Getting started in stock with one special field of activity
I don't think investing in only one industry, which you may know well, is very wise. You may want to invest in that industry but you should not restrict yourself from investing solely in that industry.  There are many times when your chosen industry may not be performing very well and other industries are performing much better. If you restrict yourself to just one industry you may be either out of the market for long periods of time or your portfolio may show negative returns for extended periods of time. You may want to know an industry or a number of companies very well but do not fall in love with them. The worst thing you can do is get emotional about an investment, an investment is there to make you money not for you to get emotional about. Don't restrict yourself, instead look to maximise your returns with investments that are performing better at the time. Investing only in one industry may be problematic as it is highly correlated. There are factor outside your (or anyones) knowledge which may affect all the industry: If you are familiar with the industry it may happen that you work in that (ignore rest of paragraph if this is not the case). In such case you are likely to have problems at work (frozen salary, no bonus, position terminated) and you need to liquidate the investments at that point (see many advice regarding ESPP). Depending on your field you may have some inside knowledge so even if you would took a position without it you may need to somehow prove it. On the other hand diversifying the investment might reduce the volatility of investment. Rise in oil will cause problems for air industry but will be a boom for oil industry etc. In this way you smooth the grow of the investments. Investing part of portfolio into specific industry may make more sense. It still possibly worth to avoid it at the beginning investor may have trouble to beat the market (for example according to behavioural economics you are exposed to various biases, or if markets are efficient then prices most likely already take into account any information you may have). (I'm still new to all this so it's mostly based on what I read rather then any personal experience. Also a standard disclaimer that this is not an investment, or any other, advice and I'm not licensed financial advisor in any jurisdiction) You are always best off investing in things you understand. If you have a deep understanding of the aeronautical industry, say, you are a Vice President at Boeing and have been working at Boeing for 40 years, then that would be a reason for investing in that sector: because you may be able to better evaluate different companies in that sector. If you are a novice in the sector, or just have an amateur interest in it, then it may not be a good idea, because your knowledge may not be sufficient to give you much of an advantage. Before focusing on one investment of any type, industry sector based, or otherwise, you want to ask yourself: am I an expert in this subject? The answer to that question will have a big impact on your success. "It depends on what you're talking about. If this is for your retirement accounts, like IRAs, then ABSOLUTELY NOT! In your retirement accounts you should be broadly diversified - not just between stocks, but also other markets like bonds. Target retirement funds and solid conservative or moderate allocation funds are the best 'quick-and-dirty' recommendation for those accounts. Since it's for the long haul, you want to be managing risk, not chasing returns. Returns will happen over the 40 or so years they have to grow.  Now, if you're talking about a taxable stock account, and you've gotten past PF questions like ""am I saving enough for retirement"", and ""have I paid off my debt"", then the question becomes a little more murky.  First, yes, you should be diversified. The bulk of how a stock's movement will be in keeping with how its sector moves; so even a really great stock can get creamed if its sector is going down. Diversification between several sectors will help balance that.  However, you will have some advantage in this sector. Knowing which products are good, which products everybody in the industry is excited about, is a huge advantage over other investors. It'll help you pick the ones that go up more when the sector goes up, and down less when the sector goes down. That, over time and investments, really adds up. Just remember that a good company and a good stock investment are not the same thing. A great company can have a sky-high valuation -- and if you buy it at that price, you can sit there and watch your investment sink even as the company is growing and doing great things. Have patience, know which companies are good and which are bad, and wait for the price to come to you.  One final note: it also depends on what spot you are in. If you're a young guy looking looking to invest his first few thousand in the market, then go for it. On the other hand, if you're older, and we're talking about a couple hundred grand you've got saved up, then it's a whole different ball of wax. It that spot, you're back to managing risk, and need to build a solid portfolio, at a measured pace."
I have heard of this, but then the broker is short the shares if they weren't selling them out of inventory, so they still want to accumulate the shares or a hedge before EOD most likely - In that case it may not be the client themselves, but that demand is hitting the market at some point if there isn't sufficient selling volume.    Whether or not the broker ends up getting all of them below VWAP is a cost of marketing for them, how they expect to reliably get real size below vwap is my question. There is none, whatever sector you invest in will be subject to cyclical market difficulties, however alpha can be generated from two sources: Timing and selection.  Its much easier to get the timing done over a long period of time. "I'll skip the ""authorizing...."" and go right to uses of new shares: Companies need stock as another liquid asset for a variety of purposes, and if not enough stock is available, then may be forced to the open market to acquire, either by exchanging cash or taking on debt to get the cash." Yes, you can do this buy placing a conditional order to buy at market if the price moves to 106 or above. Once the price hits 106 your market order will hit the market and you will purchase the stock at 106 or above. You can also place a tack profit order at 107 linked to your initial conditional buy order, so that once you buy order is executed and you buy at 106, a take profit order will be executed only if the price reaches 107 or above.  If the price never reaches 106, neither your market buy order or take profit order will hit the market and you won't buy or sell anything. You can also use ICS&lt;GO&gt; on Bloomberg and choose the right category (many subcategories, probably you'll start on home builders or something like that). If that doesn't work, press F1 twice and ask it to an analyst. I'm sure they have this info. "You can place the orders like you suggested.  This would be useful in a market that is moving quickly where you want to be reasonably sure of execution but don't want the full exposure of a market order.  This won't jump your spot in the queue though in the sense that you won't get ahead of other orders that are ""ready"" for execution just because you have crossed the spread aggressively." 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. "It is possible and it depends on your strategy. As short selling interest rates are annual and levied monthly at a prorated rate. Interest rates are also low in general, with the exception of hard to borrow stocks. Therefore you can maintain a short position for weeks on end and notice nothing. Months even, if the position itself has already gained in your favor. There is no additional fee for opening the short position. Although some brokers have a ""locate"" fee, if it is hard to borrow the stock and they need to go find some shares to short. So you can do it as much as you like." thanks for the advice, I still have few weeks before my master course starts and would like to do more reading regarding trading, any books that you would recommend ?   Also I always assume that modelling skill is not that important in sales and trading, is my assumption correct ? Modelling is probably one of my weak skills but if it is needed I would like to work further on it   thank you As BobbyScon said in the comments, invest in a company that is developing in that field. Or invest in a company which supplies that field. The people who got rich in the California gold rush were those selling shovels and other miners' supplies. Or bet against whatever you think this will displace. If automobiles are the hot new thing, it might be a bad time to invest in harness leather. Or ... figure out how else it might impact the economy and invest appropriately. But you have to do that evaluation yourself. Or ignore it and stick with your existing strategy, which should have been diversified enough to deliver reasonable results whether this sector takes off or not. Remember that if someone gives you a free tip, they are probably just hoping to pump up the value of their own stock rather than help you. "(Note: out of my depth here, but in case this helps...) While not a direct answer to your question, I'll point out that in the inverse situation - a U.S. investor who wants to buy individual stocks of companies headquartered outside US - you would buy ADRs, which are $-denominated ""wrapper"" stocks.  They can be listed with one or multiple brokerages. One alternative I'd offer the person in my example would be, ""Are you really sure you want to directly buy individual stocks?""  One less targeted approach available in the US is to buy ETFs targeted for a given country (or region).   Maybe there's something similar there in Asia that would eliminate the (somewhat) higher fees associated with trading foreign stocks." Well, Taking a short position directly in real estate is impossible because it's not a fungible asset, so the only way to do it is to trade in its derivatives - Investment Fund Stock, indexes and commodities correlated to the real estate market (for example, materials related to construction).    It's hard to find those because real estate funds usually don't issue securities and rely on investment made directly with them. Another factor should be that those who actually do have issued securities aren't usually popular enough for dealers and Market Makers to invest in it, who make it possible to take a short position in exchange for some spread. So what you can do is, you can go through all the existing real estate funds and find out if any of them has a broker that let's you short it, in other words which one of them has securities in the financial market you can buy or sell. One other option is looking for real estate/property derivatives, like this particular example. Personally, I would try to computationally find other securities that may in some way correlate with the real estate market, even if they look a bit far fetched to be related like commodities and stock from companies in construction and real estate management, etc. and trade those because these have in most of the cases more liquidity. Hope this answers your question! No. Supply takes 5yrs to come on line from planting to harvesting. The issue on the supply side has been twofold: 1) vanilla bean prices have been falling for some time so many farmers switched to other crops, 2) 50%+ of all vanilla bean is grown in Madasgar, which experienced a typhoon, which damaged a bunch of the existing crop. On the demand side, people are switching from artificial flavoring to more natural ingredients, which actually taste much better too.    So, there's a significant demand/supply imbalance which will utilitmately correct but it could take a long time to do so.   My problem is figuring out a viable shorting mechanism as the commodity is not publicly traded and the timeframe is long You should. The impact on the credit score is small, and probably not worth the money of the annual fee. I would only change that if you plan to get a mortgage or car loan the next month - then wait until afterwards. "For most situations the ""no need"" answers are 100% correct. The corner case to think about depends on your health and your family history.  Not to be morose, but if folks in your family who died young from heart issues, clusters of cancer or other terminal illnesses, you may want to consider getting medically qualified for a modest amount of insurance when you are young. Then, when you have children, you usually have the option of incrementally upgrading your coverage over time."
