I do a personal yearly forecast every year (at least I have for the last 5 years). I've never published before though, thought I might here anyway see if it holds up.

I put quite a lot of work into these every year (despite them looking so short). Although only people I know have got to see them before. Its based on a bit of pattern matching and long range models mostly. I don't expect it to be that accurate; mostly just for fun.
