Forecasting
Introduction
Forecasting is predicting the future. There is a risk that the forecast may turn out to be wrong. Examples of forecast are:-
- Forecasting is a very important part of managing an economy e.g. interest rates are set by the Bank of England on historical real inflation data and on forecast inflation data (food prices up, oil prices up, taxes also up etc).
- In addition, forecasting is used by Estate Agents e.g if house prices crash in 2008 then they will probably say "We forecast 2009 will be a year of booming house prices"! See "House Price Predictions" on the home page of House Price Crash.com
- Finally, forecasting is also used by the weathermen to predict tomorrow's weather, and we all know how accurate their forecasts are don't we!
Forecasting has been around for hundreds of years. We have all been to a fairground where Gypsy Rose (who for a sliver of silver) peered in to the crystal ball and told us our futures!
Quotes:
- "The line separating investment and speculation, which is never bright and clear, becomes blurred still further when most market participants have recently enjoyed triumphs. Nothing sedates rationality like large doses of effortless money. After a heady experience of that kind, normally sensible people drift into behavior akin to that of Cinderella at the ball. They know that overstaying the festivities -- that is, continuing to speculate in companies that have gigantic valuations relative to the cash they are likely to generate in the future -- will eventually bring on pumpkins and mice. But they nevertheless hate to miss a single minute of what is one helluva party. Therefore, the giddy participants all plan to leave just seconds before midnight. There’s a problem, though: They are dancing in a room in which the clocks have no hands" - Warren Buffett
- "Long ago, Sir Isaac Newton gave us three laws of motion, which were the work of genius. But Sir Isaac's talents didn't extend to investing: He lost a bundle in the South Sea Bubble, explaining later, 'I can calculate the movement of the stars, but not the madness of men.' If he had not been traumatized by this loss, Sir Isaac might well have gone on to discover the Fourth Law of Motion: For investors as a whole, returns decrease as motion increases". - Warren Buffett
