What will actually happen is that frauds and poorly run companies will opt for the 6 month schedule while well run ones will keep the 3 month.
To your point that "executives should be tracking performance daily", there's an argument that all that data should be publicly released daily. It would make it nearly impossible to hide mismanagement and actually remove most of the human overhead since it would be impossible to spin bad data on a daily basis.
This is not how corporate fraud usually happens. You don't tamper with the quarterly report, especially since it gets audited. You tamper with the input data close to the source. For example, you record revenue that hasn't happened yet or you delay the recording of losses.
IMO, it would be ok if it was not unconditional.
If you have been public for >N years, and have had >X "clean" quarterly reports, no trouble with the SEC, etc, then sure, back off to 6mo (or even yearly, if your shareholders are ok with that).
But if you have an audit problem, violate SEC rules, get any kind of conviction, hell, even an inditement, then back to quarterly until you clean it up.
Releasing data at regular intervals gives people time to review the data, identify mistakes and rectify them. Releasing financial data daily, you are much more likely to release incorrect info and then have to go back and correct it.
For certain types of firms, daily revenue figures are likely to reveal individual deals. Many B2B firms have a modest number of high value deals, a daily data feed might show $0 revenue one day $1.374 million the next, which is more likely a single deal of that size than two or more smaller deals-and that would reveal a lot to competitors-especially if those competitors are in other jurisdictions which haven’t mandated this form of extreme transparency
