# Market Relativity Theory?

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.

Identify flaws.

• What on earth does `statistically significant` mean in this question?

• I'm very well versed in the meaning of `statistically significant` in general. Your use in the above paragraphs is somewhere between confusing and incorrect, though. You're at minimum missing a term between `statistically significant` and `to`. Do you mean `significantly different`, or `significantly correlated`, or ... something else? You also cannot take a single specific instance and make any sort of "significant" statement about it; you can only use significance testing on a dataset of many points. You might make a prediction that a value will be similar or different (cont)

• (cont) but you would not use the words `statistically significant` with that prediction; you might describe the accuracy of that prediction, perhaps.

• I suggest you read a bit more on statistical measures, or take a class or something. You're still making zero sense: you need a comparison noun that is statistically significant. The correlation is significant. The difference is significant. Etc. Significant is an adjective, and statistically is an adverb.
