Karen the Supertrader - TastyTrade Hybrid Experiment

So, the onus is on the guys doing the experiment to publish their trade logs, in real time, over a statistically significant increment of time.

They have been doing that on the Yahoo boards. Get yourself together... Or just keep following Bobby. :)

By the way what is your definition of statistically significant increment of time? 10000 years? You know what? I will wait for someone who has a statistically meaningful number of posts to discuss this.

Oh my. You're a charmer. A little prickly, too. You must not be terribly sure of yourself. Your tenor is pretty classic: stentorian True Believer. I question you, and you fall back onto an argument of ... seniority? Really? Because I guarantee you you'd lose that contest IRL. Not that this is a contest. It's a friendly debate. Right? You remember how to be friendly, don't you? And how to debate? Bueller? Bueller?

You shouldn't find that threatening. I'm just one guy (one guy who has generated a helluva lot of alpha in his time (He types, from his Hollywood Hills compound...)) so you can ignore me without rancor. Okay?


Except your profile says you're a girl. (Caitlyn?) And for someone who "has insight into Jim Simon's quant shop" and considers retail trading success as "noise," it's surprising you can't even spell Ray Dalio's last name correctly in a previous post:

Having said that, I agree with your point about Karen and how the big boys would follow her strategies if they were so profitable. But it's too bad ET has so many questionable posters and posers.

Is this the paper? It states that the 87 crash was a 20 sigma event.

Brexit is considered a 12 sigma event in GBUSD (I had a short naked position). SPX not so much.

I thought sigma was the relationship to defects in manufacturing.
As in 6 sigma.
What is 12 sigma and 20 sigma and how does it relate to options and stock trading?

Yes its similar. Sigma is short for standard deviation. Six Sigma relates to the percentage of defect-free products a manufacturing process creates. A six sigma process is one in which 99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects (3.4 defective features per million opportunities).

In finance, standard deviation is often used as a measure of the risk associated with price-fluctuations of a given asset (stocks, bonds, property, etc.), or the risk of a portfolio of assets (actively managed mutual funds, index mutual funds, or ETFs). Standard deviation provides a quantified estimate of the uncertainty of future returns. Calculating the average (or arithmetic mean) of the return of a security over a given period will generate the expected return of the asset. For each period, subtracting the expected return from the actual return results in the difference from the mean. Squaring the difference in each period and taking the average gives the overall variance of the return of the asset. The larger the variance, the greater risk the security carries. Finding the square root of this variance will give the standard deviation of the investment tool in question.

https://en.wikipedia.org/wiki/Standard_deviation

So a 20 sigma move is a move of 20 standard deviations or a move that mathematically would be incredibly unlikely (2.75 * 10^-89 as stated in the paper) if the market returns were normally distributed. Which turned up not to be the case as these moves happen a lot more often.

HTH
 
Slightly offtopic, but if anybody is interested how Tom and Tony looked 8 years ago and how ToS was ran by them (well, Tony was just a teacher) check out Wall Street Warriors season 3 on Youtube. The show is very boring (so skip most of it) but these guys make it a little interesting.

I liked the 140 monitors wall for educational purposes, which was an overkill, but looked cool. Teaching the new costumers hand signal was also funny, after all they want them to use a software, not thousand years old smoke signals.

Nevertheless, a bit entertaining and a look back to old days, where they came from.

Oh yeah, Tony also mentioned that he never had a losing month while being an option trader. That is interesting compared to the fact that TastyTrade is unable to put up a clearly profitable portfolio...

Wow thank you so much for this tip!!! The Wall Street Warriors "lost season" that has finally surfaced! I so much love to watch this: Slick guys in suits talking money, sunglasses, houses in the Hamptons. This is so ridicoulous. And now Tom and Tony inbetween! This is so much fun.
Lets see how it continues ...in autumn 2008 :D.

I think that paper references the 20 sigma, anyway when you start talking 3-5% moves in the indexes you are gonna get hurt. You could look at options on GBP/USD and compare before during and after. Hope you came out okay on your position.

This is precisely why Karen strategy will blowup eventually (and so do others such as LTCM). The black swam is actually just a "grey" swam in finance world and happen quite frequently..

Here's what I know: You have 2K+ posts and a single "like". It's not hard to see why. With brittle, cranky pedants such as yourself spreading harmony and understanding, it's not hard to see why I'll be spending less time here.

I hereby apologize for misspelling Ray Dalio's last name. Cognitively, I used the handle of "dahlia", and my mnemonic spilled over. You do know what a mnemonic is, don't you?

Poser? I run a family office with around $50M aum. Started much, much smaller. Silicon Valley programmer from the '90s, shifted to working on Wall Street building black boxes. Built a bunch of proprietary stuff with everything from C to Matlab to proprietary ANNs.

Once upon a time, wrote extensively for the national press, which is why profile obfuscation.

Of course, all invalidated because I misspelled Dalio.

I think I know who the poser is.
