All Time Highs just AFTER the US has started a major recession?

I asked my buddies on the stock market forum I frequent, whether they knew of any other examples where the markets set new ATH just AFTER the US had started a major recession. They said they didn't know of one. This is definitely the biggest bubble EVER. 

It is quite likely the US entered recession at some point in May. 
It won't be reported as such for quite a while yet. 
Probably not until the US Q3 GDP numbers come out in October. 

Maybe not even then. 
The way that US GDP is calculated is being amended from July. 
The changes are expected to add around 3% to reported GDP. (They have no basis or foundation in fact, most of it is double counting.)
