As I stated "This is purely a mathematical formula with no other factors into play" I am a late comer onto this stock, as soon as the news hit that the oil price went "negative" one tends to ask how more negative can it go? That was the trigger for me.
Those who have been around longer will be able to answer your question better, only time will tell which way the coin toss falls, and in the meantime many more factors will come into play.
Ultimately why does one say its a good time to buy when another has the opposite view and sells?
Why do some ride the trends and others buy for the dividends and franking credits?
It would be impossible to cover every factor, I will leave that to the experts, More than happy for them to come up with a different calculation to mine then we can compare notes.
