Strong suggest anyone genuinely interested in understanding how OCA's business & profitability/loss model works to go through this presentation by OCA.
The presentation was made in 1979 (before the surge in sp in late 2019/early 2020, the collapse in 2020 and then, spectacular sp increase in 2020/early 2021) and is still as relevant today as it was then in understanding OCA.
In particular, go through pages 25 to 30 and it should become clear why OCA is so out of favour.
