Use of apostrophes
Is the following correct or should it be classes'? "cross-asset class’s correlations"
If there is only one class being assessed, it would be "class' " but plural is "classes' "
The sentence should be read as "cross-asset classes correlations". This is to indicate that there are several classes. On the other hand, if it were to indicate possession, then it would be correct to use the apostrophe before adding letter 's'.
Sarahngoche is correct. If possible, it would be better to reconstruct the phrase to "the correlation of cross-asset classes."
Classes w/o an apostrophe.
