Technical Analysis Part Two – Indicators and
Patterns
When glancing at charts the untrained eye may simply see random
movements from one day to the next. Trained analysts, however,
see patterns that are used to predict future movements of stock
prices. There are hundreds of different indicators and patterns
that can be applied. There is no one single reliable indicator,
but when taken into consideration with others, investors can be
quite successful in predicting price movements.
Patterns
One of the most popular patterns is Cup and Handle. Prices
start out relatively high then dip and come back up (the cup).
They finally level out for a period (handle) before making a
breakout – a sudden rise in price. Investors who buy on the
handle can make good profits.
Another popular pattern is Head and Shoulders. This is formed
by a peak (first shoulder) followed by a dip and then a higher
peak (the head) followed again by a dip and a rise (the second
shoulder). This is taken to be a bearish pattern with prices to
fall substantially after the second shoulder.
Indicators
Moving Average
The most popular indicator is the moving average. This shows
the average price over a period of time. For a 30 day moving
average you add the closing prices for each of the 30 days and
divide by 30. The most common averages are 20, 30, 50, 100, and
200 days. Longer time spans are less affected by daily price
fluctuations. A moving average is plotted as a line on a graph
of price changes. When prices fall below the moving average
they have a tendency to keep on falling. Conversely, when
prices rise above the moving average they tend to keep on
rising.
Relative Strength Index (RSI)
This indicator compares the number of days a stock finishes up
with the number of days it finishes down. It is calculated for
a certain time span – usually between 9 and 15 days. The
average number of up days is divided by the average number of
down days. This number is added to one and the result is used
to divide 100. This number is subtracted from 100. The RSI has
a range between 0 and 100. A RSI of 70 or above can indicate a
stock which is overbought and due for a fall in price. When the
RSI falls below 30 the stock may be oversold and is a good time
to buy. These numbers are not absolute – they can vary
depending on whether the market is bullish or bearish. RSI
charted over longer periods tend to show less extremes of
movement. Looking at historical charts over a period of a year
or so can give a good indicator of how a stock price moves in
relation to its RSI.
Money Flow Index (MFI)
The RSI is calculated by following stock prices, but the Money
Flow Index (MFI) takes into account the number of shares traded
as well as the price. The range is from 0 to 100 and just like
the RSI, an MFI of 70 is an indicator to sell and an MFI of 30
is an indicator to buy. Also like the RSI, when charted over
longer periods of time the MFI can be more accurate as an
indicator.
Bollinger Bands
This indicator is plotted as a grouping of 3 lines. The upper
and lower lines are plotted according to market volatility.
When the market is volatile the space between these lines
widens and during times of less volatility the lines come
closer together. The middle line is the simple moving average
between the two outer lines (bands). As prices move closer to
the lower band the stronger the indication is that the stock is
oversold – the price should soon rise. As prices rise to the
higher band the stock becomes more overbought meaning prices
should fall. Bollinger bands are often used by investors to
confirm other indicators. The wise technical analyst will
always use a number of indicators before making a decision to
trade a particular stock.
