Tracking down forgotten brokerage account
A company as large as Home Depot will have a fairly robust Human Resources department and would probably be able to steer you in the right direction: odds are they know the name of the brokerage and other particulars. I did some googling around, their # is  (1-866-698-4347). Different states have different rules about how long an institution can have assets abandoned before turning them over to the state. California, as an example, has an abandoned property search site that you can use.  That being said, I had some penny stocks sitting in a brokerage account I never touched for about 20 years and when I finally logged back in there they were, still sitting there.
As BrenBarn stated, tracking fractional transactions beyond 8 decimal places makes no sense in the context of standard stock and mutual fund transactions.  This is because even for the most expensive equities, those fractional shares would still not be worth whole cent amounts, even for account balances in the hundreds of thousands of dollars. One important thing to remember is that when dealing with equities the total cost, number of shares, and share price are all 3 components of the same value.  Thus if you take 2 of those values, you can always calculate the third: (price * shares = cost, cost / price = shares, etc).  What you're seeing in your account (9 decimal places) is probably the result of dividing uneven values (such as $9.37 invested in a commodity which trades for $235.11, results in 0.03985368550891072264046616477394 shares).  Most brokerages will round this value off somewhere, yours just happens to include more decimal places than your financial software allows. Since your brokerage is the one who has the definitive total for your account balance, the only real solution is to round up or down, whichever keeps your total balance in the software in line with the balance shown online. Brokerage firms must settle funds promptly, but there's no explicit definition for this in U.S. federal law. See for example, this article on settling trades in three days. Wikipedia also has a good write-up on T+3. It is common practice, however. It takes approximately three days for the funds to be available to me, in my Canadian brokerage account. That said, the software itself prevents me from using funds which are not available, and I'm rather surprised yours does not. You want to be careful not to be labelled a pattern day trader, if that is not your intention. Others can better fill you in on the consequences of this. I believe it will not apply to you unless you are using a margin account. All but certainly, the terms of service that you agreed to with this brokerage will specify the conditions under which they can lock you out of your account, and when they can charge interest. If they are selling your stock at times you have not authorised (via explicit instruction or via a stop-loss order), you should file a complaint with the S.E.C. and with sufficient documentation. You will need to ensure your cancel-stop-loss order actually went through, though, and the stock was sold anyway. It could simply be that it takes a full business day to cancel such an order. "It's easy for me to look at an IRA, no deposits or withdrawal in a year, and compare the return to some index. Once you start adding transactions, not so easy. Here's a method that answers your goal as closely as I can offer: SPY goes back to 1993. It's the most quoted EFT that replicates the S&P 500, and you specifically asked to compare how the investment would have gone if you were in such a fund. This is an important distinction, as I don't have to adjust for its .09% expense, as you would have been subject to it in this fund. Simply go to Yahoo, and start with the historical prices. Easy to do this on a spreadsheet. I'll assume you can find all your purchases inc dates & dollars invested. Look these up and treat those dollars as purchases of SPY. Once the list is done, go back and look up the dividends, issues quarterly, and on the dividend date, add the shares it would purchase based on that day's price. Of course, any withdrawals get accounted for the same way, take out the number of SPY shares it would have bought. Remember to include the commission on SPY, whatever your broker charges.  If I've missed something, I'm sure we'll see someone point that out, I'd be happy to edit that in, to make this wiki-worthy.  Edit - due to the nature of comments and the inability to edit, I'm adding this here. Perhaps I'm reading the question too pedantically, perhaps not. I'm reading it as ""if instead of doing whatever I did, I invested in an S&P index fund, how would I have performed?"" To measure one's return against a benchmark, the mechanics of the benchmarks calculation are not needed. In a comment I offer an example - if there were an ETF based on some type of black-box investing for which the investments were not disclosed at all, only day's end pricing, my answer above still applies exactly. The validity of such comparisons is a different question, but the fact that the formulation of the EFT doesn't come into play remains. In my comment below which I removed I hypothesized an ETF name, not intending it to come off as sarcastic. For the record, if one wishes to start JoesETF, I'm ok with it." You can use a tool like WikiInvest the advantage being it can pull data from most brokerages and you don't have to enter them manually. I do not know how well it handles dividends though. If you held the shares directly, the transfer agent, Computershare, should have had you registered and your address from some point on file.  I have some experience with Computershare, it turned out when Qwest restarted dividends and the checks mailed to the childhood home my parents no longer owned, they were able to reissue all to my new address with one telephone call.  I can't tell you what their international transfer policies or fees might be, but if they have your money, at least its found. Transfer Agent Computershare Investor Services serves as the stock transfer agent for Tellabs. If you need to transfer stock, change ownership, report lost or stolen certificates, or change your address, please contact Computershare Investor Services at +1.312.360.5389. It's true that most states have limits on what finders can charge if the listing is in state possession. If it is in the pre-escheat phase (that period of time before it goes to the state) then even if the money will eventually go to the state, the limits don't apply. Keane does a lot of work with transfer agents that handle the administrative work of stocks.  Other options that have a time limit include  I have a friend that was contacted by Keane. It turned out to be stock that her mother had when she worked for AMEX. She got busy with other things and got another letter from Keane. The stock increased in value and they wanted more money to help her even though they had already done the work of finding her. The money eventually went to the state and she was able to claim the full amount for FREE. If the suggestions I gave you don't get results, contact me through my web site and I'll try to help. Good luck! "Yes, there is a lot they are leaving out, and I would be extremely skeptical of them because of the ""reasons"" they give for being able to charge $0 commissions. Their reasons are that they don't have physical locations and high overhead costs, the reality is that they are burning venture capital on exchange fees until they actually start charging everyone they suckered into opening accounts. They also get paid by exchanges when users provide liquidity. These are called trade rebates in the maker-taker model. They will start offering margin accounts and charging interest. They are [likely] selling trade data to high frequency trading firms that then fill your stock trades at worse prices (Robinhood users are notorious for complaining about the fills). They may well be able to keep commissions low, as that has been a race to the bottom for a long time. But if they were doing their users any actual favors, then they would be also paying users the rebates that exchanges pay them for liquidity. Robinhood isn't doing anything unique as all brokers do what I mentioned along with charging commissions, and it is actually amazing their sales pitch ""$0 commissions because we are just a mobile app lol"" was enough for their customers. They are just being disingenuous." 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 ;-) The old school way would have been to identify some wealthy zip codes and cold call like a mofo.  At present I would prefer to find some retiring advisor and buy his book (that may mean leaving your current firm). The official source for the Dow Jones P/E is Dow Jones.  Unfortunately, the P/E is behind a pay-wall and not included in the free registration. The easiest (but only approximate) solution is to track against an equivalent ETF.  Here's  a list of popular indexes with an equivalent ETF. Source "Usually the new broker will take care of this for you. It can take a couple of weeks. If you are planning to go with Vanguard, you probably want to actually get an account at Vanguard, as Vanguard funds usually aren't ""No Transaction Fee"" funds with many brokers. If you are planning to invest in ETFs, you'll get more flexibility with a broker." Street name is not what you think it is in the question.  The broker is the owner in street name.  There is no external secondary owner information.   I don't know if there is available independent verification, but if the broker is in the US and they go out of business suddenly, you can make a claim to the SIPC. I work for a hedge fund, not wealth management, but I assume that client information is treated similarly. Misplacing it is a huge deal. The company will probably need to formally investigate it and inform all the clients involved. Even if they can prove that no one looked at the information it's going to make clients question the company's procedures. I could see it being a firing offense,depending on how many clients were affected and the nature of the data. Sorry if that's not what you wanted to hear. Its not public information but it would be hard to keep it a secret. By its very nature, a custodial bank has to interact with various brokers, middle office systems, back office systems - many of which are third party. And the investment firm will likely be giving out their custodial information to these third parties to set up interfaces and whatnot. The Roth-IRA or for that matter a regular IRA is generally not connected to your place of employment.  Now a 401(k) is linked to your place of employment. If the business no longer exists, they should have turned over the 401K. The US department of Labor has information regarding plans that have been abandoned. I suspect my plan is abandoned, but I have never received a notice of   plan termination. How could I find out if a QTA has elected to   terminate and wind up my 401(k) pension plan? EBSA has developed an Abandoned Plan searchable database to help   participants and beneficiaries find out if a particular plan is in the   process of being, or has been, terminated. The site is searchable by   plan name or employer name and will provide the name and contact   information for the QTA, if one exists.  If you do not have access to   a computer to conduct the search, you may contact one of EBSA’s   Benefits Advisors to assist you by calling toll-free, 1.866.444.EBSA   (3272).
