Just my thoughts. Bull then Bear over the next two years. Extremely difficult to estimate the top and the bottoms. But the Fib people are saying anywhere from 2500 to 3600 for a high, and then a low of equal size, or not. A lot depends on earnings, international growth models (EU and China), tax policies, energy costs and geo-politicals (wars). Some of these variables are impossible to predict. But I think higher interest rates are likely. And energy will get cheaper. And there will be wars. Too many random variables to predict highs and lows 2-5 years in the future. You will always be wrong.
