Technical Analysis Part
One
Technical analysis is the art and science of examining stock
chart data and predicting future moves on the stock market.
Investors who use this style of analysis are often unconcerned
about the nature or value of the companies they trade stocks
in. Their holdings are usually short-term – once their
projected profit is reached they drop the stock.
The basis for technical analysis is the belief that stock
prices move in predictable patterns. All the factors that
influence price movement – company performance, the general
state of the economy, natural disasters – are supposedly
reflected in the stock market with great efficiency. This
efficiency, coupled with historical trends produces movements
that can be analyzed and applied to future stock market
movements.
Technical analysis is not intended for long-term investments
because fundamental information concerning a company's
potential for growth is not taken into account. Trades must be
entered and exited at precise times, so technical analysts need
to spend a great deal of time watching market movements.
Investors can take advantage of both upswings and downswings in
price by going either long or short. Stop-loss orders limit
losses in the event that the market does not move as
expected.
There are many tools available to the technical analyst.
Literally hundreds of stock patterns have been developed over
time. Most of them, however, rely on the basic concepts of
'support' and 'resistance'. Support is the level that downward
prices are expected to rise from, and Resistance is the level
that upward prices are expected to reach before falling again.
In other words, prices tend to bounce once they have hit
support or resistance levels.
Charts
Technical analysis relies heavily on charts for tracking market
movements. Bar charts are the most commonly used. They consist
of vertical bars representing a particular time period –
weekly, daily, hourly, or even by the minute. The top of each
bar shows the highest price for the period, the bottom is the
lowest price, and the small bar to the right is the opening
price and the small bar to the left is the closing price. A
great deal of information can be seen in glancing at bar
charts. Long bars indicate a large price spread and the
position of the side bars shows whether the price rose or
dropped and also the spread between opening and closing
prices.
A variation on the bar chart is the candlestick chart. These
charts use solid bodies to indicate the variation between
opening and closing prices and the lines (shadows) that extend
above and below the body indicate the highest and lowest prices
respectively. Candlestick bodies are colored black or red if
the closing price was lower than the previous period or white
or green if the price closed higher. Candlesticks form various
shapes that can indicate market movement. A green body with
short shadows is bullish – the stock opened near its low and
closed near its high. Conversely, a red body with short shadows
is bearish – the stock opened near the high and closed near the
low. These are only two of the more than 20 patterns that can
be formed by candlesticks.
