I’m a financial idiot – help me out here! Please!

I really don’t get it.

Two days ago we had a budget that will do nothing for this country.

Then, today, we hear that over the first three months of this year, the economy shrank by 1.9% – the biggest  three month decline since 1979.

However, the FTSE had a pretty good day today – up 3.43% and keeping gains that it made during the day which it normally doesn’t seem to do  – and the £ held up pretty well against the $ and the €, finshing about the same as it started today.

Why hasn’t every indicator that we’re in the shit fallen through the floor?

What’s going on?
