Pinned straw:
I first bought CDA at $1.85 13 years ago, so each of the past 2 days has been a spiffypop for me, not a big achievement for any long-held companies, I guess. My holding history with CDA has helped me crystallise my attitude to selling out of a company - I don't care about valuation ratios, high or low, I only care that the company continues a trajectory of profitable growth and is lead by a capable and trustworthy management team.
In the early years of my ownership, I remember being down 50%, and this was even before African coups dented their gold detector sales. Now the company is flying high thanks to a favourable backdrop of rising gold prices and increased defence spending, so in a year or two it will doubtless fall out of favour again, and multiples will compress. This is all just market sentiment as far as I am concerned, to which I have grown fairly impervious. That's my definition of high conviction.
