Is there an online cost-basis calculator that automatically accounts for dividend re-investments and splits?
Google Finance portfolios take into account splits and cash deposits/withdrawals. Reinvestment creates a nightmare when it comes time to do taxes, sadly. Tons of annoying little transactions that happened automatically... Here's one article trying to answer your question: http://www.smartmoney.com/personal-finance/taxes/figuring-out-your-cost-basis-when-youve-lost-the-statements-9529/ You could also try this thing: http://www.gainskeeper.com/us/BasisProIndividual.aspx But I couldn't tell you if it would help. If it makes you feel better, brokerages are now required by the IRS to track your basis for you, so for new transactions and assets you shouldn't end up in this situation. Doesn't help with the old stuff ;-) Calculating and adjusting cost basis accurately is a daunting task, but there is a (paid) online tool, NetBasis, which will automatically calculate and adjust your cost basis.  It is used by brokerage firms and Fortune 500 companies and is available to the public.  Go to netbasis.com. All you need are the purchase and sale dates and shares of the stock or mutual fund and the system has the rest of the information, such as corporate actions (splits, spin-offs, etc), pricing, and dividends and it also will apply the appropriate IRS rules for inherited and gifted shares. The regulation also gives investors the option to choose calculation methods.  Not only does NetBasis automatically calculate the method you choose, it will also give the results for all options and allow you to choose the best result. NetBasis also provides you with detailed supporting documentation which shows all of the calculations and the adjustments in chronological order. NetBasis has data going back as far as 1925, so it will accurately calculate cost basis for your old American Telegraph and Telephone shares. NetBasis also handles complex investment scenarios such as wash sales, short sales, return of capital, etc. Moderator's note: Disclosure: The answerer's profile indicates they are affiliated with NetBasis.
Putting your money in the same account as a parent could cause many problems, with very few benefits. One of you would have to claim the dividends and capital gains that the fund might earn during the year. That person might have to pay taxes on those earnings. You would have to find some way of figuring out how to split the costs, and somebody would have to reimburse the other. If one person wanted to sell, figuring out which shares to sell would be much more complex. If these are retirement accounts, which have maximum limits based on income, and the use of other retirement accounts, there is no way to co-mingle the funds. Even if it was possible to combine the funds, the reality is that two people decades apart have different investment goals, and risk tolerances, so the types of investments that a great for one, are very poor for the other. The only benefit is that an existing account would already have more than the minimum investment, so some investments would be easier to make. Also some investments have lower fees if you meet specific investment thresholds. If the fund increases in value by 10% in a year, it doesn't make a difference if the value at the start of the year was 10K or 100K. The rate is the same. The benefits are minor and few; the drawbacks are many; and some situations make it impossible to co-mingle the funds. "There are a few reason why the stock price decreases after a dividend is paid:  What's the point of paying a dividend if the stock price automatically decreases? Don't the shareholders just break even? Companies have to do something with their profits. They beholden to their shareholders to make them money either by increasing the share value or paying dividends. So they have the choice between reinvesting their profits into the company to grow the business or just handing the profits directly to the owners of the business (the shareholders). Some companies are as big as they want to be and investing their profits into more capital offers them diminishing returns. These companies are more likely to pay dividends to their shareholders. I assume the price of the stock ""naturally"" increases over the year to reflect the amount of the dividend payment. This is kind of a vague question but then doesn't it make it difficult to evaluate the fluctuations in stock price (in the way that you would a company that doesn't pay a dividend)? It depends on the company. The price may recover the dividend drop... could take a few days to a week. And that dependings on the company's performance and the overall market performance.  With respect to options, I assume nothing special happens? So say I bought $9 call options yesterday that were in the money, all of a sudden they're just not? Is this typically priced into the option price? Is there anything else I need to know about buying options in companies that pay dividends? What if I had an in-the-money option, and all of a sudden out of nowhere a company decides to pay a dividend for the first time. Am I just screwed? One key is that dividends are announced in advance (typically at least, if not always; not sure if it's required by law but I wouldn't be surprised). This is one reason people will sometimes exercise a call option early, because they want to get the actual stock in order to earn the dividend. For ""out of the ordinary"" large cash dividends (over 10% is the guideline), stock splits, or other situations an option can be adjusted: http://www.888options.com/help/faq/splits.jsp#3 If you have an options account, they probably sent you a ""Characteristics and Risks of Standardized Options"" booklet. It has a section discussing this topic and the details of what kinds of situations trigger an adjustment. A regular pre-announced <10% dividend does not, while a special large dividend would, is what I roughly get from it. That ""Characteristics and Risks of Standardized Options"" is worth reading by the way; it's long and complicated, but well, options are complicated. Finally, do all companies reduce their stock price when they pay a dividend? Are they required to? I'm just shocked I've never heard of this before. The company doesn't directly control the stock price, but I do believe this is automatic. I think the market does this automatically because if they didn't, there would be enough people trying to do dividend capture arbitrage that it would ultimately drive down the price." "You can calculate the ""return on investment"" using libreoffice, for example. Look at the xirr function. You would have 2 columns, one a list of dates (ie the dates of the deposits or dividends or whatever that you want to track, the last entry would be today's date and the value of the investment today. The xirr function calculates the internal rate of return for you. If you add money to the account, and the current value includes the original investment and the added funds, it will be difficult to calculate the ROI. If you add money by purchasing additional shares (or redepositing dividends by buying additional shares), and you only want to track the ROI of the initial investment (ignoring future investments), you would have to calculate the current value of all of the added shares (that you don't want to include in the ROI) and subtract that value from the current total value of the account. But, if you include the dates and values of these additional share purchases in the spreadsheet, xirr will calculate the overall IRR for you." The catch is that you're doing a form of leveraged investing. In other words, you're gambling on the stock market using money that you've borrowed. While it's not as dangerous as say, getting money from a loan shark to play blackjack in Vegas, there is always the chance that markets can collapse and your investment's value will drop rapidly. The amount of risk really depends on what specific investments you choose and how diversified they are - if you buy only Canadian stocks then you're at risk of losing a lot if something happened to our economy. But if your Canadian equities only amount to 3.6% of your total (which is Canada's share of the world market), and you're holding stocks in many different countries then the diversification will reduce your overall risk.  The reason I mention that is because many people using the Smith Maneuver are only buying Canadian high-yield dividend stocks, so that they can use the dividends to accelerate the Smith Maneuver process (use the dividends to pay down the mortgage, then borrow more and invest it). They prefer Canadian equities because of preferential tax treatment of the dividend income (in non-registered accounts). But if something happened to those Canadian companies, they stand to lose much of the investment value and suddenly they have the extra debt (the amount borrowed from a HELOC, or from a re-advanceable mortgage) without enough value in the investments to offset it. This could mean that they will not be able to pay off the mortgage by the time they retire! "What you seem to want is a dividend reinvestment plan (DRIP).  That's typically offered by the broker, not by the ETF itself.  Essentially this is a discounted purchase of new shares when you're dividend comes out.  As noted in the answer by JoeTaxpayer, you'll still need to pay tax on the dividend, but that probably won't be a big problem unless you've got a lot of dividends.  You'll pay that out of some other funds when it's due.  All DRIPs (not just for ETFs) have potential to complicate computation of your tax basis for eventual sale, so be aware of that.  It doesn't have to be a show-stopper for you, but it's something to consider before you start.  It's probably less of a problem now than it used to be since brokers now have to report your basis on the 1099-B in the year of sale, reducing your administrative burden (if you trust them to get it right). Here's a list of brokerages that were offering this from a top-of-the-search-list article that I found online: Some brokerages, including TD Ameritrade, Vanguard, Scottrade, Schwab and, to a lesser extent, Etrade, offer ETF DRIPs—no-cost dividend reinvestment programs. This is very helpful for busy clients. Other brokerages, such as Fidelity, leave ETF dividend reinvestment to their clients. Source: http://www.etf.com/sections/blog/23595-your-etf-has-drip-drag.html?nopaging=1 Presumably the list is not constant.  I almost didn't included but I thought the wide availability (at least as of the time of the article's posting) was more interesting than any specific broker on it. You'll want to do some research before you choose a broker to do this.  Compare fees for sure, but also take into account other factors like how soon after the dividend they do the purchase (is it the ex-date, the pay date, or something else?).  A quick search online should net you several decent articles with more information.  I just searched on ""ETF DRIP"" to check it out." You can register with an online broker. You can usually join most online brokers for free and only have to fund your account if you decide to place a trade. You may also check out the website of the actual companies you are interested in. They will provide current and historic data of the company's financials. For BHP you can click on the link at the bottom of this webpage to get a PDF file of past dividends from 1984. Check out the NASDAQ and NYSE websites(the exchange in which the stock is listed) for detailed information. Most of the websites which collate dividend payments generally have cash payments history only e.g. Dividata. And because a company has given stock dividends in the past doesn't guarantee such in the future, I believe you already know that. Hey Sheehan, I believe Schwab provides this info.  None of the online free portfolio managers I know of gives you this info.  The now defunct MS Money used to have this. The best thing to do is to use a spreadsheet.  Or you could use the one I use.  http://www.moneycone.com/did-you-beat-the-market-mr-investor/ . (disclaimer: that's my blog)
