EMH is regarded as major principle And it is forwarding as a consequence of sysyemic iterative refinement.
As a consequence different players have to hold their own in the face of new influences that exploint opporutnities.
It is really exciting and fun to be a participant.
As a side note on some recent comments, consider this. What if a person can't correctly type an address.? What would happen if he confused the side of town the address is on? In my case that happened.
Also what does it mean if a thrid party isssues citations for illegal trading and then has to retract them? It probably means some accounts were involded and some money was made. If the SEC is looking at multiple accounts in a major brokerage does it mean they are looking at places that may bear fruit? They see what they are detecting over and over. If they are looking for whales doing insider trading and they keep getting hits, what do they do?
Lets call what the SEC did as Behavioral finance. They see under a type of "setup" a set of accounts operated under POA's. In EMH and BF terms this is a market anomally being caused by a person who "may be" influencing the market.
Is this perosn trading? Is this peson making money? They are looking at account records and they see a BF type B situation,namely: pre event abnormal returns and they do NOT see post event continuation on the part of this trader.
It is suggested to me to use a dignified approach to handle ET members who are less than organized or oriented.
Here is the situation. Because I fit the SEC profile for making money in a way that is abnormal and having high returns and the approach is flawless in BF terms, I must be a villan that takes advantage of normal market participants.
BF suggests that if a problem is occurrring, then reasonable changes in technique must be made.
That happened and the technique of the SEC changed to include thye possibility that some trading techniques could front run the market and, at the same time, not be criminal.
Anyone who wishes can check the SEC records and find out why they changed their technique to sharpen it up to not make mistakes.
Likewise anyone can change the side of town to the correct address and find, environmentally that part of town is 10 degrees cooler because of the neighborhood initiatives to eliminate heat islands community wide.
When people make mistakes, they get the consequences. Posters who make mistakes and reason poorly get to not have the opportunity to test the SEC's computers for insider trading profiles.
I have proven repeatedly to the SEC that I do not harm others by trading with a profile that simulates what they think is "insider trading". There are cool advantages of being a frontrunner who takes the market's off in terms of BF's "abnormal returns".
I'm going to use this "opportunity" as a segway to look at another third party effort to deal with reconciling X and Y where X is TA and Y is quantitative finance.
This group, the third party, will also attempt to create a lingua franca so a productive dialogue can begin.
EMH presently is being affected by a thing like HFT. For a trader using BF principles, we know this leads to examining the times when emotional flags suggest that there is a market anomaly at that time which is not handled optimally by the trader's approach. BF suggests making reasonable changes in technique to eliminate the anomally.
The segway begins with the third party saying: "In this paper we hope to bridge thgis gulf between tachnical analysis and quantitative finance by developing a systematic and scientific approach of technical analysis and by employing the now standard methods of empirical analysis to guage the efficacy of technical indicators over time and across securities." The third party is paid by several and, among others, NSF and the work is taking place @ MIT. See page 1708 of August 2000 Journal of Finance.
further, this group announces the general goal of TA: "The general goal of technical analysis is to identify regularities in the time seris of price by extracting non linear patterns from noisey data."
they found out somewhere that the human eye can perform this "signal extraction" quickly and accurately. In 2000 it was not common , they said, for a computer algorithm to do this.
So first, lets look at the human eye part with boxes.
