----true facts specific to a stock price movement is its earnings results and guidance every Q. Even if the results are great, it can go down if the markets are tanking. It can also go up during a severe correction -- My point is investors "assume" and make decisions all the time. Facts can be relevant as a subset of assumptions. Its always fluid. Even the Federal reserve have assumptive models which wait on facts to either confirm or negate those models------
You are changing the subject. "DAX and NYSE' are irrelevant to the price of ABB; that is all that was in dispute. Want proof? Take the price of ABB on the Swiss exchange, multiply by the exchange rate which you find on the Kitco page to 4 decimals and compare to the price in New York. REGARDLESS of the US market, or the DAX, the ABB price will be within a few pennies of the Swiss price. ABB is an ADR; the market in the US is immaterial. One can argue about ideas; one cannot argue about facts.
