So of course the next big business idea is large unrollable printed vinyl top-views of cars. Get your employees to move them around a bit every morning, company's stocks start to rise.

Anyone who ever considers this sort of thing to be "unfair" or "cheating" should also consider how comparatively easy it is to make a nonsense of.

Who wants to go halfs with me on a large-format printer?

The line is not blurring. Non-public information is information owned by the company. This is different from information that is hard to acquire and hence, not available to everyone. You are making the same mistake the article does when you state this line is blurring.

I didn’t realize it was so cut and dry. How silly of me! I guess all of the work I’ve done providing legal advice to hedge funds on what is and isn’t insider trading since Preet Bahara first came to town was for nothing. Thanks for cle…

Do you have some qualified experience or situations you can point to? It sounds like you do, or should, given the qualifications you allude to. That would be a useful addition to this discussion.

They absolutely shouldn't play unless they like losing money. It is extremely hard for professional investors to beat the market who spend all day every day working on it. It is basically impossible for a collection of retail investors to beat the market. At best, retail investors are simply gambling.

> "At best, retail investors are simply gambling." that's just not true and is a gross over simplification. for one, not beating the market is NOOOOOT the same as losing money. For another, even if they do not beat the market, there are a lot of other benefits. People gain an understanding of how things like bonds and equities work. I cant tell you how many people (masters degree included) think you can loose more mo…

If you can beat the market over a 10-15 year period, you are in a very small group of extremely fortunate individuals (some of which are simply lucky). If you have beaten the market over the last 1-5 years, you likely invested in particular factors without really knowing it. Once those factors lose favor, you will significantly under perform the market.

I personally invest primarily in well diversified, extremely low cost ETFs and I buy 1 - 2 positions a year outside of that portfolio (right now the main one is bitcoin for me). But, I'm always looking around for something that I think can be a 10X return.

But... I rely on my primary diversified portfolio for my retirement and the single 1 or 2 investments I make outside of that are for fun, knowledge and I fully acknowledge gambling.

Why is trying the interests of retirees to shareholders "kind of dumb and fucked up"? I'm not even sure there is a valid distinction between the two groups. The retirees are shareholders.

Gee, I dunno, maybe think about it for a second. What does a 65 year-old lower middle-class retiree with some money stashed in a 401(k) have in common with an ExxonMobil shareholder aside from the need to generate as much profit as possible? Do you really think this makes sense from a public policy perspective, to pit the retirement needs of the old against, e.g., the environmental health of the young? Please spare m…

But couldn’t you argue in exactly the same way for disenfranchisement? Do you think retired people should be allowed to vote?

Nothing wrong with being investment savvy and all that jazz but obsessing over it doesn't sound healthy.

People can enjoy a fancy plate or 2.

They've been using satellites for over a decade now. The fact that you're hearing about it means there's not much value in this type of data anymore.... I reserve some room for being wrong here.

This type of data is ultimately used to predict revenue for consumer companies. Cellphone data and wifi data is much better for that type of prédiction.

There's a whole marketplace where companies with so-called "Alternative-data" sell their datasets to quant traders. Satellite imagery of farms, passenger traffic through airports, all sorts of random, seemingly disparate data.

The reason your free weather app asks for your location data isn't for "local weather forecasts". Well, it is, but that's a cost for them. The income comes from keeping that location tracking on all the time and selling which stores and dentists you go to. Someone can link the NYT story from a few months ago when this came to mainstream attention. Hedge funds also fly cesnas over refinery fields to look at the levels…

If anyone is profiting off my location I better get a cut of it haha. It's amazing what they can do and I enjoy data-centric trading strategies but we don't have to violate individual privacy.

This article is very wrong to confuse "material non-public information" with hard to acquire information like counting cars in satellite photos. Remember the Matt Levine test: insider trading is about theft, not fairness. When a company insider uses private company information to trade (or colludes with an outside party to do so) they are stealing material non-public information from the company for their own benefit…

Which part of the article do you think confuses MNPI with alternative data? It seemed that the purpose of the paper is to point out how the line between “public” information and “non-public” information is blurring for those who can afford access. And given how difficult it is to define insider trading that seems like a pretty accurate assessment to me. Alternative data firms are the new expert network firms in the w…

> And given how difficult it is to define insider trading that seems like a pretty accurate assessment to me. Alternative data firms are the new expert network firms in the wake of Rajaratnam.

I fail to see the parallel with Rajaratnam, since Rajaratnam was accused and convicted of insider trading on the basis of leaking from corporate insider executives(!) That's precisely the distinction that is being drawn in the comments here, between theft of insider information and the acquisition of difficult-to-intuit public information.

To answer your question, these parts:

> But technology is increasingly blurring the boundaries between public and private information, creating data opportunities that are legal, but are expensive and often require special expertise to access. “Technology was supposed to level the playing field, but what I see is the fence separating sophisticated and unsophisticated investors growing higher,” says Patatoukas, who is passionate about teaching his students to analyze public sources of financial information and finds the trend troubling. “That’s the dark side of big data. Our evidence suggests that unequal access to alternative data leaves individual investors outside the information loop.”

> In the aftermath of the financial crisis, there has been increased regulatory interest in the role of informed trading and disclosure requirements to protect the fairness and integrity of capital markets. With this in mind, Patatoukas hopes that the paper will get the attention of the regulators. “In a market setting where the line separating public from material non-public information is getting blurrier, the question that regulators need to answer is: What is their role in terms of leveling the playing field for individual investors?”

This is exactly right. If you're upset about this then you should be upset that hedge funds can afford to hire smarter analysts than you, which is just silly.

I agree, but where's this end up? Why would retail investors play a game where they're almost certain to lose?

b/c a well diversified portfolio of stocks will, in the aggregate, easily beat HF returns after 2/20 fees and even after 1/10 fees.

If this discussion is still narrowly tailored to the securities market, since this discussion was also about "insider trading", which is a unique prohibition to the securities market and not any other capital market then: Retail has no business in the securities market. thats where it ends up. stop playing. retail investors flocking to the stock market is a 40 year old meme that is built upon non-objective thought an…

Laziness? It's built on desperation. There were some solid ways to develop retirement strategies with lifelong careers, pensions, and other older retirement vehicles. However, pensions are largely irrelevant outside the public sector now, the older retirement vehicles have stagnated/become poor investments (like annuities, which have become a landmine for terrible fees), and what was left was 401ks and individual ret…

Yes, 401ks were hoisted on the public and threw the most responsible one's money into the stock market. Creating reliable liquidity for other institutional firms.

It is pretty amazing and ingenious.

No, it doesn't undermine the observation that retail shouldn't be playing.
