FTSE 100 - sliding?

At lunchtime, the FTSE 100 UK share index is down 0.38%. It was higher, but still negative on the day.

We should expect it to gradually slide in the months ahead as investors are still nervous about Greece, the EU, China and the world economy at large. It always bounces back, although this could take years. My expectations this year? I think it will fall to around 5000 then bounce back to 6500. Of course I am only guessing and it could end up between 4000 and 7000.
