@ericries says public companies that report quarterly tend to be 5% less valuable than those that report semiannually, based on data from other countries.
"It's not because the effort to do a quarterly report is expensive (although it is expensive and annoying). Rather, they start to run the company for the quarterly report."
"So companies no longer make products. They start to view the quarterly report as the product. Which means they're basically meme factories — 'What do I have to do to generate the report that will get me what I want?'"
"If you look at other countries as natural experiments, where certain countries have switched from semiannual to quarterly reporting, or vice versa, and they happen to do it in such a way that not every company changed at the same time, and it was random who did which. We actually know the valuation consequences of quarterly reporting. It's roughly a 5% loss of total equity value."
"Companies are 5% less valuable when they report quarterly, vs. semiannual."
"The academic research on this is pretty good. And the magnitude of the cost — we're talking about so many billions of dollars of lost value."
