Insider trading of a linked security like an ETF your company has a heavy weighting in
If you are in a position to have information that will impact the shares of a stock or index fund and you use that information for either personal gain or to mitigate the losses that you would have felt then it is insider trading.  Even if in the end your quiet period passes with little or no movement of the stocks in question.  It is the attempt to benefit from or the appearance of the attempt to benefit from inside information that creates the crime.  This is the reason for the quiet periods to attempt to shield the majority of the companies employees from the appearance of impropriety, as well as any actual improprieties. With an index you are running a double edged sword because anything that is likely to cause APPLE to drop 10% is likely to give a bump to Motorola, Google, and its competitors.  So you could end up in jail for Insider trading and lose your shirt on a poor decision to short a Tech  ETF on knowledge that will cause Apple to take a hit.  It is certainly going to be harder to find the trade but the SEC is good at looking around for activity that is inconsistent with normal trading patterns of individuals in a position to have knowledge with the type of market impact you are talking about.
The main difference between an ETF and a Mutual Fund is Management. An ETF will track a specific index with NO manager input. A Mutual Fund has a manager that is trying to choose securities for its fund based on the mandate of the fund. Liquidity ETFs trade like a stock, so you can buy at 10am and sell at 11 if you wish. Mutual Funds (most) are valued at the end of each business day, so no intraday trading.  Also ETFs are similar to stocks in that you need a buyer/seller for the ETF that you want/have. Whereas a mutual fund's units are sold back to itself. I do not know of many if any liquity issues with an ETF, but you could be stuck holding it if you can not find a buyer (usually the market maker). Mutual Funds can be closed to trading, however it is rare. Tax treatment Both come down to the underlying holdings in the fund or ETF. However, more often in Mutual Funds you could be stuck paying someone else's taxes, not true with an ETF.  For example, you buy an Equity Mutual Fund 5 years ago, you sell the fund yourself today for little to no gain. I buy the fund a month ago and the fund manager sells a bunch of the stocks they bought for it 10 years ago for a hefty gain. I have a tax liability, you do not even though it is possible that neither of us have any gains in our pocket. It can even go one step further and 6 months from now I could be down money on paper and still have a tax liability. Expenses A Mutual Fund has an MER or Management Expense Ratio, you pay it no matter what. If the fund has a positive return of 12.5% in any given year and it has an MER of 2.5%, then you are up 10%. However if the fund loses 7.5% with the same MER, you are down 10%. An ETF has a much smaller management fee (typically 0.10-0.95%) but you will have trading costs associated with any trades. Risks involved in these as well as any investment are many and likely too long to go into here. However in general, if you have a Canadian Stock ETF it will have similar risks to a Canadian Equity Mutual Fund. I hope this helps. "Matt Levine:  &gt;Also, though, I found it hard to imagine that those Equifax executives were consciously insider trading. It would just be too dumb. Equifax's press release reporting the breach says that it ""discovered the unauthorized access on July 29 of this year and acted immediately to stop the intrusion,"" though it didn't announce it until yesterday because it was still investigating. The three executives filed Form 4s reporting sales on Aug. 1 and 2, days after the discovery. You could just about imagine them learning of the security breach, panicking, and selling everything -- except that they didn't sell everything. One sold about 4 percent of his stock holdings, another about 9 percent, another about 13 percent. Why do such comically obvious insider trading if you're only selling a small percentage of your stock? And indeed the company explained that these executives ""had no knowledge that an intrusion had occurred at the time."" I guess the time between ""tech person discovers a security breach"" and ""top executives discover it's a huge embarrassing crisis"" is more than a couple of days.  https://www.bloomberg.com/view/articles/2017-09-08/data-breaches-and-last-looks" you dont need any permits or be inside the US to trade the exact same securities on US exchanges. you can literally move your bitcoin from a chinese exchange to us exchange in seconds.  i don't see how you can possibly run into legal issues if anyone from outside the country can trade bitcoins on an exchange inside the country without any permit. a lot of these exchanges dont ask for ID or social security number anyways. none of it is government regulated. also trading anything is never a passive income. theres no such thing as an easy or obvious investment. there are always risks- and the actual risk is often deceivingly low This site has the best information I could find, other than a Bloomberg terminal:    Quantumonline.com QUANTUMONLINE.COM SECURITY DESCRIPTION:  SCANA Corp., 2009 Series A, 7.70% Enhanced Junior Subordinated Notes, issued in $25 denominations, redeemable at the issuer's option on or after 1/30/2015 at $25 per share plus accrued and unpaid interest, and maturing 1/30/2065 which may be extended to 1/30/2080. Interest distributions of 7.70% ($1.925) per annum are paid quarterly on 1/30, 4/30, 7/30 & 10/30 to holders of record on the record date which is the business day prior to the payment date (NOTE: the ex-dividend date is at least 2 business days prior to the record date). Distributions paid by these debt securities are interest and as such are NOT eligible for the preferential 15% to 20% tax rate on dividends and are also NOT eligible for the dividend received deduction for corporate holders. Units are expected to trade flat, which means accrued interest will be reflected in the trading price and the purchasers will not pay and the sellers will not receive any accrued and unpaid interest. The Notes are unsecured and subordinated obligations of the company and will rank equally with all existing and future unsecured and subordinated indebtedness of the company.

"Here is one ""other consideration"": don't, don't, don't sell based on insider information. Insider trading can land you in jail. And it's not restricted to top executives. Even overhearing a discussion about the current status of the acquisition talks can mean that you have insider information that you legally cannot act on in many jurisdictions. If you are just a regular employee, the SEC will likely not subject your dealings to special scrutiny, especially since lots of your colleagues will likely trade your company's shares at this point in time. And if you definitely hold insider info (for example, if you are intimately involved with the acquisition talks), you will likely have had a very serious warning about insider trading and know what you can and what you cannot do. Nevertheless, it's better to be careful here." Energy Transfer Partners, LP (stock symbol ETP) is the parent company of Dakota Access LLC, the developer of the Dakota Access Pipeline.  Since ETP is a publicly traded company, it is certainly possible to purchase the stock. To answer your questions: Would it not be possible to buy their stocks, bring down the price of the stocks and keep it there until investors pull out because it is financially unwise to these investors? You cannot artificially bring the price of a stock down by buying the stock.  Purchasing large enough amounts would theoretically cause the price to go up, not down. You could theoretically cause the stock to go down by shorting the stock (borrowing shares and then selling them), but it would take a lot of shares to do this, and may not be successful.  If not successful, your losses are potentially unlimited. Would it alternatively be possible to buy enough stock to have a voice in the operations of the company? Yes, you could theoretically purchase enough of the stock to control the company.  The market capitalization of ETP is currently $17.9 Billion; if you owned half of the stock, you would have complete control of the company.  But buying that much stock would certainly influence the price of the stock, so it would cost you more than half of that amount to buy that much stock. You could get yourself a voice at the table for less without owning a full half of the stock, but you would not have full control, and would need support from others to get the outcome you want. Alternatively, someone determined to exert their influence could theoretically make an offer to purchase the Dakota Access subsidiary from ETP, which might be less costly than purchasing half of the entire corporation. Even if an extremely wealthy person were to try one of these options and destroy this company, it wouldn't necessarily stop another company from building something similar.  The investors you purchased the company from would have billions of dollars to do so with. I understand now. Thank you. How important is the existence of effective price discovery tools in a market?   And the example that you gave of a farmer is good, but when I as the owner of a company, get futures regarding, say, the stocks that I own of my company, won't that be insider trading if I do that after knowing that the value of my stocks will fall? If people assume price discovery in this case, won't they also have to assume that I am doing insider trading? Your assumption that funds sold in GBP trade in GBP is incorrect. In general funds purchase their constituent stocks in the fund currency which may be different to the subscription currency. Where the subscription currency is different from the fund currency subscriptions are converted into the fund currency before the extra money is used to increase holdings. An ETF, on the other hand, does not take subscriptions directly but by creation (and redemption) of shares. The principle is the same however; monies received from creation of ETF shares are converted into the fund currency and then used to buy stock. This ensures that only one currency transaction is done. In your specific example the fund currency will be USD so your purchase of the shares (assuming there are no sellers and creation occurs) will be converted from GBP to USD and held in that currency in the fund. The fund then trades entirely in USD to avoid currency risk. When you want to sell your exposure (supposing redemption occurs) enough holdings required to redeem your money are sold to get cash in USD and then converted to GBP before paying you. This means that trading activity where there is no need to convert to GBP (or any other currency) does not incur currency conversion costs. In practice funds will always have some cash (or cash equivalents) on hand to pay out redemptions and will have an idea of the number and size of redemptions each calendar period so will use futures and swaps to mitigate FX risk. Where the same firm has two funds traded in different currencies with the same objectives it is likely that one is a wrapper for the other such that one simply converts the currency and buys the other currency denominated ETF. As these are exchange traded funds with a price in GBP the amount you pay for the ETF or gain on selling it is the price given and you will not have to consider currency exchange as that should be done internally as explained above. However, there can be a (temporary) arbitrage opportunity if the price in GBP does not reflect the price in USD and the exchange rate put together.
