The decline in employee option exercise... is that the canary in the mine? If the team itself is saying less and less that their company's equity is worth taking a risk on -- and they are in a good position to be optimistic, rightly or wrong -- then that's a pretty bearish signal.

Of course there are other pressures on peoples' personal finances that makes money dearer... but still.

Or perhaps with layoffs there is just a lot of people who could be exercising vested options, but won't because (1) they no longer work there and won't be able to contribute or have an insider advantage, and/or (2) they now don't have a job so won't risk the capital in buying out their options.
