Why was this question “Why do bond markets close slightly early (at 2 p.m. ET) on December 31 whereas the stock market closes at the regular time? [closed] ” closed as opinion-based?
There could be some objective answer, such as (from Michael Malone):
The bond market (even US-based) is primarily an international market. The rest of the world, especially Europe and Asia were already drinking champagne out of each other's slippers.
The question has 2 close votes, and 4 reopen votes, but is closed because one of the close votes comes from a moderator.
