Finding stocks following performance of certain investor, like BRK.B for Warren Buffet
Remember that unless you participate in the actual fund that these individuals offer to the public, you will not get the same returns they will. If you instead do something like, look at what Warren Buffet's fund bought/sold yesterday (or even 60 minutes ago), and buy/sell it yourself, you will face 2 obstacles to achieving their returns: 1) The timing difference will mean that the value of the stock purchased by Warren Buffet will be different for your purchase and for his purchase. Because these investors often buy large swathes of stock at once, this may create large variances for 2 reasons: (a) simply buying a large volume of a stock will naturally increase the price, as the lowest sell orders are taken up, and fewer willing sellers remain; and (b) many people (including institutional investors) may be watching what someone like Warren Buffet does, and will want to follow suit, chasing the same pricing problem. 2) You cannot buy multiple stocks as efficiently as a fund can. If Warren Buffet's fund holds, say, 50 stocks, and he trades 1 stock per day [I have absolutely no idea about what diversification exists within his fund], his per-share transaction costs will be quite low, due to share volume. Whereas for you to follow him, you would need 50 transactions upfront, + 1 per day. This may appear to be a small cost, but it could be substantial. Imagine if you wanted to invest 50k using this method - that's $1k for each of 50 companies. A $5 transaction fee would equal 1% of the value of each company invested [$5 to buy, and $5 to sell]. How does that 1% compare to the management fee charged by the actual fund available to you? In short, if you feel that a particular investor has a sound strategy, I suggest that you consider investing with them directly, instead of attempting to recreate their portfolio. Since nobody seems to have an answer here is the list I've came up so far: I'll keep adding to the list - also feel free to edit or comment if can add to the list. A couple points, first you don't point out what investors you want to invest with, and second BRK.B does not track anything; it is just a very small slice of his entire holdings BRK.A minus the voting rights. One solid way to go would be to buy BRK.B and also a tech ETF like QQQ, or XLK, ..or both. Since the vast majority of fund managers/big investors run private entities, it's not possible to track their performance. It's possible to look at what they are holding (that's never real-time information) and emulate their performance.
"Thanks for pointing out [the study](http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1748851). It's a slightly different cause than what I was describing when I posted this. Specifically, they show an effect not when the names get confused, but rather when the name similarity simply brings more attention to the stock. I was surprised nobody mentioned that in response to my post.  But also interesting is that they had to control for simple confusion between stock symbols, which implies that ticker confusion has a known effect. So I dug into research on that and quickly found [this study](http://www.efmaefm.org/0EFMAMEETINGS/EFMA%20ANNUAL%20MEETINGS/2010-Aarhus/EFMA2010_0161_fullpaper.pdf) found ""a high positive correlation between returns on two matching stocks with similar ticker symbols""." No. You're lucky, maybe, but not really a successful investor. Warren Buffet is, you're not him. Sometimes it is easier to pick stocks to bid on, sometimes its harder. I got my successes too. It is easier on a raising market, especially when it is recovering after a deep fall, like now. But generally it is very hard to beat the market. You need to remember that an individual investor, not backed by deep pockets, algo-trading and an army of analysts, is in a disadvantage on the market by definition. So what can you do? Get the deep pockets, algo-trading and an army of analysts. How? By pooling with others - investing through funds. Assuming you were immersed in math with your CS degree, the book **'A Non-Random Walk Down Wall Street' by Andrew Lo** is a very interesting book about the random walk hypothesis and it's application to financial markets and how efficient markets might not necessarily imply complete randomness.    Lots of higher level concepts in the book but it's an interesting topic if you are trying to branch out into the quant world.  The book isn't very specific towards algorithmic trading but it's good for concept and ideas.  Especially for general finance, that will give you a good run down about markets and the way we tackle modern finance.    **A Random Walk Down Wall Street** (which the book above is named after) by **Burton Malkiel** is also supposed to be a good read and many have suggested reading it before the one I listed above, but there really isn't a need to do so.    For investing specifically, many mention **'The Intelligent Investor' by Benjamin Graham** who is the role model for the infamous Warren Buffet.  It's an older book and really dry and I think kind of out dated but mostly still relevant.  It's more specifically about individual trading rather than markets as a whole or general markets.  It sounds like you want to learn more about markets and finance rather than simply trading or buying stocks.  So I'd stick to the Andrew Lo book first.    ---  Also, since you might not know, it would be a good idea to understand the capital asset pricing model, free cash flow models, and maybe some dividend discount models, the last of which isn't so much relevant but good foundations for your finance knowledge.  They are models using various financial concepts (TVM is almost used in every case) and utilizing them in various ways to model certain concepts.  You'd most likely be immersed in many of these topics by reading a math-oriented Finance book.  Try to stay away from those penny stock trading books, I don't think I need to tell a math major (who is probably much smarter than I am) that you don't need to be engaging in penny stocks, but do your DD and come to a conclusion yourself if you'd like.  I'm not sure what career path you're trying to go down (personal trading, quant firm analyst, regular analyst, etc etc) but it sounds like you have the credentials to be doing quant trading.    ---  Check out www.quantopian.com.  It's a website with a python engine that has all the necessary libraries installed into the website which means you don't have to go through the trouble yourself (and yes, it is fucking trouble--you need a very outdated OS to run one of the libraries).  It has a lot of resources to get into algorithmic trading and you can begin coding immediately.  You'd need to learn a little bit of python to get into this but most of it will be using matplotlib, pandas, or some other library and its own personal syntax. Learning about alpha factors and the Pipeline API is also moderately difficult to get down but entirely possible within a short amount of dedicated time.     Also, if you want to get into algorithmic trading, check out Sentdex on youtube.  He's a python programmer who does a lot of videos on this very topic and has his own tool on quantopian called 'Sentiment Analyzer' (or something like that) which basically quantifies sentiment around any given security using web scrapers to scrape various news and media outlets.  Crazy cool stuff being developed over there and if you're good, you can even be partnered with investors at quantopian and share in profits.    You can also deploy your algorithms through the website onto various trading platforms such as Robinhood and another broker and run your algorithms yourself.    Lots of cool stuff being developed in the finance sector right now.  Modern corporate finance and investment knowledge is built on quite old theorems and insights so expect a lot of things to change in today's world.  ---  With a math degree, finance should be like algebra I back in the day.  You just gotta get familiar with all of the different rules and ideas and concepts.  There isn't that much difficult math until you begin getting into higher level finance and theory, which mostly deals with statistics anyways like covariance and regression and other statistic-related concepts.  Any other math is simple arithmetic. "See Berkshire Hathaway Inc. (BRK-A) (The Class A shares)  and it will all be clear to you. IMHO, the quote for the B shares is mistaken, it used earning of A shares, but price of B. strange. Excellent question, welcome to SE.  Berkshire Hathaway is a stock that currently trades for nearly US$140,000. This makes it difficult for individual investors to buy or sell these shares. The CEO Warren Buffet chose to reinvest any profits which means no dividends, and never to split the shares, which meant no little liquidity.  There was great pressure on him to find a way to make investing in Berkshire Hathaway more accessible. In June '96, the B shares were issued which represented 1/30 of a share of the Class A stock. As even these ""Baby Berks"" rose in price to pass US$4500 per share, the stock split 50 to 1, and now trade in the US$90's.  So, the current ratio is 1500 to 1. The class B shares have 1/10,000 the voting rights of the A. An A share may be swapped for 1500 B shares on request, but not vice-versa." There can be the question of what objective do you have for buying the stock. If you want an income stream, then high yield stocks may be a way to get dividends without having additional transactions to sell shares while others may want capital appreciation and are willing to go without dividends to get this. You do realize that both Pfizer and GlaxoSmithKline are companies that the total stock value is over $100 billion yes? Thus, neither is what I'd see as a growth stock as these are giant companies that would require rather large sales to drive earnings growth though it may be interesting to see what kind of growth is expected for these companies. In looking at current dividends, one is paying 3% and the other 5% so I'm not sure either would be what I'd see as high yield. REITs would be more likely to have high dividends given their structure if you want something to research a bit more. True on the second point. It is information based. My bad.  With regard to the first point, I don't think he's Jesus returned. He makes plenty of mistakes but he does provide the return record of a very disparate group of investors following the same method. That method may not work anymore (hard to say) but I think it does. I'm obviously a true believer.   With respect to third point, I don't think you were being a dick. Enjoyed the debate. Thanks for the perspective Yes definitely  Warren Buffet averaged returns of only around 21% throughout his 40 years in business.  ROE of 23% is probably more than double the ROE of most companies , whats more as the saying goes its easier to grow sales from 1 million to 100 million than to grow sales from 100 million to 10 billion Yes, Alpha Vantage. As MasticatedTesticle points out, it is worth asking where it originally comes from, but it looked to me like a solid source for, in particular, intraday trading data. Additionally, Yahoo finance is done on R (zoo, PerformanceAnalytics libraries don't work anymore as far as I can tell). The numbers look right to me tho, let me know if things are off. I would say any of the top weighted stocks in the XLK etf. I wouldn't use a leader like IBM Goog or aapl. If anything, try and find one that is not extremely recognizable and present it like you discovered this particular stock in this sector you follow closely. Value investing is just an investment strategy, it's an alternative to technical investing. Buffet made money picking stocks.  It's not obvious how that adds value, but it does. Everything about the stock market is ultimately about IPOs. Without active trading, of stocks after issue, no one would buy at the IPO.  The purpose of an IPO is to finance the long-term growth of a business, which is the point in the process where the value to the people gets created.  There is a group of elites that needs to be dealt with, you're correct, but I worry that your definition of this group is overly broad. it's kind of like a circular loop:  i think he would suggest identifying strategies/portfolio managers who have demonstrated outperformance in a persistent manner.  Thing is, that's also really hard to do.  I think empirically, MPT suffers when the market does. By diversifying, you'll only be down less. He's suggesting shooting for absolute returns -- no matter what the market does, he wants to see positive gains.  (a lot) easier said than done "The first article you link clearly refers to Warren Buffet and doesn't, in regard to taxes, refer in any way to Berkshire Hathaway. The second article you link is titled, ""Ways Professional Traders Can Save Big At Tax Time."" Berkshire Hathaway is not a firm primarily engaged in trading. It is engaged in investing in companies that it feels offer long-term growth and appreciation. In some cases, their investment is in the entire company; in others, a very large percentage of its total capitalization. Trading, on the other hand, involves buying stocks, bonds, futures, etc. for near-term resale, ideally at a profit. Stock speculation is a risky and complex occupation because the direction of the markets are generally unpredictable and lack transparency.  As has been mentioned above, we are confident that Berkshire Hathaway use every technique at its disposal to reduce its tax burden. I am confident, as well, that they spend considerable effort and expense to be certain that they are never discovered making errors in their tax returns." No, there is no such list, as the other answers mention it is practically impossible to compile one.  However you can see the institutional investors of a public company.  MSN Money has this information available in a fair amount of details.  For example see the Institutional Investors of GOOG Very interesting. I would like to expand beyond just precious metals and stocks, but I am not ready just to jump in just yet (I am a relatively young investor, but have been playing around with stocks for 4 years on and off). The problem I often find is that the stock market is often too overvalued to play Ben Graham type strategy/ PE/B, so I would like to expand my knowledge of investing so I can invest in any market and still find value. After reading Jim Rogers, I was really interested in commodities as an alternative to stocks, but I like to play really conservative (generally). Thank you for your insight. If you don't mind, I would like to add you as a friend, since you seem quite above average in the strategy department. He owns some giants. I'd bet Coca-Cola is his biggest cash cow.   This is a non-story. The revenue naturally follows actual value provided, as opposed to buying and selling shares with the swings of the stock market.   Buffet buys and holds, and builds and collects the revenue from his companies, that's been his core philosophy since the beginning.
