While I normally don't try to "time the market", I occasionally succumb to temptation when it seems there is lots of downside risk and little upside potential. I did that with our SMSF Investment in Feb 2020 (when we switched from Vanguard 'high growth' to a 50:50 mix of 'conservative' and 'bond' funds just before the developing global pandemic started to impact share markets around the world)
