July 5th, 2008Basic technical analysis – the moving average
There are two types of traders – fundamentalists and market technicians. The fundamentalists don’t concentrate on dissecting the numbers – earnings, cash flow, balance sheet, future profit projections – to come up with what they perceive to be the value of a company. When the stock trades lower then their perceived value, they buy shares.
A market technician concentrates on price and volume pattern, and historical prices to determine when to buy and sell. This is not to say they don’t care about the fundamentals. They just take a leap of faith that the fundamentals have already been baked in by everyone else to come up with the range of market prices. And they also take extra caution during times when the fundamentals can change everything else – earnings season.
So what is technical analysis? It’s a study of the statistics generated by market activity – mainly past price and volume action. And it’s the extrapolation of those studies to make a determination of where the market is going next. There are thousands of indicators and study sets that a market technician uses, but they key is not to use all of them at the same time! In fact, the best approach I’ve found is to really narrow the field to just a few basic studies.
The examples below will use Boeing (BA) as an example only. And to ensure the most timely data, I will link to the Yahoo Finance pages so you can see the charts yourself.
Support and Resistance – Stocks will often stay within channels and bounce between support and resistance lines. When the price of a stock goes to low, the value investors are jumping in with their buy orders. The price point at which heavy buy activity starts is the support line. It is the low points in a chart at which the stock price stops going lower, and reverses direction to proceed higher. The resistance level is the exact opposite and it is the point at which people get nervous and stop buying because the perceived price is to high. Support and resistance levels are easier to see on range charts (bar or candle) versus line charts.
Moving Average – a moving average is a method to smooth out a jagged price chart, where each point on the moving average line is an average price over a given period. A 20 day moving average would utilize 20 days of information (today’s price plus the previous 19) for every point on the graph. Take a look at the Boeing moving average to see for yourself. The moving average is one of the simplest technical indicators. As prices broach the moving average line, many people believe it will continue in the same direction for a long enough time to yield a profit.
