The Ney Model
Buy what the big guys buy, and sell what the big guys sell!
-----------------------------------------------------------------------
------------------------------------------------
Richard Ney's model for stock market trading is quite simple: Buy what big money buys, and sell what big money sells. As he says in The Wall Street Gang, "I align myself with the specialist as he seeks to solve his inventory problems."
Simplicity personified! But it's a whole different ball game in practice, because you have to infer his price dynamics from properties of the market and use indicators of future market action based on the properties. This itself requires a model, an effective way of looking at prices and their changes.
----------------------------------------------
The ticker tape, as you may know, is a running account of stock market transactions, giving the stock ticker symbol, price, and number of shares of successive trades. Ney uses this data as a predictive tool -- an indicator not only for what a stock is likely to do in the immediate hours ahead, but also what it's likely to do for the intermediate and longer term, even a year or so.
To show how the tape might be used, he provides insight into three areas of importance:
------------------------------------------------------
The ticker tape is essential, says Ney. But:
... One can understand the tape and decipher its code of communication only when experience is shaped through memory -- or through the use of charts. ...In the final analysis, we need both in order to make financially rational decisions.
He says it's dangerous to believe you can take a stock's price trend and project it into the future, because the specialist uses existing investor techniques to mislead. This compels the specialist to change the trend in some way to gain the element of surprise needed to make his manipulations pay off. "As he moves from one phase or price level to another, however, his inventory objectives begin to reveal themselves in terms of specific trends."
For long-term trends, though, you pretty much have to rely on the charts, because the ticker tape won't help you.
-----------------------------------------------
The specialist's objectives can be classified in terms of three trends:
The overall trend picture is more complicated, however. For more details, see trends.

Ney identifies six categories of indicators one might apply in trading:
---------------------------------------------
According to Ney, an analyst using charts can obtain from the past behavior patterns of a specialist an indication of his behavior pattern in the future and predict what a stock will do.
[The] forces that determine specialist activity in the past are so demanding and definable to him that they are able to exercise a dominating influence over the major direction of his stock's price in the future. Within the limitations imposed by the secrecy in which government has shrouded specialist activity, I can only speculate that these forces are related to such different elements as the trading activity in the stock, its price structure, and [its] public supply and demand. Together, these are some of the factors that give each stock its distinctive pattern as the specialist contends with them in solving the inventory problems that lie on the path of his predetermined long term price objectives.
