· Price Discounts Everything
· Price Movements Are Not Totally Random
· "What" Is More Important than "Why"
One very popular form of technical analysis until the
mid-1960s was "tape reading". It consisted in reading the
market information as price, volume, orders size, speed, conditions, bids for
buying and selling, etc.; printed in a paper strip which ran through a machine
called a stock ticker.
Technical analysts do not attempt to measure a security's
intrinsic value, but instead use charts and other tools to identify patterns
that can suggest future performance. Technical
analysts consider the market to be 80% psychological and 20% logical.
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.
Since a market's price reflects all relevant information, their analysis looks at the history of a security's trading pattern rather than external drivers such as economic, fundamental and news events. Therefore, price action would also tend to repeat itself due many investors collectively tend toward patterned behavior – hence technicians' focus on identifiable trends and conditions.
So based on the premise that all relevant information is
already reflected by prices, technical analysts believe it is important to
understand what investors think of that information, known and perceived. Technical analysts examine what investors
fear or think about those developments and whether or not investors have the
wherewithal to back up their opinions; these two concepts are called psych
(psychology) and supply/demand. Technicians employ many techniques, one of
which is the use of charts. Using charts, technical analysts seek to identify
price patterns and market trends in financial markets and attempt to exploit those patterns. Technicians use various
methods and tools, the study of price charts is but one.
Many technicians employ a top-down approach that begins with broad-based macro analysis. The larger parts are then broken down to base the final step on a more focused/micro perspective. Such an analysis might involve three steps:
-
Broad market analysis through the major indices such as the S&P 500, Dow Industrials, NASDAQ and NYSE Composite.
- Sector analysis to identify the strongest and weakest groups within the broader market.
- Individual stock analysis to identify the strongest and weakest stocks within select groups.
The beauty of technical analysis lies in its versatility. Because the principles of technical analysis are universally applicable, each of the analysis steps above can be performed using the same theoretical background. You don't need an economics degree to analyze a market index chart. You don't need to be a CPA to analyze a stock chart. Charts are charts. It does not matter if the time frame is 2 days or 2 years. It does not matter if it is a stock, market index or commodity. The technical principles of support, resistance, trend, trading range and other aspects can be applied to any chart.
Technical analysts believe that
investors collectively repeat the behavior of the investors that preceded them.
To a technician, the emotions in the market may be irrational, but they exist.
Because investor behavior repeats itself so often, technicians believe that
recognizable (and predictable) price patterns will develop on a chart.
Technicians using charts search for archetypal price
chart patterns, such as the well-known head and
shoulders or double top/bottom
reversal patterns, study technical indicators,
moving averages, and look for forms such as lines
of support, resistance, channels, and more obscure formations such as flags, pennants,
balance days and cup and handle
patterns.
Technical analysts also widely use market indicators of
many sorts, some of which are mathematical transformations of price, often
including up and down volume, advance/decline data and other inputs. These
indicators are used to help assess whether an asset is trending, and if it is,
the probability of its direction and of continuation. Technicians also look for
relationships between price/volume indices and market indicators. Examples include
the relative strength
index, and MACD. Other avenues of study include correlations
between changes in Options (implied volatility)
and put/call ratios with price. Also important are sentiment indicators such as
Put/Call ratios, bull/bear ratios, short interest, Implied Volatility, etc.
There are many techniques in technical analysis.
Adherents of different techniques (for example, candlestick charting, Dow Theory, and Elliott wave theory)
may ignore the other approaches, yet many traders combine elements from more
than one technique. Some technical analysts use subjective judgment to decide
which pattern(s) a particular instrument reflects at a given time and what the
interpretation of that pattern should be. Others employ a strictly mechanical
or systematic approach to pattern identification and interpretation.
Technical analysis employs models and trading rules based
on price and volume transformations, such as the relative strength
index, moving averages, regressions,
inter-market and intra-market price correlations, business cycles, stock market cycles
or, classically, through recognition of chart patterns.
Charting Terms
and Indicators
Concepts:
- Resistance – a price level that may prompt a net increase of selling activity
- Support – a price level that may prompt a net increase of buying activity
- Breakout – the concept whereby prices forcefully penetrate an area of prior support or resistance, usually, but not always, accompanied by an increase in volume.
- Trending – the phenomenon by which price
movement tends to persist in one direction for an extended period of time
- Average true range
– averaged daily trading range, adjusted for price gaps
- Chart pattern – distinctive pattern created
by the movement of security prices on a chart
- Dead cat bounce – the phenomenon whereby a
spectacular decline in the price of a stock is immediately followed by a
moderate and temporary rise before resuming its downward movement
- Elliott wave
principle and the golden ratio to calculate successive price
movements and retracements
- Fibonacci ratios – used as a guide to
determine support and resistance
- Momentum
– the rate of price change
- Point and figure
analysis – A priced-based analytical approach employing
numerical filters which may incorporate time references, though ignores
time entirely in its construction.
- Cycles –
time targets for potential change in price action (price only moves up,
down, or sideways)
Types of charts:
- Open-high-low-close
chart – OHLC charts, also known as bar charts, plot the span
between the high and low prices of a trading period as a vertical line
segment at the trading time, and the open and close prices with horizontal
tick marks on the range line, usually a tick to the left for the open
price and a tick to the right for the closing price.
- Candlestick chart
– Of Japanese origin and similar to OHLC, candlesticks widen and fill the
interval between the open and close prices to emphasize the open/close
relationship. In the West, often black or red candle bodies represent a
close lower than the open, while white, green or blue candles represent a
close higher than the open price.
- Line chart – Connects the closing price
values with line segments.
- Point and figure
chart – a chart type employing numerical filters with only
passing references to time, and which ignores time entirely in its
construction.
Overlays:
Overlays are generally superimposed
over the main price chart.
- Resistance
– a price level that may act as a ceiling above price
- Support
– a price level that may act as a floor below price
- Trend
line – a sloping line described by at least two peaks or two
troughs
- Channel – a pair of parallel trend lines
- Moving average – the last n-bars of price
divided by "n" -- where "n" is the number of bars
specified by the length of the average. A moving average can be thought of
as a kind of dynamic trend-line.
- Bollinger bands – a range of price
volatility
- Parabolic SAR – Wilder's trailing stop based on prices tending to stay within a parabolic curve during a strong trend
- Pivot point – derived by calculating the
numerical average of a particular currency's or stock's high, low and
closing prices
- Ichimoku kinko hyo – a moving average-based
system that factors in time and the average point between a candle's high
and low
Price-based
indicators:
These indicators are generally shown
below or above the main price chart.
- Average
directional index – a widely used indicator of trend strength
- Commodity Channel
