out of curiosity how did your intrinsic value estimates move during this time?
Did most of the damage occur during the GFC?
I ask this not to be 'cocky' but because i am always interested when it comes to this sought of thing.
One of the lessons i have learnt is that when the economy moves from growth to recession it can have a disproportinal effect on movements in intrinsic value because as you have stated estimates of intrinsic value have to be contain at least some quantitative measures. Its hard to see the durability effect of the variables that go into those quantitative measures given that australia has not really had a recession in 15 odd years.
In the current environment in australia this may be a good point to head for 'value investors'.
The period was around 1998 to 2004. I had roughly 6 positions from memory (NAB, CBA, Tabcorp, Aristocrat, Telstra, and one or two others I've forgotten, in roughly equal measure). The standout i.v. read to me back then was Aristocrat, throwing off free cash flow like froth from a champagne bottle, and showing an i.v. around twice the then share price, or so it seemed.
Until, when was it, 2002? Aristocrat's CFO suddenly and mysteriously resigned and the board soon admitted that they'd fraudulently concealed massive losses from their South American ventures.
Where the hell were the auditors and regulators, I asked myself in abject horror?
Anyway, I still came out well ahead in Aristocrat myself, but as you'd remember it all resulted in a class-action suit by their then more recent shareholders.
(Buffett I know would have cautioned to stay away from heavily government-regulated sectors, but that was not the problem Aristocrat faced so much back then. Of course, both Tabcorp and Aristocrat suffered dearly at the hand of government more recently with smoking bans in pubs, but that was long after my time in them, and they will no doubt suffer more greatly in the future thanks to Xenophon and the Greens I'm sure. I'm no longer though the agnostic on poker machines I was back then: Ive come to think they are dangerously addictive, and wouldn't invest in these companies now even if they did show outstanding i.v. to price ratios, which of course they don't.)
My emphasis was always on the quantitative side, although I did cursorily trace who was who on which boards back then. As regards the qualitative side, I think it was Sir Arvi Parbo who once said around that time that you could count the world-class CEOs in Australia on one hand.
In any event, observing each new episode of corporate shenanigans on these reporting shores, I ultimately came to the conclusion as stated at length above that the Australian stockmarket was a fool's errand, and took everything I had and went into property (wishing I'd done it from the outset).
End note: It was Noel Whittaker's ''Making Money Made Simple" that turned on the financial 'lights' for me in around '97, but it was also his emphasis on stocks vs property that led me astray. The wife and I still remember with a huge smile saving our very first $ 5,000 together around 15 years ago (just after I'd read Whittaker) and 'investing' it excitedly in a 3-month term deposit, to then take it out with about $250 interest and investing it all in the float of National Mutual, which gave us a 20% return (as I recall, in just another 3 months or so). Happy days, but a in retrospect, a major strategic wealth-building mistake to go into shares rather than property!
