Is stock in a company considered a good or a service, or something else?
Well it depends on whether or not your differentiating against. If its capital stock or stock as in a share certificate in the company. If its a share in the company then in my opinion using Equity would be best as it is a form of an asset and does refer to a piece of ownership of the entity. I wouldn't consider a share of stock a service, since the service to you is say Facebook or the broker who facilitates the transaction of buying or selling FB stock. I also would not consider it a Capital Good, as the Capital Good's would be the referring to the actual capital like the servers,other computer equipments etc. Facebook the company is probably better understood as a capital good - it is a collection of software and servers and a well-known brand name with a snazzy network effect under reasonably competent corporate governance that can produce final goods and services (mostly services) that actually have value. A share of Facebook stock is a share of ownership in that capital. See also: http://en.wikipedia.org/wiki/Capital_good which makes some concessions for the difference between capital goods and capital services, so it's kind of a fuzzy thing. Stock is ownership. And whether the thing you own is a good or service irrelevant. The ownership itself is all that matters. Ownership = service ??? Ownership = good ??? Maybe the problem is your trying to fit a verb into a noun-based categories?
"As I stated in my comment, options are futures, but with the twist that you're allowed to say no to the agreed-on transaction; if the market offers you a better deal on whatever you had contracted to buy or sell, you have the option of simply letting it expire. Options therefore are the insurance policy of the free market. You negotiate a future price (actually you usually take what you can get if you're an individual investor; the institutional fund managers get to negotiate because they're moving billions around every day), then you pay the other guy up front for the right of refusal later. How much you pay depends on how likely the person giving you this option is to have to make good on it; if your position looks like a sure thing, an option's going to be very expensive (and if it's such a sure thing, you should just make your move on the spot market; it's thus useful to track futures prices to see where the various big players are predicting that your portfolio will move). A put option, which is an option for you to sell something at a future price, is a hedge against loss of value of your portfolio. You can take one out on any single item in your portfolio, or against a portion or even your entire portfolio. If the stock loses value such that the contract price is better than the market price as of the delivery date of the contract, you execute the option; otherwise, you let it expire. A call option, which is an option to buy something at a future price, is a hedge against rising costs. The rough analog is a ""pre-order"" in retail (but more like a ""holding fee""). They're unusual in portfolio management but can be useful when moving money around in more complex ways. Basically, if you need to guarantee that you will not pay more than a certain per-share price to buy something in the future, you buy a call option. If the spot price as of the delivery date is less than the contract price, you buy from the market and ignore the contract, while if prices have soared, you exercise it and get the lower contract price. Stock options, offered as benefits in many companies, are a specific form of call option with very generous terms for whomever holds them. A swaption, basically a put and a call rolled into one, allows you to trade something for something else. Call it the free market's ""exchange policy"". For a price, if a security you currently hold loses value, you can exchange it for something else that you predicted would become more valuable at the same time. One example might be airline stocks and crude oil; when crude spikes, airline stocks generally suffer, and you can take advantage of this, if it happens, with a swaption to sell your airline stocks for crude oil certificates. There are many such closely-related inverse positions in the market, such as between various currencies, between stocks and commodities (gold is inversely related to pretty much everything else), and even straight-up cash-for-bad-debt arrangements (credit-default swaps, which we heard so much about in 2008)." "The game is not zero sum. When a friend and I chop down a tree, and build a house from it, the house has value, far greater than the value of a standing tree. Our labor has turned into something of value.  In theory, a company starts from an idea, and offers either a good or service to create value. There are scams that make it seem like a Vegas casino. There are times a stock will trade for well above what it should. When I buy the S&P index at a fair price for 1000 (through an etf or fund) and years later it's 1400, the gain isn't out of someone else's pocket, else the amount of wealth in the world would be fixed and that's not the case. Over time, investors lag the market return for multiple reasons, trading costs, bad timing, etc. Statements such as ""90% lose money"" are hyperbole meant to separate you from your money. A self fulfilling prophesy.   The question of lagging the market is another story - I have no data to support my observation, but I'd imagine that well over 90% lag the broad market. A detailed explanation is too long for this forum, but simply put, there are trading costs. If I invest in an S&P ETF that costs .1% per year, I'll see a return of say 9.9% over decades if the market return is 10%. Over 40 years, this is 4364% compounded, vs the index 4526% compounded, a difference of less than 4% in final wealth. There are load funds that charge more than this just to buy in (5% anyone?).  Lagging by a small fraction is a far cry from 'losing money.'  There is an annual report by a company named Dalbar that tracks investor performance. For the 20 year period ending 12/31/10 the S&P returned 9.14% and Dalbar calculates the average investor had an average return of 3.83%. Pretty bad, but not zero. Since you don't cite a particular article or source, there may be more to the story. Day traders are likely to lose. As are a series of other types of traders in other markets, Forex for one.  While your question may be interesting, its premise of ""many experts say...."" without naming even one leaves room for doubt.  Note - I've updated the link for the 2015 report. And 4 years later, I see that when searching on that 90% statistic, the articles are about day traders. That actually makes sense to me." "Index funds can be a very good way to get into the stock market. It's a lot easier, and cheaper, to buy a few shares of an index fund than it is to buy a few shares in hundreds of different companies. An index fund will also generally charge lower fees than an ""actively managed"" mutual fund, where the manager tries to pick which stocks to invest for you. While the actively managed fund might give you better returns (by investing in good companies instead of every company in the index) that doesn't always work out, and the fees can eat away at that advantage. (Stocks, on average, are expected to yield an annual return of 4%, after inflation. Consider that when you see an expense ratio of 1%. Index funds should charge you more like 0.1%-0.3% or so, possibly more if it's an exotic index.) The question is what sort of index you're going to invest in. The Standard and Poor's 500 (S&P 500) is a major index, and if you see someone talking about the performance of a mutual fund or investment strategy, there's a good chance they'll compare it to the return of the S&P 500. Moreover, there are a variety of index funds and exchange-traded funds that offer very good expense ratios (e.g. Vanguard's ETF charges ~0.06%, very cheap!). You can also find some funds which try to get you exposure to the entire world stock market, e.g. Vanguard Total World Stock ETF, NYSE:VT). An index fund is probably the ideal way to start a portfolio - easy, and you get a lot of diversification. Later, when you have more money available, you can consider adding individual stocks or investing in specific sectors or regions. (Someone else suggested Brazil/Russia/Indo-China, or BRICs - having some money invested in that region isn't necessarily a bad idea, but putting all or most of your money in that region would be. If BRICs are more of your portfolio then they are of the world economy, your portfolio isn't balanced. Also, while these countries are experiencing a lot of economic growth, that doesn't always mean that the companies that you own stock in are the ones which will benefit; small businesses and new ventures may make up a significant part of that growth.) Bond funds are useful when you want to diversify your portfolio so that it's not all stocks. There's a bunch of portfolio theory built around asset allocation strategies. The idea is that you should try to maintain a target mix of assets, whatever the market's doing. The basic simplified guideline about investing for retirement says that your portfolio should have (your age)% in bonds (e.g. a 30-year-old should have 30% in bonds, a 50-year-old 50%.) This helps maintain a balance between the volatility of your portfolio (the stock market's ups and downs) and the rate of return: you want to earn money when you can, but when it's almost time to spend it, you don't want a sudden stock market crash to wipe it all out. Bonds help preserve that value (but don't have as nice of a return). The other idea behind asset allocation is that if the market changes - e.g. your stocks go up a lot while your bonds stagnate - you rebalance and buy more bonds. If the stock market subsequently crashes, you move some of your bond money back into stocks. This basically means that you buy low and sell high, just by maintaining your asset allocation. This is generally more reliable than trying to ""time the market"" and move into an asset class before it goes up (and move out before it goes down). Market-timing is just speculation. You get better returns if you guess right, but you get worse returns if you guess wrong. Commodity funds are useful as another way to diversify your portfolio, and can serve as a little bit of protection in case of crisis or inflation. You can buy gold, silver, platinum and palladium ETFs on the stock exchanges. Having a small amount of money in these funds isn't a bad idea, but commodities can be subject to violent price swings! Moreover, a bar of gold doesn't really earn any money (and owning a share of a precious-metals ETF will incur administrative, storage, and insurance costs to boot). A well-run business does earn money. Assuming you're saving for the long haul (retirement or something several decades off) my suggestion for you would be to start by investing most of your money* in index funds to match the total world stock market (with something like the aforementioned NYSE:VT, for instance), a small portion in bonds, and a smaller portion in commodity funds. (For all the negative stuff I've said about market-timing, it's pretty clear that the bond market is very expensive right now, and so are the commodities!) Then, as you do additional research and determine what sort investments are right for you, add new investment money in the places that you think are appropriate - stock funds, bond funds, commodity funds, individual stocks, sector-specific funds, actively managed mutual funds, et cetera - and try to maintain a reasonable asset allocation. Have fun. *(Most of your investment money. You should have a separate fund for emergencies, and don't invest money in stocks if you know you're going need it within the next few years)." "This question was asked over at wilmott.com which is a site for quantitative analysts. Some of the finest minds in the business (I am serious here) pondered the question. the best answer was along the lines of: ""A Gambler generally gambles their own money, a derivatives trader gambles using someone else's"".  There is an important legal difference is that a gambling dept is normally considered a ""debt of honor"", that is not enforceable in a court of law whilst a derivatives contract is considered legally binding. This last bit gets a bit interesting under some jurisdictions because only derivatives contracts involving the delivery of something physical are enforceable, whilst contracts involving settlement with financial instruments are not, so a stock index future would not be recognized." Typically a private company is hit by demand supply issues and cost of inputs. In effect at times the cost of input may go up, it cannot raise the prices, because this will reduce demand. However certain public sectors companies, typically in Oil & Engery segements the services are offered by Public sector companies, and the price they charge is governed by Regulatory authorities. In essence the PG&E, the agreement for price to customers would be calculated as cost of inputs to PG&E, Plus Expenses Plus 11.35% Profit. Thus the regulated price itself governs that the company makes atleast 11.35% profit year on year. Does this mean that the shares are good buy?  Just to give an example, say the price was $100 at face value, So essentially by year end logically you would have made 111.35/-. Assuming the company did not pay dividend ... Now lets say you began trading this share, there would be quite a few people who would say I am ready to pay $200 and even if I get 11.35 [on 200] it still means I have got ~6% return. Someone may be ready to pay $400, it still gives ~3% ... So in short the price of the stock would keep changing depending how the market percieves the value that a company would return. If the markets are down or the sentiments are down on energy sectors, the prices would go down.  So investing in PG&E is not a sure shot way of making money. For actual returns over the years see the graph at http://www.pgecorp.com/investors/financial_reports/annual_report_proxy_statement/ar_html/2011/index.htm#CS It's 5% free money, if you believe the company's stock is fairly valued and likely to grow and/or return reasonable dividends until you're ready to sell it. There's usually a minimum holding period of a few months to a year before these discounted shares can be sold; take that into account Would you consider the owner of a company to be supporting the company? If you buy stock in the company you own a small part of that company. Your purchase also increases the share price, and thus the value of the company. Increased value allows the company to borrow more money to say expand operations. The affect that most individuals might have on share price is very very small. That doesn't mean it isn't the right thing for you to do if it is something you believe in. After all if enough people followed those same convictions it could have an impact on the company. Employee Stock Purchase Plans (ESPPs) were heavily neutered by U.S. tax laws a few years ago, and many companies have cut them way back. While discounts of 15% were common a decade ago, now a company can only offer negligible discounts of 5% or less (tax free), and you can just as easily get that from fluctuations in the market. These are the features to look for to determine if the ESPP is even worth the effort: As for a cash value, if a plan has at least one of those features, (and you believe the stock has real long term value), you still have to determine how much of your money you can afford to divert into stock. If the discount is 5%, the company is paying you an extra 5% on the money you put into the plan.
