When a fund drops significantly, how can I research what went wrong? [duplicate]
"Usually there are annual or semi-annual reports for a mutual fund that may give an idea for when a fund will have ""distributions"" which can cause the NAV to fall as this is when the fund passes the taxable liabilities to shareholders in the form of a dividend. Alternatively, the prospectus of the fund may also have the data on the recent distribution history that is likely what you want. If you don't understand why a fund would have a distribution, I highly suggest researching the legal structure of an open-end mutual fund where there more than a few rules about how taxes are handled for this case."
"I am sorry to hear that.   Well, finance is a VERY large field encompassing decades upon decades of research, and thousands of pages of research. This question is usually a difficult one to answer simply because of the scope. My usual answer to people is to browse around this sub and the internet and learn from that, and then for specific questions to ask.   For your purposes, take a look at investopedia.com. While here it's an ""okay"" source, for a beginner I think it's a good place to start.  Is there any specific thing you have a question about now?  I know you mentioned the Big Short and some other things. Just keep in mind anything coming from Hollywood will be *extremely* biased." I don't know how other people regard ZH; but I read it along with many other financial blogs for my dose of news.            The magnitude of the loss shouldn't be surprising to people though. [As early as mid-May, JPMorgan Chase suspended a $15 billion stock repurchase plan that was only approved two months previously in March.](http://www.reuters.com/finance/stocks/JPM/key-developments/article/2544789). $15 billion is a big (much too big) reserve for a (claimed by the media at the time) supposedly $2 billion loss. It was only a matter of time before that loss was going to get much, much bigger. In your other question about these funds you quoted two very different yields for them. That pretty clearly says they are NOT tracking the same index. Along with the above reasons, the fact that DHA are under investigation by the Federal Police, should be a red flag to any potential investor. The Federal Police aren't called in over parking fines.  The rules that are in place for effective and appropriate management appear to have been compromised. I would like to see DHA's marketing people explain why the Department of Finance called in the Feds. To clarify further, with any investment, the potential investor must satisfy beyond any doubt whether there's a problem with an individual or with the way the organisation is managed as a whole. Look at the Big Four banks. To complete the research I suggest wait until DHA release an appropriate public statement (hopefully a sensible one that is honest- but don't hold your breath). I can see parallels with the recent scandal with HSU. When management is being led away in handcuffs it may be too late to change your mind. From mid 2007 to early 2009 the DJI went down about 50 %. This market setback won't happen on a single day or even a few weeks.  Emergency funds should be in cash only. Markets could be closed for an unknown period of time.  Markets where closed September 11 until September 17 in 2001. Lipper publishes data on the flow of funds in / out of stock and bond funds: http://www.lipperusfundflows.com Robert Shiller works on stock market confidence indices that are published by Yale: http://som.yale.edu/faculty-research/our-centers-initiatives/international-center-finance/data/stock-market-confidence Generally, the answer to the availability of holdings of a given mutual fund on a daily basis is no. Thus, an API is non-existent. The reasons for the lack of transparency on a daily basis is that it could/would impact the portfolio managers ability to trade. While this information would not necessarily permit individuals from front running the fund manager's trades, it does give insight in to the market outlook and strategy the fund is employing. The closest you'll be able to get to obtaining a list of holdings is by reading the most recent annual report and the quarterly filings each fund is required to file with the SEC. "No one is quite sure what happened (yet).  Speculation includes: The interesting thing is that Procter & Gamble stock got hammered, as did Accenture.  Both of which are fairly stable companies, that didn't make any major announcements, and aren't really connected to the current financial instability in Greece.  So, there is no reason for there stock prices to have gone crazy like that.  This points to some kind of screw up, and not a regular market force. Apparently, the trades involved in this event are going to be canceled. Edit #1: One thing that can contribute to an event like this is automatic selling triggered by stop loss orders.  Say someone at Citi makes a mistake and sells too much of a stock.  That drives the stock price below a certain threshold.  Computers that were pre-programmed to sell at that point start doing their job.  Now the price goes even lower.  More stop-loss orders get triggered.  Things start to snowball.  Since it's all done by computer these days something like this can happen in seconds.  All the humans are left scratching their heads. (No idea if that's what actually happened.) Edit #2: IEEE Spectrum has a pretty concise article on the topic.  It also includes some links to follow. Edit #3 (05/14/2010): Reuters is now reporting that a trader at Waddell & Reed triggered all of this, but not through any wrongdoing. Edit #4 (05/18/2010): Waddell & Reed claims they didn't do it.  The House Financial Services Subcommittee investigated, but they couldn't find a ""smoking gun"".  I think at this point, people have pretty much given up trying to figure out what happened. Edit #5 (07/14/2010): The SEC still has no idea.  I'm giving up. :-)" "I'll give the TLDR answer. 1) You can't forecast the price direction. If you get it right you got lucky. If you think you get it right consistently you are either a statistical anomaly or a victim of confirmation bias. Countless academic studies show that you can not do this. 2) You reduce volatility and, importantly, left-tail risk by going to an index tracking ETF or mutual fund. That is, Probability(Gigantic Loss) is MUCH lower in an index tracker. What's the trade off? The good thing is there is NO tradeoff. Your expected return does not go down in the same way the risk goes down! 3) Since point (1) is true, you are wasting time analysing companies. This has the opportunity cost of not earning $ from doing paid work, which can be thought of as a negative return. ""With all the successful investors (including myself on a not-infrequent basis) going for individual companies directly"" Actually, academic studies show that individual investors are the worst performers of all investors in the stock market." I believe you are missing knowledge of how to conduct a ratio analysis. Understanding liquidity ratios, specifically the quick or acid-test ratio will be of interest and help your understanding. http://www.investopedia.com/terms/a/acidtest.asp Help with conducting a ratio analysis. http://www.demonstratingvalue.org/resources/financial-ratio-analysis Finally, after working through the definitions, this website will be of use. https://www.stock-analysis-on.net/NYSE/Company/Exxon-Mobil-Corp/Ratios/Liquidity "As an exercise, I want to give this a shot.  I'm not involved in a firm that cares about liquidity so all this stuff is outside my purview.  As I understand it, it goes something like this: buy side fund puts an order to the market as a whole (all or most possibly exchanges).  HFTs see that order hit the first exchange but have connectivity to exchanges further down the pipe that is faster than the buy side fund.  They immediately send their own order in, which reaches exchanges and executes before the buy side fund's order can.  They immediately put up an ask, and buy side fund's order hits that ask and is filled (I guess I'm assuming the order was a market order from the beginning).  This is in effect the HFT front running the buy side fund.    Is this accurate?  Even if true, whether I have a genuine issue with this... I'm not sure.  Has anyone on the ""pro-HFT"" side written a solid rebuttal to Lewis and Katsuyama that has solid research behind it?" An index will drop a company for several reasons:  A fund decides how close they want to mirror the index. Some do so exactly, others only approximate the index. "Thanks for the response.   I am using WRDS database and we are currently filtering through various variables like operating income, free cash flow etc.  Main issue right now is that the database seems to only go up to 2015...is there a similar database that has 2016 info?  filtering out the ""recent equity issuance or M&amp;A activity exceeding 10% of total assets"" is another story, namely, how can I identify M&amp;A activity? I suppose we can filter it with algorithm stating if company's equity suddenly jumps 10% or more, it get's flagged" There are at least a couple of ways you could view this to my mind: Make an Excel spreadsheet and use the IRR function to compute the rate of return you are having based on money being added. Re-invested distributions in a mutual fund aren't really an additional investment as the Net Asset Value of the fund will drop by the amount of the distribution aside from market fluctuation. This is presuming you want a raw percentage that could be tricky to compare to other funds without doing more than a bit of work in a way. Look at what is the fund's returns compared to both the category and the index it is tracking. The tracking error is likely worth noting as some index funds could lag the index by a sizable margin and thus may not be that great. At the same time there may exist cases where an index fund isn't quite measuring up that well. The Small-Growth Indexing Anomaly would be the William Bernstein article from 2001 that has some facts and figures for this that may be useful. "The larger macro funds, the ones struggling in this environment, need there to be a""normal"" amount of volatility in the market to make money. They need price action to provide buy/sell points, and to help them spot trends. The one way market we have been in for a long time makes this difficult/impossible. And then when we get two days in a row like we just had, it can really fuck them up and will lead them to take positions of at the worst time. And the loses are larger because all the macro funds use leverage, so a dollar loss could really become $3-6.  The index funds are winning right now, no doubt. But they will have thier day off reckoning too, we just don't know how that plays out...yet.  everyone put active mutual funds in the trash two years ago, and they are having the best year they have had in ages. It's all very cyclical. (Sorry for one paragraph, I'm on mobile.)"
