Q: I’m looking to increase both US and international exposure in a TFSA account, which is focused on long term growth. Knowing you can't provide specific advice, I'm curious: In today's volatile market, is it wiser to slowly add to each investment or commit to a full position all at once?

5i Research Answer:

Mathematically, investing 'all at once' tends to work better as it maximizes the time an investor is in the market and receiving returns. Realistically we think it is easiest and best for most investors to average in over a period of time. The key is that the investor actually continues to add exposure to the market opposed to just staying in cash. We would be fine with slowly adding.
