| Colin Email Questions:
( 11/28/04 ) Colin, Below are some comments regarding your questions. Also on my web page, you might check out the replies and info listed under the [FAQS] tab located at the top of the page on the navigation Bar. Hello Schippi: What a great website that you have developed! Now that I have discovered your website, I have several questions in regards to your indicators, regression tables and market analysis. Market Indicators: When comparing the number of highs to the number of lows, other than just the raw daily numbers, are you looking at weekly data and have you incorporated some type of moving average to signal a red light or green light? What is your criteria for this indicator to go from red to green and green to red? I will post a Yellow light when the number of Highs rapidly declines and a Red light when it falls beneath the number of Lows. Green light of course means the number of Highs exceeds the number of Lows and is moving Up. On the Summation Index, you have incorporated a 20 day exponential moving average. Is the red or green signal given when the index crosses below or above the 20 day ema and is there a weekly confirmation signal or is this a daily signal? Criteria? The daily classic Sumation Index URL for both the NYSE and the NASDAQ URL is posted on my web page and is provided by DecisionPoint.com. The Summation Index I put together by combining all 41 sectors is updated daily. I label an uptrend when the Index crosses it's 20 day EMA and is moving Up and a downtrend when it crosses below the 20 day EMA. On the McClellan Oscillator, again, is this a weekly signal and what is your timeframe for a confirming signal? In addition, what is your criteria to go from green to red and red to green? For the Oscillator the zero line is neutral, above it, I label it Green and below it I label it Red. Both the Oscillator and Summation Index are computed daily. Regression Table · How do you calculate your gain/risk factor? I have been using a 30 day factor based upon dividing the standard error of the regression into the 30 day relative strength. My object is to get a fund that is trending higher and following its 30 day regression as close as possible (numerator big, denominator small). This also includes forecasting a 30 day NAV that is positive. Again, you will find regression info under the [FAQS] tab. But basically I will perform a quadratic or cubic regression curve fit for each of the 41 sectors. The beginning and end-points of the sector data are smoothed when computing the Gain. (ie) The ordinate change over the specified interval. The residuals defined by the sector NAV data and the regression curve fit are formed. The standard deviation of these residuals, I define to be risk. General: You have chosen Rydex funds to “short” the market. Did you do a correlation analysis to pick these funds or what was your criteria for picking these funds? If you are trading from an IRA mutual fund from Fidelity, you not allowed you to short the market. Rydex was the first to provide a fund you could buy that was inversely correlated with the market. When my collection of indicators suggest a decline, I will first go to a market neutral position by balancing my long with short positions. After the market trend become clear I will keep whatever is profitable and sell the rest. Are there any Fidelity funds that you know of that you can utilize to “short” the market? Fidelity will not let you short any Fund from an IRA. Also it does not provide any inverse funds. Select Sector Charts: Is your select sector index a total of all 41 select fund nav’s? Also, your chart is showing percent change. How do you calculate this? All my charts are computed and posted in percent as this is the only way you can easily compare Sectors. The SelectSector Index is the daily average of all 41 sectors. Finally, what do the red and green lines indicate on your SSindex internal strength oscillator? The Green and Red lines are symmetrical. Green represents advancing strength and Red declining strength. I am assuming that your high tech index is constructed the same way as the select sector index. That is correct. I want to understand your thought process on what you have developed. We all can use some help in defining turning points in the market. I agree with your comment that it is not how much you make but how much you keep. Thanks for all of your help. Colin, Hope this helps. Schippi |

| Schippi Alert: (
10/26/04) Election Rally Starts Tomorrow. Hello. Today's web page update won't be completed for a few hours, but in crunching the numbers a result came up that I thought would be best passed along now, because of the large Hawaii time difference. The Hurst SelectSectors Index chart displays a surprise minimum, which implies a market rally. My take on this is that it's a contrived election rally and may be very short. If the overseas market and our market is Up at the open, I will purchase 200% long Rydex dynamic funds with the hope of grabbing some Christmas shopping dollars. Best Regards Schippi Ps The above is not a recommendation and is for information only. |

( 08/24/2004) Dear Mr. Schippi: It is really discouraging to see your entire charts. This is the time to get out of the stock markets all together and forget about it or is there still some hope to gain in the future? America is losing its grip as world power and losing its position as economic super power. Our standard of living will be going down as a result and there is no bright spot for those contemplating their retirement. Please comment whether equity market is going down the hill as the professor is predicting in the future. James, From the beginning of time Equity Markets have gone Up and Down, don't be discouraged rather learn how to defend yourself. First of all give thanks for the Internet, which puts the research of the whole world at your finger tips. You can profit when the Market declines. Consider Rydex inverse Funds ( www.rydexfunds.com ) or ProFunds ( www.profunds.com ). With these tools in your toolbox you can defend yourself no matter what the Market throws at you. About professor Sornette's prediction models, this is very high powered mathematics, but at best remains a prediction and is not necessarily what will be. Again if it were to occur the above methodology would be profitable. Best Regards Schippi |

Email Questions: 10/28/00Question: Do you have a spreadsheet, etc. that you use to perform your
analysis?
No, I have written all my programs/graphics in Matlab.
Question: Do you use hourly or end of day data?
The regression tables are computed using closing NAV.
Question: Have you ever determined your average yearly rate
of return using your method ?
No I have not. However the current market downturn,
has hit most sectors very hard. I am very pleased that
the number one selection, for the past several weeks,
Medical Delivery ( FSHCX ) has held up so well.
In my mind, I take this as an implicit verification of the
regression methodology used to calculate my Maximum
Gain per unit Risk tables.
Best Regards
Schippi
Subject: Select Hourly PricingI found your fidelity sector web site at http://www.geocities.com/schippi/
right around August 5, 2000. I found it very interesting and soon followed the link to obtain hourly pricing. I created a spreadsheet to compile the hourly pricing so that I could manipulate it as desired at my convenience.
After compiling the data from 8/7-17/2000, I found that the link accessed from your site or via bookmark
(http://personal300.fidelity.com/gen/prices/select.html) no longer supported viewing the hourly pricing either during the day or at the end of the day.
As I am writing this, I again tried accessing it through your web site and now find you have it available again through a new link
(http://activequote400.fidelity.com/nav/select.phtml).
Is this some special arrangement you have with Fidelity or can anyone create their own hourly import page from Fidelity or some other data source? I find that the hourly data accessed through my account at Fidelity is not generally up to the most recent hour, even when choosing the "real-time" option. I find it frustrating when I start tracking data and then find it to be no longer available. I track quite a lot of stocks the same way.
Thanks in advance. And I hope you keep up the great site!
Tom

First of all, I have no special arrangements with Fidelity.
Like you, I just invest in some of their funds.With regard to the URL’s to download Selects closing NAV,
their latest URL, complete with format changes in their download,
is available at:
http://activequote.fidelity.com/nav/select.csv
Their previous system ( URL ) was not reliable and had late
and missing data for about 6 months. During that time I complained
to everyone at Fidelity about it. It was a very Ugly battle. This URL
is definitely an improvement. However late or missing data are still
to be expected from time to time. This should not be too much of a
concern, as in my experience it’s better to trade the current trend and
not pay too much attention to the fluctuations in one day.Hope this helps

Anne wrote: (12/03/99)
Since you download these NAV's hourly
any chance of displaying daily candlesticks?
Hourly MA's or MACD's?
Thanks in advance
...................................................................................................
Hello Anne
With regard to candlesticks:
I post every hour-data-point. So all fund data is presented. Candlesticks, just exhibit Open/Close and High/Low and therefore provide less information. For hourly charts I fail to see how this is useful.For large time intervals, candlesticks are useful, as they compress data and still provide useful charts. These type of charts are readily available on the Web.
With regard to MA's or MACD's
This brings up an important philosophical question. Both MA's and MACD's are trend following procedures. The implicit question then arises as to what level of data granularity is required for these processes. My own experimentation using hourly data for these processes yielded nothing of additional value. Stated another way, if you continue to process finer data you reach a point where the data is dominated by noise and contributes nothing to the process itself.From a different perspective I do find the singularities ( in derivative) of the fund turning points to be significant. These are the chart-points where the fund trend abruptly changes from Up to Down or Down to Up. I think Wavlet theory also makes this same point.
Hope this helps, Have a Great Holiday!

I found your web site today via a reference in the latest issue
of the magazine "Technical Analysis of Stocks & Commodities".
I have been investing in ths Fidelity Select Group for the last several
months and found your site most interesting.One question, Why do you do this? How do you make any money? I did not see any advertising.
...................................................................................................Clyde
Glad you enjoyed my web page. It is free and I receive no income from it. Several of my friends wanted to know what I was doing in the market.
I refused to handle or give investment advice, but provided this webpage, so they and others would have my investment information .I provide this information in the hope that it will assist them in making their own investment decisions. I do not charge or advertise as I have more than enough money, (ie) This morning (9/27/99) I am Up over $50,000.
Good Luck with Your Investments

Hello:
Could you help me to understand this chart:
http://www.SelectSectors.com/goldind.htm
Gold Sensitive Indicators Chart
Gold(FSAGX), Prec-Met(FDPMX), CRB, XAU, TW-US$ and Comex-Gold
Thank you for any help, Frank
...................................................................................................
Frank, my read of the Gold Sensitive Indicators Chart as of 7/2/99 is as follows: The most prominent feature is the large head and shoulders top made by the XAU and the Gold sectors FSAGX and FDPMX and then the subsequent decline. It is also noted that the Comex-Gold steadily declined at this time. This large Decline was of course triggered by the Bank Of England statement to sell large quantities of Gold. Toward the end of the chart, we see the upward thrust of the XAU and the Gold sector funds. This is also in concert with bottoming and subsequent rise of Comex Gold. The fact that Gold is rallying while the trade weighted US dollar steadily rises, to me, Implies that there is real strength behind the current Gold rally and therefore I have purchased large amounts of both FSAGX and FDPMX. The CRB index is heavily weighted By agriculture products and does not contribute much to the picture but is included for completeness.
Please note that the above is nothing more then my private interpretation of this chart and is not an investment recommendation. It is up to each individual to evaluate the data and then take appropriate action.
Good Luck with your Investments!

From Carl F.
Please explain Regression.
...................................................................................................Carl
The hourly Select fund data is downloaded daily. In this manner the data represents discrete data functions. This data is processed to determine the "Best" performing fund. Here "Best" is taken to mean the fund that has the Maximum Uptrend coupled with the least amount NAV variation. Regression is the process of numerically determining the coefficients of a linear combination of base functions that represent or curvefit the daily discrete data.
The base functions selected can be "anything" (ie) Trig functions, Exponentials etc. However selecting polynomials is a manageable and effective choice.
This leads to a simple linear system of equations, other choices lead to nonlinear equations and iterative processes. Complexity but no gain in profit.
The criteria used to determine the polynomial coefficients is the standard minimization of the sum of the squared residuals between the discrete data and the polynomial being curvefit.
The regression tables rank the ratio of Gain per unit risk. Where risk is defined as the standard deviation of the residuals between the data and curvefited polynomial. The 30 day table yields the top fund for this time interval.
Similarly for the 60 and 90 day regression tables. Finally these overall results are combined to produce the best overall fund.
The important thing here is not the mathematics but how this might help you to invest. Keep in mind that this process is most useful when there is a strong and uniform trend in place. Severe market corrections, where we have a trend Up followed by a trend down, will render this approach almost to be meaningless.

From David B. M.
My guess is that you work for/with Fidelity Funds. Yes/No ?
...................................................................................................David
I have NO relationship whatsoever with Fidelity Investments.
However, I do invest in their Funds. I chose Fidelity because their Select
Funds act as a proxy for the Market, they alone have hourly pricing,
have a great telecommunication system and have always provided good service.

From David C.
Are the returns from the 30 day, greater or about the same,
as the 90 day regression table?
...................................................................................................David
My experience is that small time intervals, defining the data
you are processing, produces short lived trends. (ie) the hourly
chart breakout, can look dramatic, but it might only last a few days.
I use the 30 day regression table for two reasons.
(1) Often after a market correction, the regression table is not
well defined, as you have a leg down, followed by a leg up. In this
context, the 30 day table will produce better results because it
truncates more of the down leg.
(2) Sometimes, after a period of dormancy, a fund will break out.
The 30 day regression table will pick this up first.
Comment:
You can of course, choose any size interval for forming the regression
table. For me, the 90 and 30 day tables work best. However, you should
verify any entry in the regression table, by looking at it's chart.
The www.BigCharts.com charts are excellent and they are free.

From Joe N. ( Question #1 )
How do you compute maximum gain per unit risk?
...................................................................................................Joe
The data is downloaded daily from fidelity. It is corrected
for all payouts etc. Linear regression is performed on each
fund. The standard deviation ( Risk ) is computed from the
data residuals about the regression fit. The "Gain" is defined
as the ordinate intercept of regression fit at the end of the
subject time window. Finally, all the regression data is sorted
and ranked, by the maximum gain per unit risk ratio.
![]()
From Joe N. ( Question #2 )
Have you done any historical back testing?
Joe
No I have not. But I have used this method daily since 82.
Also, because it is simply a regression formula, there is no real
question about what it does. The real question, is when does it
produce good results and when does it breakdown.
The method works best when a "uniform" up trend is in place.
At a market correction, you no longer have a single trend,
in fact you have two trends, one up, the other down.
The method will of course yield results, but the major premise
of a uniform trend has been violated, and the results may be
close to nonsense.
Good Luck With Your Investments!
