Transaction costs in general are higher for:
A) precise float adjustment and more popular indices.
B) precise float adjustment and less popular indices.
C) float adjustment bands and less popular indices.

Your answer: A was incorrect. The correct answer was B) precise float adjustment and less popular indices.

i thought that because more popular indices are more widely followed/used as a benchmark, adding the stock to the more popular indices can increase its price and make replicating the index more expensive
