Study Insight: Fibonacci Numbers
by Howard Arrington
Leonardo de Pisa de Fibonacci (born around 1170 in Pisa, Italy) was a
mathematician who studied the Great Pyramid at Giza and discovered a number
series which we now call Fibonacci numbers. The number in the series is
the sum of the two previous numbers, and includes the set 1, 2, 3, 5, 8,
13, 21, 34, 55, 89, and 144. Dividing one number by the next after
the 8th sequence yields 0.618, which happens to be the
relationship of the height of the Great Pyramid to its base. Another
relationship is that the next number in the sequence is approximately 1.618
times the preceding number. These relationships are also a Fibonacci
number series: 0.382, 0.618, 1.000, 1.618, and 2.618, etc.
Fibonacci numbers are valuable because these numbers and relationships are
found everywhere in nature and in the markets. Frequently the
magnitude of a wave will have a Fibonacci relationship to the magnitude of
another wave structure. A wave's magnitude is determined by
measuring the price range from a significant top to a significant bottom.
The magnitude of a Trend wave might be 1.618 times the magnitude of the previous
Retracement wave. A corrective Retracement wave might be 0.618 times
the magnitude of the previous Trend.
Larry Pesavento shows in his book 'Profitable Patterns for Stock Trading'
that two additional ratios are frequently found in the markets.
These ratios are the square roots of the two primary Fibonacci
ratios. The square root of 0.618 = 0.786, and the
square root of 1.618 = 1.272. Larry uses these two
additional relationships, 0.786 and 1.272, because not all waves are a ratio of
0.618 and 1.618, or the other common ratios of 0.382, 0.500, and 2.618.
This example daily chart, Lucent Technologies Inc. (LU), is loaded with
Fibonacci relationships. The number of bars in each trend is shown
in a red box. Note that the number of bars in the initial trend and
its narrowing triangle consolidation sum to a Fibonacci number 55 = 8 + 8 + 5 +
8 + 5 + 8 + 8 + 5. Note the three wave bottoms that occur on
the 13th bar cycle from the prior bottom. Note the break away gap and the
21 bar run to the 1.618 Fibonacci extension level top.
Fibonacci ratios are easily applied to a chart using the Fibonacci Levels
tool in Ensign Windows. When you click on the Fibonacci
Levels button, the cursor will change to a pencil while in the draw
mode. A start and end point are necessary to draw Fibonacci Levels on a
chart. The distance between the start and end points is divided into
Fibonacci Levels which suggest possible support and resistance
points. To draw Fibonacci Levels on a chart move the cursor on the
chart to the starting point. The starting point is generally an important
high or low on the chart. Click the left mouse button down and drag the
mouse to the ending point, and release the mouse button. The ending point
is usually the end of an important trend or correction following the starting
point. Watch for the completion of a trend or correction at
a Fibonacci Level.
After drawing Fibonacci lines on a chart, click the right mouse button to
display the tool's properties window. The properties window is used to
change the levels, color, style, and defaults. A check box list of common
ratios is provided so that specific levels can be displayed or
hidden. The list includes the levels 0.786 and 1.272 that are the
focus of this month's study insight.

Article: Do Your Own Thinking
by Howard Arrington
Perhaps it is just an inherent human trait, but it never ceases to amaze me
the eagerness with which we want to embrace someone else's opinion. What
worries me is when traders don't think for themselves and place too much trust
in supposed 'experts'. That characteristic is even manifest by some
who subscribed to this newsletter hoping it would tell them what to buy or
sell. This newsletter won't do that. Instead it will try to teach
you to think, and give you tools and insight to help you do your own technical
analysis.
One can find on the Internet countless web sites offering advice,
newsletters, and stock picks. I raise a warning voice that traders should
not be so eager to embrace the information they peddle. I offer the
following look behind the smoke screen.
Many of the newsletters which offer daily picks, or hot-stocks to watch, fall
in the category which I call 'pump and dump' services. They artificially
manipulate stock prices for the benefit of the owners of the service. Some
of the picked stocks pay the newsletter or brokerage for the
promotion. Several years ago my broker would call with
suggested stocks to buy. I remember investing in Ramada Inns around $11 on
the broker's recommendation. His firm's research department had
issued a buy recommendation for Ramada. The stock ended up
being near its peak when I bought, and I eventually exited around
$7. Where was the broker during the decline? It sure
felt like I had been a victim of a 'pump and dump' promotion so my broker's firm
could unload Ramada stock, or he could turn a commission.
One of the stock-pick web sites I visited bragged that 83% of their picks hit
their suggested target price. I looked at their stock picks for the month
of December, and their table showed an impressive 20 out of 20 picks with a
positive value in the column labeled 'The Point Move It Made So
Far'. So, I looked at daily charts for each of their 20 stock picks
for December, and marked the price and the day of the suggested
pick. In so doing, I then saw through the smoke screen and got an
immediate distaste in my mouth for this stock-pick service. Look at
the following example that was their stock pick on 12-02-1999 at a price of
$18 1/4.
The following irritates me. First of all, this service says their
entry price is $18 1/4. This is the closing price on December 1st and
is pointed to with a red arrow. The stock pick was supposedly in an
e-mail issued on December 2nd prior to the market opening. If one
acted promptly, one might have bought the December 2nd open, but that is at a
higher price than the $18 1/4 they imply their subscribers bought at based on
their pick recommendation.
The real irritation is that they say this stock has made a $2 7/16 move so
far. When you study the chart, $2 7/16 is the difference between the
pick price of $18 1/4 and the highest high following the pick, which just
happens to be on December 2nd, the day of the pick. One would have
had to buy the previous day's close (impossible to do on December 2nd), and
sell at the highest high since then in order to realize the results implied by
this service. Come on people, give me a break. That
isn't going to happen. The implied 13% gain on this recommendation
is in reality probably a 30% loss. In all fairness, some of their
December picks have good gains after 4 to 8 weeks. What I am trying
to illustrate is that there is no substitute for doing your own thinking.
A second Internet stock-pick service I found, on the surface looked
exciting. This service evaluates 7,000 stocks each day and rank orders
them according to scores given for value, safety, and timing. To
monitor their stock picks, I entered their top 50 buy recommendations in a paper
trading account and used the closing price on January 25th as the entry
price. I dollar balanced the portfolio to invest $5000 to $6000 in
each stock. Was it just my 'bad luck' to start this exercise before
the DOW had a down week because of fear interest rates would rise?
Anyway, one week later the account was down 4.7%. But, during the
same time period, the DOW fell 2.6%. So, what gives? One would not
expect a list of BUY recommendations to crash faster than the DOW. In
fairness to this stock-pick service, they expect you to invest for the long
haul, and my critique of one week's setback is probably unfair.
Whether I am right or wrong in my assessment, or whether either of these
stock-pick services are worth the monthly fee they charge is not the
issue. What I am trying to do is to get you to think. Be
suspicious of stock-pick recommendations. Do your own analysis and
thinking. The greatest value I personally find in these stock-pick
services is it causes me to look at charts I otherwise would not have
examined. Occasionally, I find a recommended stock with a chart
formation that is attractive to me. Usually the biggest problem is
that by the time the stock appears on a recommendation list, the move I am
interested in is already history, and the chart is about to enter a
consolidation or correction wave.
Trader Profile: Allan Cook
ES: How long have you been trading, and what software do you use?
AC: I have been trading for more than 20 years. Years ago
when I was a large potato farmer, I traded Ag products during the winter
months. Now that I no longer have the farm, I am a full-time S&P
day trader. I have used Ensign Software programs since 1984.
ES: Which markets do you trade?
AC: I day trade just the S&P. 4 or 5 times a year
I might make a position trade in an Ag market. I would consider
positions in wheat, soybeans, cotton, sugar, heating oil, orange juice, US
bonds, live cattle, feeder cattle, live hogs, and pork bellies.
ES: What chart time-frames do you use?
AC: I watch a 3-minute chart and a daily chart for the S&P. I
don't look at anything else.
ES: What studies and tools do you use?
AC: None. I know you didn't want to hear that answer.
I pay attention to the bar formations on the 3-minute chart, and have developed
a sense or gut feel of how the market will behave. Yesterday was a
huge down day, and my gut feel a couple hours into today's trading was that the
bottom for today had been put in, and a sizable rally of 2000 to 3000 points
would occur before the close. I watch for support and resistance
levels and try to safely enter the market in the direction of the trend.
ES: How frequently do you trade?
AC: I trade 4 to 10 times a week. I am patient and wait for the
market to establish a trend. If the trend is up, I try to board the trend
using stops above resistance, or buy a setback. When the trend is
down, I will sell short using stops below support, or sell a rally.
But my trading is always in the direction of the trend. I never keep an
S&P position overnight.
ES: What kind of market do you look for?
AC: One or two days a week, the market fits my style. I stand
aside in fast markets because they can't guarantee fills and it is hard to know
if one is in or out of a fast market. Presently, these dynamic
markets are historic in their volatility. Markets like these have
never existed before, so I don't think there is a system out there that has the
experience to deal with today's markets. Even prior experience may not be
sufficient. I am constantly learning and adapting to the market as it
evolves.
ES: Since you don't use any of Ensign 6's studies or draw tools, what
do you look for in a chart?
AC: I watch price congestion levels, flags, pennants, breakouts and
retracements. I watch highs and lows, where the market closed the day
before and where it opened today. I wait for the market to establish
a trend and try to board using stops, or buy setbacks and sell rallies.
ES: What about risk management?
AC: When I place an order, my broker sends the order to the floor, and
then while the broker is still on the phone, I place a protective
stop. I never hang up with my broker without a stop in place.
Years ago there was a time when my broker's phone quit working, and there have
been times when a news event moved the market and one won't know about it
in time. For example, I was long the S&P the day the Challenger
exploded. I always place a protective stop while I am on the phone
with my broker. Then I am not in a panic if the market turns on me and
does something unexpected.
ES: What do you look for in a broker?
AC: The primary factor I need is best execution. That is
more important to me than the commission. The way I trade, I am
often in the market for only 10 to 15 minutes. My broker has a flash line
to the floor. I basically quit trading the Ag products because their
opportunities come only 4 to 5 times a year. But with the S&P's
volatility, there is opportunity every day. For my style of day
trading, I need quick execution.
ES: What is the ideal trade for you?
AC: The perfect trade is a small move with a large position in a highly
predictable formation. The money I take out of the market is a small
move in a short period of time, but with a large position. (ES:
AC gave more details but wanted the specifics withheld.) I really
don't like to suffer a lot. I am quick to be in and out of the
market. If the market does not do what I expect immediately, then I get
out of the trade.
ES: What advice would you share with the readers of the newsletter?
AC: Don't trade bigger positions than you are ready for. You need
to get your trading style worked out first. Too often traders have a few
successes, and then get their head handed to them on a plate. I work very
hard at not having any preconceived ideas about where the market will go.
Last of all, you have to do the work yourself. I remember years ago being
in a pork belly spread at my broker's advice before a report. The broker
said the spread was a safe way to play the report. The day of the
report, each leg of the spread went limit against me. If you want
advice from a broker, you should consider why he is a broker instead of a
trader. You just have to do your own work. Trading today's markets
is a technologically based art.
