Last trade is bought? or sold?
"When there is a trade the shares were both bought and sold. In any trade on the secondary market there has to be both a buyer and a seller for the trade to take place. So in ""lasttradesize"" a buyer has bought the shares from a seller."
"For the future: NEVER buy a car based on the payment.  When dealers start negotiating, they always try to have you focus on the monthly payment.  This allows them to change the numbers for your trade, the price they are selling the car for, etc so that they maximize the amount of money they can get.  To combat this you need to educate yourself on how much total money you are willing to spend for the vehicle, then, if you need financing, figure out what that actually works out to on a monthly basis. NEVER take out a 6 year loan.  Especially on a used car.  If you can't afford a used car with at most a 3 year note (paying cash is much better) then you can't really afford that car.  The longer the note term, the more money you are throwing away in interest.  You could have simply bought a much cheaper car, drove it for a couple years, then paid CASH for a new(er) one with the money you saved.   Now, as to the amount you are ""upside down"" and that you are looking at new cars.  $1400 isn't really that bad.  (note: Yes you were taken to the cleaners.)  Someone mentioned that banks will sometimes loan up to 20% above MSRP.  This is true depending on your credit, but it's a very bad idea because you are purposely putting yourself in the exact same position (worse actually).   However, you shouldn't need to worry about that.  It is trivial to negotiate such that you pay less than sticker for a new car while trading yours in, even with that deficit.  Markup on vehicles is pretty insane.  When I sold, it was usually around 20% for foreign and up to 30% for domestic: that leaves a lot of wiggle room. When buying a used car, most dealers ask for at least $3k more than what they bought them for... Sometimes much more than that depending on blue book (loan) value or what they managed to talk the previous owner out of.   Either way, a purchase can swallow that $1400 without making it worse.  Buy accordingly." "At the most fundamental level, every market is comprised of buyers and selling trading securities. These buyers and sellers decide what and how to trade based on the probability of future events, as they see it. That's a simple statement, but an example demonstrates how complicated it can be. Picture a company that's about to announce earnings. Some investors/traders (from here on, ""agents"") will have purchased the company's stock a while ago, with the expectation that the company will have strong earnings and grow going forward. Other agents will have sold the stock short, bought put options, etc. with the expectation that the company won't do as well in the future. Still others may be unsure about the future of the company, but still expecting a lot of volatility around the earnings announcement, so they'll have bought/sold the stock, options, futures, etc. to take advantage of that volatility.  All of these various predictions, expectations, etc. factor into what agents are bidding and asking for the stock, its associated derivatives, and other securities, which in turn determines its price (along with overall economic factors, like the sector's performance, interest rates, etc.) It can be very difficult to determine exactly how markets are factoring in information about an event, though. Take the example in your question. The article states that if market expectations of higher interest rates tightened credit conditions... In this case, lenders could expect higher interest rates in the future, so they may be less willing to lend money now because they expect to earn a higher interest rate in the future. You could also see this reflected in bond prices, because since interest rates are inversely related to bond prices, higher interest rates could decrease the value of bond portfolios. This could lead agents to sell bonds now in order to lock in their profits, while other agents could wait to buy bonds because they expect to be able to purchase bonds with a higher rate in the future.  Furthermore, higher interest rates make taking out loans more expensive for individuals and businesses. This potential decline in investment could lead to decreased revenue/profits for businesses, which could in turn cause declines in the stock market. Agents expecting these declines could sell now in order to lock in their profits, buy derivatives to hedge against or ride out possible declines, etc. However, the current low interest rate environment makes it cheaper for businesses to obtain loans, which can in turn drive investment and lead to increases in the stock market. This is one criticism of the easy money/quantitative easing policies of the US Federal Reserve, i.e. the low interest rates are driving a bubble in the stock market. One quick example of how tricky this can be. The usual assumption is that positive economic news, e.g. low unemployment numbers, strong business/residential investment, etc. will lead to price increases in the stock market as more agents see growth in the future and buy accordingly. However, in the US, positive economic news has recently led to declines in the market because agents are worried that positive news will lead the Federal Reserve to taper/stop quantitative easing sooner rather than later, thus ending the low interest rate environment and possibly tampering growth.  Summary: In short, markets incorporate information about an event because the buyers and sellers trade securities based on the likelihood of that event, its possible effects, and the behavior of other buyers and sellers as they react to the same information. Information may lead agents to buy and sell in multiple markets, e.g. equity and fixed-income, different types of derivatives, etc. which can in turn affect prices and yields throughout numerous markets." The preparation for starting up of the company has lasted already more than 2 years. Let's say the company starts officially in January next year. So, in January 2014... 8 million USD is invested to purchase the equipments and the company will start selling their prdocuts right away. Imagine the company will be selling the same amount of products each year at the same price for 5 years. After 5 years it will sell the equipments for 6 million USD and cease to exist. The depreciation of  equipments is divided into those 5 years. So, each year the depreciation of equipments is 400.000 USD. In despite of this, the company will make 500.000 USD per year as a profit before tax.  So, the equipments are bought in Januardy 2014 (first month of the existence of the company) and sold in December 2018 (last month of the existence of the company). This is the NPV that I calculated. Is it correct? I don't see a tag for United States, so I'm having to assume this is US taxes.  It doesn't matter what app you use, IRS trades are all calculated the same. First, you have to report each trade on a 8949 and from that the totals go into a schedule D.  Short term trades are stocks that you've kept exactly one year or less, long term trades are for 1 year + 1 day or more.  Trades where you sold a stock for a loss, then bought that stock back again under 30 days don't get to count as a loss.  This only affects realized capital gains and losses, you don't count fees. First, take all of your short term gains then offset them by all of your short term losses.  Do the same for long term gains and losses.  Short and long term gains are taxed at different rates.  You can deduct losses from short term to your long term and vice versa.  Then you can deduct the total losses up to $3000 (household, $1500 married, filing separately) per year on your regular income taxes or other dividend taxes.  If you have over $3000 in losses, then you need to carry that over to subsequent years. Edited per Dave's comments: thanks Dave "This answer relies on why you are holding shares of a company in the first place. So let's address that: So does this mean you would like to vote with your shares on the directions the company takes? If so, your reasons for selling would be different from the next speculator who only is interested in share price volatility. Regardless of your participation in potential voting rights associated with your share ownership, a different reason to sell is based on if your fundamental reasons for investing in the company have changed.  Enhancements on this topic include: Trade management, how to deal with position sizes. Buying and selling partial positions based on price action while keeping a core long term position, but this is not something ""long term investors"" generally put too much effort in. Price targets, start your long term investment with a price target in mind, derived from a future market cap based on your initial fundamental analysis of the company's prospects. And finally, there are a lot of things you can do with a profitable investment in shares." The two answers so far are right, but there's a third factor - for many stocks, there's after hours trading. So the official 4PM close is not what the stock's last trade was when they open again. Regardless, even that after hour price is not the starting point as Muro points out. "Since doodle77 handled arbitrage, I'll take goodwill.  Goodwill is an accounting term that acts much like a ""plug"" account: you add/subtract to it the amount that makes everything balance.  In the case of goodwill, it generally only applies to mergers &amp; acquisitions.  The theory (and justification) is this: firms buy other firms at prices other than the market price (usually higher), and it is assumed that this is because the acquirer values its acquisition more than other people do.  But whether you use historical prices or market prices when you add (subtract) assets and liabilities to to (from) your balance sheet, this will never add up, because you paid more (less) than the assets are worth in the market, so more (less) cash flowed out than assets flowed in.  The difference goes into the goodwill account, so firms with a large goodwill account are ones that have made lots of acquisitions." "Why would there not be a bid and ask?  Dealers make their money in the spread between what they buy it from one entity for and what they sell it to another entity for.  This doesn't mean they have to do it auction-style, but they'll still have a different buy price from a sell price, hence ""bid"" and ""ask""."
