From the John Magee Market Letters, December 15, 1984 by Richard McDermott
The Elliott Wave Theory: perspective and comments
This week we had the pleasure of attending the December meeting of the Market Technicians Association of New York.
Long-term subscribers will remember the MTANY as the organization that honored John Magee with its “Man of the Year” award in 1978. The speaker was Robert Prechter, publisher of “The Elliott Wave Theorist,” an investment advisory which bases its forecasts on interpretations of R. N. Elliott’s work on the stock market.
Of primary interest to SAS subscribers are Prechter’s comments on technical analysis itself. The Elliott Wave Theory, it must be remembered, is really no more than a “catalog”
of stock market price movements, laid one on top of the other, so to speak, until a grand, underlying, and enduring pattern is observed; in short, pure technical analysis. Among Prechter’s defi nitions and observations regarding fundamental analysis are the following:
1. “First let’s defi ne ‘technical’ versus ‘fundamental’ data … technical data is that which is generated by the action of the market under study.”
2. “The main problem with fundamental analysis is that its indicators are removed from the market itself. The analyst assumes causality between external events and market movements, a concept which is almost certainly false. But, just as important, and less recognized, is that fundamental analysis almost always requires a forecast of the fundamental data itself before conclusions about the market are drawn. The analyst is then forced to take a second step in coming to a conclusion about how those fore- casted events will affect the markets! Technicians only have one step to take, which gives them an edge right off the bat. Their main advantage is that they don’t have to forecast their indicators.”
3. “What’s worse, even the fundamentalists’ second step is probably a process built on quicksand… . The most common application of fundamental analysis is estimating companies’ earnings for both the current year and next year, and recommending stocks on that basis… . And the record on that basis alone is very poor, as Barron’s pointed out in a June 4 article, which showed that earnings estimates averaged 18% error in the thirty DJIA stocks for any year already completed and 54% error for the year ahead.

Diagram B.1 Volatility formula. Illustrated is the formula for computing volatility. (1) Calculate the average return; (2) calculate the deviation of each return; (3) square each period’s deviation; (4) add them together; (5) divide the sum by the number of periods minus 1 to get the variance; and (6) take the square root.
The weakest link, however, is the assumption that correct earnings estimates are a basis for choosing stock market winners. According to a table in the same Barron’s article, a purchase of the ten DJIA stocks with the best earnings estimates would have produced a ten-year cumulative gain of 40.5%, while choosing the ten DJIA with the worst earnings estimates would have produced a whopping 142.5% gain.”
We enjoyed Prechter’s polished exposition of a technical approach different from our own. As for his observations about fundamental analysis, we simply could not agree more.

Diagrams B.2 and B.3 deal with portfolio risk and profit analysis. Illustrated are the sophisticated quantitative portfolio Profit and Risk reports of Delphic Options Research as implemented for Standard & Poor’s trading systems and Prudential Securities to give the reader an appreciation of the depth and complexity of professional thinking about risk and portfolio analysis. The originals of these reports were designed by Blair Hull and Lester Loops for their own use in market making.
Diagram B.2 Risk analysis.
Key: portfolio risk report. The Portfolio Risk Analysis screen summarizes delta, profi t, and sev- eral measures of risk for a portfolio of user-specifi ed stocks and options.
The screen displays:
STOCK SYM = The stock symbol;
STOCK POS = The stock position, or number of shares owned;
DELTAS TOTAL = The sum of the stock deltas and option deltas;
BETA = The stock beta for each stock (implementation pending);
$BETA = $The dollar risk due to movement of the general market: $Beta = (Delta × Stock Price) × Beta;
$DELT = An annualized risk fi gure based on Position imbalance: $Delta = (Total Delta × Stock Price) × Volatility;
$GAM = An annualized risk fi gure based on curvature of the position. A positive $Gamma indicates a backspread, and a negative $Gamma indicates a vertical position: $Gamma = Total Gamma × (Stock Price × Volatility);
$THETA = Theoretical dollar amount a position will gain or lose in one day if the stock price remains unchanged;
