(In fact, the real market nadir wouldn't be reached until 6th March the following year, an anniversary that a very few prescient, or lucky, investors may honour by raising a glass of Shipwrecked 1907 Heidsieck champagne.)
Following the trajectory of markets since December 2008 we concluded: "Over the five-year period both equity and bond markets both fell and subsequently rose. There was a delay of nearly three years between the period when the share market started to recover and the bond market bottomed-out, providing a period when an investor could make money in both markets."
And, yes, if investors had timed the markets perfectly during the GFC-induced volatility they would've made serious money - the sad truth is almost no-one would've achieved such perfection. Rather more investors, though, probably bailed out at the bottom and are still playing catch-up.
As the MJW client note puts it: "With hindsight possibly the best and safest strategy was that pursued by investors who not only stayed invested but also topped up their allocation to shares as markets fell. But this strategy needed courage to implement even if one had a prescriptive approach already in place for such an event."
At the time our advice to clients was to stick to their strategies, even if that meant investing more in equities as prices fell to maintain asset allocation ratios: some listened; some didn't.
MJW provides asset consulting including fund manager selection advice to many clients who are usually described as 'institutional' investors. In some ways this is a misleading term as the 'institutions' in question typically represent the interests of a multitude of underlying individual investors, community groups or charities.
The investment decisions of these 'institutions', therefore, have a material effect on, say, the retirement plans of ordinary New Zealanders or the ability of charities to distribute funds to worthy community causes.
Without a doubt, the experience of the GFC has sharpened the skills of New Zealand's institutional investors, although the practical lessons of the crisis have been predictably dull: keep diversified; manage liquidity.
The challenge will be to remember the lessons of the GFC as it fades into history to ensure we all keep evolving into better fund managers and investors.
