Mutual Funds Definition and Role
"I think you are asking about actively managed funds vs. indexes and possibly also vs. diversified funds like target date funds. This is also related to the question of mutual fund vs. ETF. First, a fund can be either actively managed or it can attempt to track an index. An actively managed fund has a fund manager who tries to find the best stocks to invest in within some constraints, like ""this fund invests in large cap US companies"". An index fund tries to match as closely as possible the performance of an index like the S&P 500. A fund may also try to offer a portfolio that is suitable for someone to put their entire account into. For example, a target date fund is a fund that may invest in a mix of stocks, bonds and foreign stock in a proportion that would be appropriate to someone expecting to retire in a certain year. These are not what people tend to think of as the canonical examples of mutual funds, even though they share the same legal structure and investment mechanisms. Secondly, a fund can either be a traditional mutual fund or it can be an exchange traded fund (ETF). To invest in a traditional mutual fund, you send money to the fund, and they give you a number of shares equal to what that money would have bought of the net asset value (NAV) of the fund at the end of trading on the day they receive your deposit, possibly minus a sales charge. To invest in an ETF, you buy shares of the ETF on the stock market like any other stock. Under the covers, an ETF does have something similar to the mechanism of depositing money to get shares, but only big traders can use that, and it's not used for investing, but only for people who are making a market in the stock (if lots of people are buying VTI, Big Dealer Co will get 100,000 shares from Vanguard so that they can sell them on the market the next day). Historically and traditionally, ETFs are associated with an indexing strategy, while if not specifically mentioned, people assume that traditional mutual funds are actively managed. Many ETFs, notably all the Vanguard ETFs, are actually just a different way to hold the same underlying fund. The best way to understand this is to read the prospectus for a mutual fund and an ETF. It's all there in reasonably plain English." Mutual funds buy (and sell) shares in companies in accordance with  the policies set forth in their prospectus, not according to the  individual needs of an investor, that is, when you invest money in (or withdraw money from) a mutual fund,  the manager buys or sells whatever shares that, in the manager's judgement,  will be the most appropriate ones (consistent with the investment policies). Thus, a large-cap mutual fund manager will not buy the latest hot small-cap stock that will likely be hugely profitable; he/she must choose only between various large capitalization companies. Some exchange-traded funds are fixed baskets of stocks. Suppose you will not invest in a company X as a matter of principle. Unless a mutual fund prospectus says that it will not invest in X, you may well end up having an investment in X at some time because the fund manager bought shares in X. With such an ETF,  you know what is in the basket, and if the basket does not include stock in X  now, it will not own stock in X at a later date. Some exchange-traded funds are constructed based on some index and track the index as a matter of policy. Thus, you will not be investing in X unless X becomes part of the index because Standard or Poor or Russell or somebody changed their minds, and the ETF buys X in order to track the index. Finally, some ETFs are exactly like general mutual funds except that you can buy or sell ETF shares at any time at the price at the instant that your order is executed whereas with mutual funds, the price of the mutual fund shares that you have bought or sold is the NAV of the mutual fund shares for that day, which is established based on the closing prices at the end of the trading day of the stocks, bonds etc that the fund owns.  So, you might end up owning stock in X at any time based on what the fund manager thinks about X.
I am a junior analyst at a fund of funds. I spend most of my time working on streamlining our process by helping one of the senior analysts create new models to replace our spreadsheets. I work during the summer since I am a student. The rest of my time in the office I simply research managers that we are looking into for the PM's and senior analysts. You definitely want good excel skills as an analyst. Coding is also a good skill to have depending on what sort of role you play. "For a non-ETF mutual fund, you can only buy shares of the mutual fund from the mutual fund itself (at a price that the mutual fund will reveal only at the end of the day) and can only shares back to the mutual fund (again at a price that the mutual fund will reveal only at the end of the day). There is no open market in the sense that you cannot put in a bid to buy, say, 100 shares of VFINX at $217 per share through a brokerage, and if there is a seller willing to sell 100 shares of VFINX to you at $217, then the sale is consummated and you are now the proud owner of 100 shares of VFINX. The only buyer or seller of VFINX is the mutual find itself, and you tell it that you ""want to buy 100 shares of VFINX and please take the money out of my checking account"". If this order is entered before the markets close at 4 pm, the mutual fund determines its share price as of the end of the day, opens a new account for you and puts 100 shares of VFINX in it (or adds 100 shares of VFINX to your already existing pile of shares) and takes the purchase price out of your checking account via an ACH transfer. Similarly for redeeming/selling shares of VFINX that you own (and these are held in an account at the mutual fund itself, not by your brokerage): you tell the mutual fund to that you ""wish to redeem 100 shares and please send the proceeds to my bank account"" and the mutual fund does this at the end of the day, and the money appears in your bank account via ACH transfer two or three days later.  Generally, these transactions do not need to be for round lots of multiples of 100 shares for efficiency; most mutual fund will gladly sell you fractional shares down to a thousandth of a share. In contrast, shares of an exchange-traded fund (ETF) are just like stock shares in that they can be bought and sold on the open market and your broker will charge you fees for buying and selling them. Selling fractional shares on the open market is generally not possible, and trading in round lots is less expensive. Also, trades occur at all times of the stock exchange day, not just at the end of the day as with non-ETF funds, and the price can fluctuate during the day too. Many non-ETF mutual funds have an ETF equivalent: VOO is the symbol for Vanguard's S&P 500 Index ETF while VFINX is the non-ETF version of the same index fund.  Read more about the differences between ETFs and mutual funds, for example, here." When interest rates rise, the price of bonds fall because bonds have a fixed coupon rate, and since the interest rate has risen, the bond's rate is now lower than what you can get on the market, so it's price falls because it's now less valuable. Bonds diversify your portfolio as they are considered safer than stocks and less volatile. However, they also provide less potential for gains. Although diversification is a good idea, for the individual investor it is far too complicated and incurs too much transaction costs, not to mention that rebalancing would have to be done on a regular basis. In your case where you have mutual funds already, it is probably a good idea to keep investing in mutual funds with a theme which you understand the industry's role in the economy today rather than investing in some special bonds which you cannot relate to. The benefit of having a mutual fund is to have a professional manage your money, and that includes diversification as well so that you don't have to do that. Hey man. First of all, having a firm understanding in SE is a blessing! Finance firms are actively looking to hire with software engineering skills from tech. The closer to your background skills, the easier it will be to get a job. If you don't want to be a programming drone for Goldman, i'd say algo trading or being a quant at a hedge fund would be an awesome gjg. If you definitely want to do investment banking (m&amp;a/ibd), focus on spinning your story and background targeting tech companies.   Just make sure you know why you want to go into finance and that role vs SE. Make sure you truly try to understand what investment banking/algo trading is and can explain it to your grandma. Above all, network, network, network. Good luck. To supplement Ben's answer: Following 'smart money' utilizes information available in a transparent marketplace to track the holdings of professionals.  One way may be to learn as much as possible about fund directors and monitor the firms holdings closely via prospectus. I believe certain exchanges provide transaction data by brokers, so it may be possible for a well-informed individual to monitor changes in a firms' holdings in between prospectus updates.  An example of a play on 'smart money':  S&P500 companies are reviewed for weighting and the list changes when companies are dropped or added. As you know there are ETFs and funds that reflect the holdings of the SP500.  Changes to the list trigger  'binary events' where funds open or close a position. Some people try to anticipate the movements of the SP500 before 'smart money' adjusts their positions. I have heard some people define smart money as people who get paid whether their decisions are right or wrong, which in my opinion, best captures the term. This Udemy course may be of interest: https://www.udemy.com/tools-for-trading-investing/ When you invest in an ETF or mutual fund, you're not investing in stocks or bonds. You're buying shares of a company that invests in stocks or bonds. This level of indirection is what makes it so bond funds do not 'mature.' Bonds inside of ETFs or mutual funds do have a maturity date. When they mature, the fund manager uses the principal value that is returned to purchase another bond that meets the investment objectives of the fund. So the fund never matures, since it is always investing in more bonds when the old ones mature. Unit investment trusts made of bonds do have a maturity date as well, since the portfolio does not change once the UIT is issued. As the individual bonds in the portfolio mature, the principle value is returned to investors. So the overall maturity date is effectively the maturity date of the last bond in the trust. All of the statements quoted above are accurate in explaining why there is no guarantee of a return of principle when investing in bond funds (ETF or open-ended mutual fund). The bonds they hold do mature, but are replaced within the fund as needed. The investor will never see it happen unless they watch the holdings reports filed by the funds.  The only way to have an assurance of the return of principle is to invest in individual bonds, or in unit trusts made up of bonds. There are not necessarily large shareholders, maybe every other Joe Schmoe owns 3 or 5 shares; and many shares might be inside investment funds. If you are looking for voting rights, typically, the banks/investment companies that host the accounts of the individual shareholders/fund owners have the collective voting rights, so the Fidelity's and Vanguard's of the world will be the main and deciding voters. That is very common. "Most mutual funds are designed to make the investment banks that sell them money, not to make investers money. They do this by taking significant fees out. Because they make lots of money on these funds, they advertise them a lot, and give them important-sounding names, like ""Advanced technology global diversity long term appreciation"".  Index funds are the exception; they attempt to mirror the performance of a specific index (such as the S&P 500 index). They generally have very low fees."
