OMGWTFBBQ said:Running fractal analysis on all US stocks that trade more than 250K in avg volume for the past 80 days (about), and also limiting them so that they must have over 1600 trading days of data (over 6 years) - looking for non-random breaks in the entropy...
The following stocks have better than random chances of going up (this is relatively long term, there might be some that are even better in the short term - but anything short term is going to have a large enough margin of error to negate the change in probability anyway):
(these are in order of highest probability to go up over time consistently - if you want I can reorder them in order of which will have the largest swings in movement - I believe TRO would be at the top in that one)
ESS
PNP
MGA
MRGE
TRO
CTSH
INKP
CEDC
MVL
MAC
NANO
POG
UHCO
CLI
HME
AFCO
EPIQ
REG
ADVP
If you just want some stocks that are good, but with no analysis and are as likely to go up or down as anything else, then:
G, MO, ENT, PFE, RNR, DEO, C, MC, KO, CSCO
Those are some well known and relatively highly traded stocks in a few different sectors.
By putting money into them evenly (10% into each), and then keeping that 10% constant over time, you mathematically are going to do at least as well as an index fund and have a very high probability of beating it on average over time.
It becomes easier the more stocks you spread it over (but conversely becomes less effective as you trade more if your trading fees negate the amount you can move).
In order to benefit most from this, you would likely want to avoid capital gains taxes and reduce you trading fees and therefore just update the portfolio once a year (redistributing the money so that they are all at 10% of the total money).
If you are going to do that though, you would find it even easier to just put your money in a mutual fund (I like Fidelity's biotech) or an index fund.
If you just want hot tips that are risky as hell, then put all of your money into either HEC or EVOL.

However, you can only use so much capital at a time to day trade due to the bid and ask of a stock.

Technically speaking, if you are going to daytrade then you only want to trade (2P-1)*$ on any trade - where P is the probability of that stock's upward movement for one day in the future (technically with adjusted error) and the dollar sign represents all of the money you have available to trade.
If you trade less, then you are not maximizing your trade, and if you trade more, you are taking on more risk than you should for the trade.
And Boulder - I personally trade in and out and of things, so the Enron sort of thing (not that I would have even been in it), is slightly less of a deal with limits set.
As for long term analysis - you would want to run the same entropy check on it over time to see what is changing as well.
Every single stock on the market will delist if given enough time.
tia373 said:How are you calculating your probability?
...
Are you an active day trader- a swing trader---- what is your style?
OMGWTFBBQ said:
Swing trader I guess.
At this point I am interviewing with a hedge fund to try and get in there. Hence why I am using all of the techniques that they use.
As for the probability, it is the same time series analysis that one can apply to anything that is Brownian motion.
A rough description is to take the change in value over time and then you want the end average of that the root mean square of that.
From there, where P is the probability, it is P = ((avg/rms)+1)/2
There is slightly more to it and it has a low enough error margin after about 2500 data points - although that can be changed by spreading over a larger number of stocks - if you are in 10 stocks, then your margin of error can be higher - meaning you can use fewer days to look at to calculate it.
I also have a system of neural nets and various other algorithms going against the stuff and I like when they are all in agreement with the probability code and technical indicators - that always points to an up day (TRO today for instance).
But yeah - we all have our systems.

BY THE WAY, YOU CAN CALCULATE PROBABILITY BUT CANNOT CALCULATE UNCERTAINTY

Please let me know and I will contact him.

If you are doing long term investing, that is a good strategy.
There are some interesting reasons behind it beyond the way you phrase it, but the more I write, the less people read, so I will just leave it as an agreement.
OMGWTFBBQ said:
As for your call caps part that I missed at first since it looked like a sig... all I can say is that you are entitled to your opinion on the matter. I would recommend highly, if you are interested of course, that you read up on fractals and chaos (it was a big deal in the mid nineties) and its application to the stock market. With that, you will want to read up on the analytical techniques in regards to Brownian motion. Mandlebrot is a good starting point since a lot of his fractal work was toward non-linear systems - financial markets being one of them. The Hurst component (or exponent - same thing) might be of interest to you in reference to determining the randomness of a time series.

You are right to some extent if you mean that you can't calculate when the next terrorist attack will be (although you can point to regularities in the multi-sigma events and the increasing likelihood of one coming again with increasing time). You can easily calculate the risk/reward ratios though.
Being aware of the difference between risk and uncertainty is crucial when dealing with large amounts of money.
OMGWTFBBQ said:
It would be over a month before I can know what freedoms I have to do such things. If I get either of two jobs that I am trying to get right now, then I am not sure I can legally take on outside clients.
But much of the code that I have written would allow automated trading with obvious constraints on which brokers he is dealing with.
OMGWTFBBQ said:
CollegiateLifter - I didn't say anything about the impossibility of multi-sigma events - just the low probability.
There is a big difference.
Many of the issues with the probability theory is whether you are treating the standard deviation as one over a normal Guassian curve - which is an inappropriate thing for application against the stock market since it won't deviate into the negative (if you are looking at the change in value, then it is more acceptable, but if you are looking at prices, they can't go negative, they just delist).
When you don't apply it to the proper curve (I'm blanking on the proper curve term name at the moment - I want to say lepto something, but without looking it up I am sure I am wrong on that) - then you have a more accurate spread - but still can never be totally on with the predictions of the next sigma event.

In the case of LTCM there were 'events' that should have never occured in the thousands of years on earth, but did nevertheless....
Anyway, all of these theoretical applications do rely on the efficient market hypothesis, right?
Mandinka2 said:Not to upset you OMG but I read a recent report on problems with applying Brownian motion type models to share prices - actuaries are mostly developing Markov regime switching models right now. Do your models build in allowances for volatility changes over time ? - there is a lot of empirical evidence to suggest that we see different volatility regimes - this is consitent with the rotational investment strategy using different fund managers depending on whether we are in a bear (choose value fund managers) or bull (growth fund managers) market. I'll try and dig it up and post up some of the results but there does appear to exist a high degree of dependence.
I'm finally curious as to the base assumption to your models , are they momentum based (firms which performed well in the past are likely to do so again in the future?).
Better than I expressed it , you should get that job.OMGWTFBBQ said:
I'm not sure if that answered your question or not.
