropping, interest is dropping, and the stock market is RISING?????). it doesn't take a genius to know that now is not the right time to invest 2. After some correction, perhaps market drop a further 10% - 20% (I don't know when, but perhaps a few months later), then I will invest 50% of my money and keep the remaining 50% 3. I will buy in (lump sum) some countries and sector ETF such as SPDR® S&P 500 ETF Trust (SPY), iShares MSCI China ETF (MCHI), Vanguard FTSE Emerging Markets ETF (VWO), Vanguard REIT ETF (VNQ), Fidelity® MSCI Information Tech ETF (FTEC). 10% each with the 50%. 4. The remaining 50% I will use it for Dollar Cost Average every month ($1,000 every month for 5 months). However, with just $1,000, the brokerage will be insane hence DO NOT DCA on your brokerage accounts such as DBS Vickers, Saxi Capital etc. I'd use Regular Savings Plan (You can choose from OCBC, POSB, POEMS or FSMOne). Personally, I'd go with FSMOne RSP due to their low fee. I will invest $250 each month into iShares Core S&P 500 ETF (IVV), Fidelity® MSCI Information Tech ETF (FTEC), Vanguard FTSE Emerging Markets ETF (VWO) and Invesco China Technology ETF (CQQQ), that makes up to a total of $1,000 every month. Continue doing this for 5 months until you invested your remaining $5,000. 5. Depending on market condition and what you plan to do and you financial situation, you can continue investing the lump sum to buy stocks you like (Zoom, Amazon, Facebook, DBS, whatever) or continue your DCA into FSMOne RSP, or stop investing altogether. That sums up what I would do if I have $10,000 to invest, cheers!
