Yes, it's been considered, but in my opinion no way has -24% GDP for the 2nd qtr. or 20% unemployment been priced in (others are saying -30% and 30% unemployment). Consensus numbers aren't forecasting those levels (yet), seems more likely that's what's being priced in than the worst current predictions.
Yes, the market looks ahead, but what exactly is priced in? You just wrote things like "terrible", "a ton", and "in the tank". There's a huge range of outcomes that would meet those definitions.
All we know is "some" bad news is priced in. There's really no way of knowing how much, or how bad it's going to actually get until after the fact.
