however the bigger issue here - is this is a ruse - there is a reason quarterly reporting brought transparency to companies - now they can easily hide nasty things.
you as an employee with stock options - yeah those are close to worthless since the price hit you can take can vary a lot.
For 6 months instead of 3. One could argue the need to show quarterly growth forces companies to do nastier things. Long term thinking is definitely needed these days when all companies are only focusing on short term gains.
Before 1970, the reporting was twice a year and in the first half of the twentieth century it was once a year.
I think a small subset of people might adopt a short-term approach to equity ownership. I think a much larger subset would simply be selling to access the money they rightfully earned or to diversify their holdings instead of having the bulk of their stock portfolio in a single company.
What if someone froze half of your paycheck and said you can't touch it except for the two months out of the year that they say you can?
