Technical Analysis
What is Technical Analysis?
Advertisement |
Technical Analysis is the forecasting of future financial price movements based on an examination of past price movements. Like weather forecasting, technical analysis does not result in absolute predictions about the future. Instead, technical analysis can help investors anticipate what is "likely" to happen to prices over time. Technical analysis uses a wide variety of charts that show price over time.
Technical analysis is applicable to stocks, indices, commodities, futures or any tradable instrument where the price is influenced by the forces of supply and demand. Price refers to any combination of the open, high, low, or close for a given security over a specific time frame. The time frame can be based on intraday (1-minute, 5-minutes, 10-minutes, 15-minutes, 30-minutes or hourly), daily, weekly or monthly price data and last a few hours or many years. In addition, some technical analysts include volume or open interest figures with their study of price action.
The Basis of Technical Analysis
At the turn of the century, the Dow Theory
laid the foundations for what was later to become modern technical
analysis. Dow Theory was not presented as one complete amalgamation, but
rather pieced together from the writings of Charles Dow over several
years. Of the many theorems put forth by Dow, three stand out:
- Price Discounts Everything
- Price Movements Are Not Totally Random
- What Is More Important than Why
Price Discounts Everything
This theorem is similar to the strong and semi-strong forms of market
efficiency. Technical analysts believe that the current price fully
reflects all information. Because all information is already reflected
in the price, it represents the fair value, and should form the basis
for analysis. After all, the market price reflects the sum knowledge of
all participants, including traders, investors, portfolio managers,
buy-side analysts, sell-side analysts, market strategist, technical
analysts, fundamental analysts and many others. It would be folly to
disagree with the price set by such an impressive array of people with
impeccable credentials. Technical analysis utilizes the information
captured by the price to interpret what the market is saying with the
purpose of forming a view on the future.
Prices Movements are not Totally Random
Most technicians agree that prices trend. However, most technicians
also acknowledge that there are periods when prices do not trend. If
prices were always random, it would be extremely difficult to make money
using technical analysis. In his book, Schwager on Futures: Technical Analysis, Jack Schwager states:
"One way of viewing it is that markets may witness extended periods of random fluctuation, interspersed with shorter periods of nonrandom behavior. The goal of the chartist is to identify those periods (i.e. major trends)."
A technician believes that it is possible to identify a trend, invest or trade based on the trend and make money as the trend unfolds. Because technical analysis can be applied to many different time frames, it is possible to spot both short-term and long-term trends. The IBM chart illustrates Schwager's view on the nature of the trend. The broad trend is up, but it is also interspersed with trading ranges. In between the trading ranges are smaller uptrends within the larger uptrend. The uptrend is renewed when the stock breaks above the trading range. A downtrend begins when the stock breaks below the low of the previous trading range.

"What" is More Important than "Why"
In his book, The Psychology of Technical Analysis, Tony
Plummer paraphrases Oscar Wilde by stating, "A technical analyst knows
the price of everything, but the value of nothing". Technicians, as
technical analysts are called, are only concerned with two things:

- What is the current price?
- What is the history of the price movement?
