That I can't even begin to guess. Maybe the mass media will pick up on it and it will happen in a week. Or maybe I'm wrong and the media won't care and they'll have to earn their way to $25.00 the old fashioned way with several quarters of increased earnings per share with a reasonable PE ratio.
I think it will be somewhere in the middle. As the production and profitability of one machine becomes easier to understand, then investors and institutions can extrapolate that outward more easily. Maybe by end of this year? Maybe sooner? Maybe this time next year? Dunno. Price of oil and general market are two huge variables as well. If we get $120 oil and a raging bull market then it will happen muuuuuuuuuuuch sooner than say $50 oil and a bear market for example.
