Understanding the Nasdaq insider trading information
"Usually insiders are in a better position than you to understand their business, but that doesn't mean they will know the future with perfect accuracy. Sometimes they are wrong, sometimes life events force them to liquidate an otherwise promising investment, sometimes their minds change. So while it is indeed valuable information, as everything in fundamental analysis it must be taken with a grain of salt. Automatic Sell I think these refer to how the sell occurred. Often the employees don't get actual shares but options or warrants that can be converted to shares. Or there may be special predetermined arrangements regarding when and how the shares may be traded. Since the decision to sell here has nothing to do with the prospects of the business, but has to do with the personal situation of the employee, it's not quite the same as outright selling due to market concerns. Some people, for instance, are not interested in holding stock. Part of their compensation is given in stock, so they immediately sell the stock to avoid the headache of watching an investment. This obviously doesn't indicate that they expect the company will go south. I think automatic sell refers to these sorts of situations, but your broker should provide a more detailed definition. Disposition (Non Open Market) These days people trade through a broker, but there's nothing stopping you from taking the physical shares and giving them to someone in exchange for say a stack of cash. With a broker, you only ""sell"" without considering who is buying. The broker then finds buyers for you according to their own system. If selling without a broker you can also be choosy with who is buying, and it's not like anybody can just call up the CEO and ask to buy some stock, so it's a non-open market. Ultimately though it's still the insider selling. Just on a different exchange. So I would treat this as any insider sell - if they are selling, they may be expecting the stock to become less valuable. indirect ownership I think this refers to owning an entity that in turn owns the asset. For instance CEO of XYZ owns stock in ACME, but ACME holds shares of XYZ. This is a somewhat complicated situation, it comes down to whether you think they sold ACME because of the exposure to XYZ or because of some other risk that applies only to ACME and not XYZ. Generally speaking, I don't think you would find a rule like ""if insider transactions of so and so kinds > X then buy"" that provides guaranteed success. If such a rule was possible it would have been exploited already by the professionals. The more sensible option is to consider all data available to you and try to make a holistic evaluation. All of these insider activities can be bullish or bearish depending on many other factors." Their argument is mostly nonsense. Take someone like Tim Cook, CEO of Apple. He has a not very large salary, and makes a lot more money through stock bonuses. You would never, ever expect him to buy Apple shares. And assuming that he doesn't want to end up one day as the richest man in the cemetery, you would expect him to sell significant numbers of shares, independent on whether he expects Apple to go up or down. Insiders are prevented from buying or selling shares except at certain periods right after information is disclosed publicly. But. People have bills to pay and kids to put through college and whatnot. So an insider can set up a plan where shares are sold on a specific schedule and they have no control over number of shares or timing. These plans (covered under rule 10b5-1) allow insiders to generate cash flow without immoderately benefiting from their inside information. Sales under these plans can mostly be ignored when trying to figure out the fortunes of a company from insider trades.
&gt; The Facebook IPO wasn't a debacle.   It really depends on how you see the markets.  If they're just a way for companies to rip off gullible investors, then sure, it wasn't a debacle.  But everyone except FB lost out of this one, and it wasn't just that the price went down - it was also that NASDAQ's systems failed badly, causing significant additional losses and impending lawsuits.  I don't think NASDAQ could be happy about these results.  I'm really doubtful that early investors are happy about losing a chunk of value overnight.  I doubt other companies who were trying to go public in this calendar year are overjoyed by this...  ...and frankly, I doubt that FB, overall, is happy about this result.  Lots of people there have stock options, options that they can't yet execute.  Lots more people there have options but decided to wait.  Some people who sold a lot of their stock are personally happy - but is this good for Facebook as a company?  I don't think so.  After having an almost exclusively winning profile, they become a public company, and stumble really badly right out of the gate... it'll take years to erase the bad perception created by this.  So unless you're one of a tiny number of FB insiders, this _was_ a debacle. "Fuck it, we'll do it live: &gt; Smart investors don't time markets. If they miss a wave, they search for the next one and get themselves in position. Why this is hard for most investors is because buying what is not popular is frightening to them. Timid investors are like sheep going along with the crowd. Or their greed gets them in when wise investors have already taken their profits and moved on. Wise investors buy an investment when it's not popular. They know their profits are made when they buy, not when they sell. They wait patiently. As I said, they do not time the market. Just like a surfer, they get in position for the next big swell. &gt; &gt; It's all ""insider trading."" There are forms of insider trading that are illegal, and there are forms of insider trading that are legal. But either way, it's insider trading. The only distinction is how far away from the inside are you? The reason you want to have rich friends who are close to the inside is because that is where the money is made. It's made on information. You want to hear about the next boom, get in and get out before the next bust. I'm not saying do it illegally, but the sooner you know, the better your chances are for profits with minimal risk. That is what friends are for. And that is financial intelligence.  Those are the paragraphs I'm talking about." "You have to read some appeals court cases see scholar.google.com , as well as SEC enforcement actions on sec.gov to get an understanding of how the SEC operates. http://www.sec.gov/spotlight/insidertrading/cases.shtml There are court created guidelines for how insider trading would be proven There is no clear line, but it is the ""emergency asset injunctions"" (freezing your assets if you nailed a suspiciously lucrative trade) you really want to avoid, and this is often times enforced/reported by the brokers themselves since the SEC does not have the resources to monitor every account's trading activities. There are some thin lines, such as having your lawyer file a lawsuit, and as soon as it is filed it is technically public so you short the recipient's stock. Or having someone in a court room updating you on case developments as soon as possible so you can make trades (although this may just be actually public, depending on the court). But the rules create the opportunities Also consider that the United States is the most strict country in this regard, there are tons of capital markets and the ideals or views of ""illegal insider trading"" compared to ""having reached a level of society where you are privileged to obtain this information"" vary across the board contains charts of countries where an existing insider trading prohibition is actually enforced: http://repository.law.umich.edu/cgi/viewcontent.cgi?article=1053&context=articles https://faculty.fuqua.duke.edu/~charvey/Teaching/BA453_2005/BD_The_world.pdf Finally, consider some markets that don't include equities, as trading on an information advantage is only applicable to things the SEC regulates, and there are plenty of things that agency doesn't regulate. So trying to reverse engineer the SEC may not be the most optimal use of energy" The amount of money spent on compliance to prevent insider trading alone probably dwarfs the cost it may impose on the markets.   But separately from that, the information that insider has is obviously going to get out, right? If it were spread through word of mouth heterogeneously and not released to all market participants at once, you eliminate or greatly diminish the value of ultra high frequency trading, which has become a useless arms race that probably doesn't add much value to society.  In the world of information, there's no clear marking that says *public* and *non-public*, but rather many shades between. I just don't think it's really worth pursuing except in the case of actual company insiders. We should be focusing our limited energy elsewhere, in my opinion. SEC Form 3 and SEC Form 4 are filed when insiders make share/derivatives acquisitions, transfers, sells and buys There is a time limit AFTER the action where they can be filed, such as 12 business days, so this can be a substantial amount of time after the effect on the market, depending on your strategy. You can aggregate these forms from SEC sources or from third party websites and services. In some cases, types of insider trading are permissible at certain intervals, so if you learn about when certain shares become unlocked, you can try to predict what insider actions will be and share price movements around those times. People are trying ideas like this, actually.  Though they generally aren't very public about it.  While keshlam ventures into hyperbole when mentioning Watson, he is certainly correct human language parsing is a extremely hard problem. While it is not always true that the big players will know before the news (sometimes that would qualify as insider trading).  The volume spike that you mention generally comes as the news arrives to the major (and minor) players.  So, if you have an algorithm run after the volume spike the price will likely have adjusted significantly already. You can try to avoid this by constantly scanning for news on a set of stocks however this becomes an even harder problem.  Or maybe by becoming more specific and parsing known important and specific news sources (farm report for instance) and trying to do so faster than anyone else.  These are some methods people use to not be too late. To be flippant: it is illegal because it is against the law; there is no considered involved, it just is. To elaborate, part of the illusion of the stock exchange and other market-like entities is that of (apparent) fairness. If I think a stock will go up because it is involved in a growing industry, that is generally public information.  Conversely if I have a dim view of a particular company because of its track record of product launches, that is similarly out in the open. A secret formula is something that I invented or discovered, not (presumably) something that I stole from someone else. To stretch that further: If I notice that Company X stock always moves with Company Y stock, that is indeed something that I have found, that I can try to profit from.  It is secret to me, but not particularly dependent upon information not available to others, just that my interpretation is better. So trading on information in the public domain is fine, as it preserves the principal of fairness I mentioned, whereas inside knowledge breaks that principal. If the share is listed on a stock exchange that creates liquidity and orderly sales with specialist market makers, such as the NYSE, there will always be a counterparty to trade with, though they will let the price rise or fall to meet other open interest.  On other exchanges, or in closely held or private equity scenarios, this is not necessarily the case (NASDAQ has market maker firms that maintain the bid-ask spread and can do the same thing with their own inventory as the specialists, but are not required to by the brokerage rules as the NYSE brokers are).  The NYSE has listing requirements of at least 1.1 million shares, so there will not be a case with only 100 shares on this exchange.
