Are stock purchases on NASDAQ trackable to personal information?
In the United States, when key people in a company buy or sell shares there are reporting requirements.  The definition of key people includes people like the CEO, and large shareholders. There are also rules that can lock out their ability to buy and sell shares during periods where their insider knowledge would give them an advantage. These reporting rules are to level the playing field regarding news that will impact the stock price.  These rules are different than the reporting rules that the IRS has to be able to tax capital gains. These are also separate than the registration rules for the shares so that you get all the benefits of owning the stock (dividends, voting at the annual meeting, voting on a merger or acquisition). The broker will probably submit records to the IRS, so there isn't anonymity at that level...
"The reason for this is arbitrage. In an free and open market, investments that are certain to generate above-average profits would do so by being sold cheaply, while having a high return on investment after that. But in a free market, prices are set by supply and demand. There is a high demand and little supply for investments that would certainly outperform the market. The demand is in fact so high, that the purchase price rises to the point of eliminating that excess return. And with high-frequency automated trading, that price hike is instant. But who would even want to sell such guaranteed outperformers in the first place? Of course, there are uncertainties associated with stocks, and individual stocks therefore move independently. As ""the market"" is an average, some stocks will therefore beat the market over certain time periods. That's random statistical variation. The only realistic path to above-average returns is to accept higher risks. As discussed above, nobody wants to sell you safe bets. But risky bets are another matter. Different actors will price risk differently. If you aren't worried much about risk, you can pick up stocks that are cheap by your standards. That is possible only because such stocks aren't cheap by risk-averse standards.  Looking a bit deeper, we see that arbitrage works in a free market because there's essentially perfect information. But risk is precisely the absence of such information, and that can lead to price variations. Yet, as the lack of information means a lack of certainty, you can't use this to reliably beat the market." The DOW is just an index, which is simply a group of stocks meeting the criteria for inclusion. In the case of the DOW, it's the 30 US stocks with the largest market capitalization, but other indices include many lesser stocks (such as the S&P500 or the Russell 2000). The fact that Holobeam is no longer a constituent of the DOW30 probably shouldn't be taken in and of itself as a signal to sell the stock. As far as I can tell, HOOB stock is still trading on the Nasdaq exchange. However, it is extremely ill-liquid, which means that there are very few people willing to buy or sell it. Whether or not this would work to your advantage is almost entirely down to luck - it depends whether there is a keen buyer out there at the time you try to sell. Yes, it's possible and even common but it depends on your bank or broker. One of the main differences is that you might assume FX risk if your account is in EUR and you trade stock denominated in USD. You might also encounter lower liquidity or price differences if you don't trade on the primary exchange where stocks are listed, i.e. NYSE, Nasdaq... "The Minnesota Mining and Manufacturing Company was established in 1902 as a private company.  It first raised public funds around 1903 but had a limited shareholder base.  By around 1929, it was reported as being tradeable as an OTC (over-the-counter) stock but it's likely that shares were traded well before this.  On 14 Jan 1946, the stock was listed on NYSE.  On 26 Sep 1962 it became a constituent of the the S&P 500 index.  On 9 Aug 1976 it became a constituent of the Dow Jones Industrial Average. In 2002, the company's name changed to 3M Co. It appears that the data on Crunchbase's ""IPO Date"" is wrong on this one. However, there are several companies that appear to do an ""IPO"" and have trading prices prior.  This is quite typical of early-stage biotech companies that trade OTC prior to a major exchange listing and ""IPO"". An example of an IPO happening after a company became publicly tradeable is NASDAQ:IMRN (Immuron). They had an ""IPO"" on Nasdaq on 9 Jun 2017, yet they had been trading as an OTC/Pink Sheet stock for months prior. They also have been listed in Australia since 30 Apr 1999. http://www.nasdaq.com/markets/ipos/activity.aspx?tab=pricings&month=2017-06 Another example is NASDAQ:GNTY (Guaranty Banchshares Inc) which had an ""IPO"" and NASDAQ listing in May 2017. This was a Nasdaq stock in 1998, went OTC/pink sheet stock in 2005. It has been paying regular dividends since that time. Clearly the word ""Initial"" is subjective!  http://www.nasdaq.com/markets/ipos/activity.aspx?tab=pricings&month=2017-05" You can buy the data and process it on your own.  http://www.nyxdata.com/Data-Products/Daily-TAQ No of course not, they are privately held, have no relationship with publicly held financial institutions, do not mine and sell your information to publicly held corporations, do not play revolving door of board members, the board members own no stocks, fired and retired board members will never get on another board, they never lobby congress on behalf of extracting more money from the public, and never engage in insider trading for sure.  Nothing at all to do with Wall Street. There's still a paper trail for every transaction. There's gotta be a debit and credit in there somewhere. Plus these companies are supposed to be audited by an *independent* auditor who, if they're worth their salt, should be able to track down every penny. "At the bottom of Yahoo!
