Market Predictions for 2012 based on Trends

Last week, I reported Bloomberg Consensus of Predictions for Year-End 2012 in Where are Markets Headed for 2012 ?

That was their average forecast:

1. S&P 500: 1,428 vs Current: 1,229
2. 10-year Treasury yield: 2.86% vs Current: 2.14%
3. Inflation rate: 2.05% vs Current: 3.9%
4. Unemployment rate: 8.7% vs Current: 9.1%
5. GDP growth in fourth quarter: 2.5% vs Second quarter, 2011: 1.3%
6. Gold price per ounce on Sept. 30, 2012: $1,835 vs Current: $1,704
7. Value of euro: $1.40 vs Current: $1.39
8. S&P/Case-Shiller 20-City Composite Home Price Index: 136.6 vs Current: 142.8
9. Barrel of oil: $95 vs Current: $92.58

Today, I'm going to do forecast for the same metrics in a "dumb" way by simply checking the trends on charts and give an estimate for each items and we'll see how it fares end of December 2012:

1. S&P 500: 1000
2. 10-Year Treasury yields: 2.5%
3. Inflation Rate: 2.5%
4. Unemployment Rate: 8.8%
5. GDP Growth Rate: 1%
6. Gold Price: 1850 USD
   
7. Euro: 1.37 US dollar
8. S&P Case-Shiller 20-City Composite Home Price Index: 135
9. Barrel of Oil (WTI): 125 US dollar

Sometimes I took the long term trend (e.g. 10 year on gold) and other times shorter trends (e.g end of 2008 to now for oil).
