Chuzz: QT, you suggested that: You have a problem with William O'Neil truthfulness. QT: Prompted by your comment: William O'Neil is fond of making outrageous claims etc., Chuzz: Not at all. I question his methodology and his conclusions. TQ: Understood. Chuzz: The problem is that the entire A/D calculation is a black box, and the output from that box can't be compared to any objectively determined end point. QT: Perhaps less of a black box than one would initially view it to be. I see no attempt at nor claim made for an objectively determined end point and I am guessing at what you mean by that term, so I don't know if I am talking to that. He does say what finite series of data he uses. "last 13 weeks to determine if the stock has been under net accumulation buying or distribution selling." The beginning point is 13 weeks ago and the ending point is the day prior to trading.When we look at this tomorrow we would take the oldest day and eliminate it and add on yesterday.So each new day is added to the data and the oldest day is eliminated from consideration. At any given time when we use the data it consist of the last 13 weeks. With regard to that ‘objectively determined' portion of your statement, I think the method is strictly mathematical and subjectively employed. I know of no statement attributed to IBD to the contrary. If this is the case, I see no objective way to measure its validity unless by employing his ratings we find them to be more useful than not and to the degree that it is, and continues to be, useful, we can subjectively deem it to be valid for our purposes. Chuzz: The critical question ought to be how does O'Neil know that he is measuring what he claims to be measuring? TQ: I am not sure he or we can say for sure that he absolutely knows that big block buying or selling is strictly institutional action. In addition, he only talks in terms of heavy buying or selling. He also uses terms like 'may indicate institutional buying or selling'. One would think that if he knew for sure he would say so. He is not saying that he does know for sure. What he seems very convinced of,is his method for determining net accumulation and distribution. If, what you are skeptical about is his method of determining net accumulation and distribution,I understand that very well. I want to see it, feel it and see for my self whether or not it has validity to me. He on the other hand says it has validity but doesn't provide us with the actual method he uses, perhaps he wants to sell his paper. Perhaps he didn't want to make it available to the Wall Street Journal or to an Internet provider of similar information. He may be simply protecting his interests. I understand that. Lets look at what we do know. Dell can show a buy for 10,000 shares at, let us say $75.00, then a number of smaller sells at, lets say, 6 sells of 1000 shares at $ 75.250, 75.250, 75.125, 75.125 , 75.0625 and 75.00. In this example, we see that 10,000 shares were bought and 6000 shares were sold. So while the stock price remains the same, the net accumulation of stock, 4000 shares are temporarily taken off the table. Now it is reasonable to conclude that large blocks of buys are more likely to be institutional buys as opposed to ordinary buys. If they are institutional buys, they more likely will remain off the table, for longer periods of time than ordinary buys. This then creates a smaller pool of available stock and most likely, if this accumulation continues,the stock price will tend to go up. His ratings are an attempt to give an edge to the investor who wants to slant the probability of the stock going up in her or his favor. I could give you the converse situation using different numbers to demonstrate the distribution/same price scenario, but the thought of Dell in further distribution, at a time that I believe should be accumulation,at a price less than 75.00 is not palatable! Chuzz: Where is the demonstration that stocks with an A rating are being bought by institutional investors? QT: I see no demonstration of the kind that you and I would be most comfortable with. However,logic tells us that by definition, stocks with an E rating (under the heaviest of distribution) have less of a probability of being bought at the same time by Fund Managers than those with an A rating(under the heaviest of accumulation). Chuzz: This is quite different from the bulk of TA because there the mathematics (such as they are) are available for investigation and criticism. But in the case of A/D ratings who knows? TQ: Understood. It is a game of probabilities vs possibilities and the tools we use and the skill we employ to determine those are very important, but sometimes they, and we are imperfect. Well, I got up an hour ago to a message from the Chuzz and now it is time to get the Asian Market Wrap and then 'sleep slow'. Look forward to Maria's chirping as we near to the market opening, the bell and the sound of music! Life is good. It is what ever it is, it is. Sincere Regards, QT
