This is funny as hell. You know that the AAPL chart is heavily arbitraged against the futures contract on GLOBEX. This means that your little argument that the AAPL chart is "randomly constructed" applies to the index as well (pretty obvious).
Charlatan, it applies to anything short-term, such as intra-day charts etc.
Actually, the index value is completely determined by the net effect of capital flows into and out of equities (globally) and fixed income instruments (global as well), cash and brokerage accounts, margin accounts, hedging activity, sector rotation of funds, and plenty of other inflow and outflow.
Charlatan, I accept this but you cannot sit there and predict how these interact and the net result of the future from these things especially inside of a intra-day chart. Unless you have all the knowledge like a God and you can see it from a different dimension. Are you an all-knowing god? NO. Randomness is INCOMPLETE INFORMATION which is PERVASIVE in a intra-day/daily chart 99.9999999999999% of the time.
