The UK went back and forth on it:

> Beginning in 2007, UK public companies were required to issue quarterly, rather than semiannual, financial reports. But the UK removed this quarterly reporting requirement in 2014. We studied the effects of these regulatory changes on UK public companies and found that the frequency of financial reports had no material impact on levels of corporate investment. However, mandatory quarterly reporting was associated with an increase in analyst coverage and an improvement in the accuracy of analyst earnings forecasts.

So it seems that if you want more accurate analysis for investors (and current stock holders), more frequent is better.

This is a really key point - it’s already working fine elsewhere.
