Would it be fair to assume this:
High market-cap securities will usually perform influenced to some extent by the market/Index fund they are currently traded on.
For example; the Turkish Borsa Istanbul 100 stock Index finished the last trading day at 1.38%. It would be safe to assume that some of the largest companies trading in Turkey finish the same day with returns in a range statistically significant to the fund. For argument's sake keep Koc Holdings, which finished the same trading day with a 1.72% return in mind.
Elaborating on this concept, moreover, imagine hypothetically that Koc Holdings was traded on the NYSE. If the NYSE closes out the same trading day with returns of -2.50%, NYSE:Koc Holdings will finish the day on this market with returns statistically significant to those of the NYSE.
