Stock-Picking Strategies: Technical Analysis

Technical analysis is the polar opposite of fundamental analysis, which is the basis of every method explored so far in this tutorial. Technical analysts, or technicians, select stocks by analyzing statistics generated by past market activity, prices and volumes. Sometimes also known as chartists, technical analysts look at the past charts of prices and different indicators to make inferences about the future movement of a stock's price.

Philosophy of Technical Analysis
In his book, "Charting Made Easy", technical analysis guru John Murphy introduces readers to the study of technical analysis, explaining its basic premises and tools. Here he explains the underlying theories of technical analysis:

"Chart analysis (also called technical analysis) is the study of market action, using price charts, to forecast future price direction. The cornerstone of the technical philosophy is the belief that all factors that influence market price - fundamental information, political events, natural disasters, and psychological factors - are quickly discounted in market activity. In other words, the impact of these external factors will quickly show up in some form of price movement, either up or down."

The most important assumptions that all technical analysis techniques are based upon can be summarized as follows:

1. Prices already reflect, or discount, relevant information. In other words, markets are efficient.
2. Prices move in trends.
3. History repeats itself.

What Technical Analysts Don't Care About
Pure technical analysts couldn't care less about the elusive intrinsic value of a company or any other factors that preoccupy fundamental analysts, such as management, business models or competition. Technicians are concerned with the trends implied by past data, charts and indicators, and they often make a lot of money trading companies they know almost nothing about.

Is Technical Analysis a Long-Term Strategy?
The answer to the question above is no. Definitely not, Technical analysts are usually very active in their trades, holding positions for short periods in order to capitalize on fluctuations in price, whether up or down. A technical analyst may go short or long on a stock, depending on what direction the data is saying the price will move.

If a stock does not perform the way a technician thought it would, he or she wastes little time deciding whether to exit his or her position, using stop-loss orders to mitigate losses. Whereas a value investor must exercise a lot of patience and wait for the market to correct its undervaluation of a company, the technician must possess a great deal of trading agility and know how to get in and out of positions with speed.


Support and Resistance
Among the most important concepts in technical analysis are support and resistance. These are the levels at which technicians expect a stock to start increasing after a decline (support), or to begin decreasing after an increase (resistance). Trades are generally entered around these important levels because they indicate the way in which a stock will bounce. They will enter into a long position if they feel a support level has been hit, or enter into a short position if they feel a resistance level has been struck.
