I accept that you have a vivid imagination; prefer to base my investment upon tangible factors (e.g. DCF's & physics) and what is known and then use logic to speculate on what is unknown. As was quoted by Rumsfeld many years ago there are "known knowns, kwown unknown & unknown unknowns" I prefer to base my investments on the first two the "unknown unknowns" can be either good or bad and not worth exercising your mind over. I guess you prefer clairvoyants and tea leaves to chase you rabbits - each to their own. I prefer logic and reality.
