Why most of apple stock price since 10years have been gained overnight?
"I'll answer this question: ""Why do intraday traders close their position at then end of day while most gains can be done overnight (buy just before the market close and sell just after it opens). Is this observation true for other companies or is it specific to apple ?"" Intraday traders often trade shares of a company using intraday leverage provided by their firm. For every $5000 dollars they actually have, they may be trading with $100,000, 20:1 leverage as an example. Since a stock can also decrease in value, substantially, while the markets are closed, intraday traders are not allowed to keep their highly leveraged positions opened. Probabilities fail in a random walk scenario, and only one failure can bankrupt you and the firm."
"Ex-Apple Store employee here. I didn't read the article, but then again I didn't need to. Apple is a great company, blah blah blah. Here's the bottom line: If I sell $15,000 of computers in 6 hours (something that's not so terribly hard to do), I still get paid the same $11.5/hr. Why the fuck should I work harder to sell? Pressure from above. Also they print a list of how much everyone has sold by day, week, month, quarter and YTD. You want to be in the top 5 of that list.  Now, I worked there from 2008-2010, so things could be a lot different there now. But I suspect they're not. There's a huge amount of churn, as someone said, and I'd argue that it is entirely to keep happy smiling dumb faces there all the time. The ""Lifers"" are huge tools who suck big ones.   I still love Apple. Just glad I don't work for them." It's important to note that this 10% share price drop comes after a year in which Best Buy's stock price has risen more than 50%.   It's done this by focussing on matching Amazon's prices while providing better human-to-human customer service.  https://www.nytimes.com/2017/09/18/business/best-buy-amazon.html "In addition to the answers provided above, the weight the Dow uses to determine the index is not the market capitalization of the company involved. That means that companies like Google and Apple with very high share prices and no particular inclination to split could adversely effect the Dow, turning it into essentially the ""Apple and Google and then some other companies"" Industrial Average. The highest share price Dow company right now, IIRC, is IBM. Both Google and Apple would have three times the influence on the Index as IBM does now." In an ideal world Say on 24th July the share price of Apple was $600. Everyone knows that they will get the $ 2.65 on 16th August. There is not other news that is affecting the price. You want to go in and buy the shares on 16th Morning at $600 and then sell it on 17th August at $600. Now in this process you have earned sure shot $2.65/- Or in an ideal world when the announcement is made on 24th July, why would I sell it at $600, when I know if I wait for few more days I will get $2.65/- so i will be more inclined to sell it at $602.65 /- ... so on 16th Aug after the dividend is paid out, the share price will be back to $600/- In a real world, dividend or no dividend the share price would be moving up or down ... Notice that the dividend amount is less than 1% of the stock price ... stock prices change more than this percentage ... so if you are trying to do what is described in paragraph one, then you may be disappointed as the share price may go down as well by more than $2.65 you have made Intuitive? I doubt it. Derivatives are not the simplest thing to understand.  The price is either in the money or it isn't. (by the way, exactly 'at the money' is not 'in the money.') An option that's not in the money has time value only. As the price rises, and the option is more and more in the money, the time value drops. We have a $40 stock. It makes sense to me that a $40 strike price is all just a bet the stock will rise, there's no intrinsic value. The option prices at about $4.00 for one year out, with 25% volatility. But the strike of $30 is at $10.68, with $10 in the money and only .68 in time premium. There's a great calculator on line to tinker with.  Volatility is a key component of options trading. Think about it. If a stock rises 5%/yr but rarely goes up any more or less, just steady up, why would you even buy an option that was even 10% out of the money? The only way I can describe this is to look at a bell curve and how there's a 1/6 chance the event will be above one standard deviation. If that standard deviation is small, the chance of hitting the higher strikes is also small.  I wrote an article Betting on Apple at 9 to 2 in which I describe how a pair of option trades was set up so that a 35% rise in Apple stock would return 354% and Apple had two years to reach its target. I offer this as an example of options trading not being theory, but something that many are engaged in. What I found curious about the trade was that Apple's volatility was high enough that a 35% move didn't seem like the 4.5 to 1 risk the market said it was. As of today, Apple needs to rise 13% in the next 10 months for the trade to pay off. (Disclosure - the long time to expiration was both good and bad, two years to recover 35% seemed reasonable, but 2 years could bring anything in the macro sense. Another recession, some worldwide event that would impact Apple's market, etc. The average investor will not have the patience for these long term option trades.) "The Dow Jones Industrial Average (DJIA) is a Price-weighted index.  That means that the index is calculated by adding up the prices of the constituent stocks and dividing by a constant, the ""Dow divisor"".  (The value of the Dow divisor is adjusted from time to time to maintain continuity when there are splits or changes in the roster.)  This has the curious effect of giving a member of the index influence proportional to its share price.  That is, if a stock costing $100 per share goes up by 1%, that will change the index by 10 times as much as if a stock costing $10 per share goes up by the same 1%. Now look at the price of Google.  It's currently trading at just a whisker under $700 per share.  Most of the other stocks in the index trade somewhere between $30 and $150, so if Google were included in the index it would contribute between 5 and 20 times the weight of any other stock in the index.  That means that relatively small blips in Google's price would completely dominate the index on any given day.  Until June of 2014, Apple was in the same boat, with its stock trading at about $700 per share.  At that time, Apple split its stock 7:1, and after that its stock price was a little under $100 per share.  So, post-split Apple might be a candidate to be included in the Dow the next time they change up the components of the index.  Since the Dow is fixed at 30 stocks, and since they try to keep a balance between different sectors, this probably wouldn't happen until they drop another technology company from the lineup for some reason.  (Correction: Apple is in the DJIA and has been for a little over a year now.  Mea culpa.) The Dow's price-weighting is unusual as stock indices go.  Most indices are weighted by market capitalization.  That means the influence of a single company is proportional to its total value.  This causes large companies like Apple to have a lot of influence on those indices, but since market capitalization isn't as arbitrary as stock price, most people see that as ok.  Also, notice that I said ""company"" and not ""stock"".  When a company has multiple classes of share (as Google does), market-cap-weighted indices include all of the share classes, while the Dow has no provision for such situations, which is another, albeit less important, reason why Google isn't in the Dow.  (Keep this in mind the next time someone offers you a bar bet on how many stocks are in the S&P 500.  The answer is (currently) 505!) Finally, you might be wondering why the Dow uses such an odd weighting in its calculations.  The answer is that the Dow averages go back to 1896, when Charles Dow used to calculate the averages by hand.  If your only tools are a pencil and paper, then a price-weighted index with only 30 stocks in it is a lot easier to calculate than a market-cap-weighted index with hundreds of constituents.

(Note that prices before the split are retroactively adjusted to show a continuous curve.)" "What most of these answers here seem to be missing is that a stock ""price"" is not exactly what we typically expect a price to be--for example, when we go in to the supermarket and see that the price of a gallon of milk is $2.00, we know that when we go to the cash register that is exactly how much we will pay.  This is not, however, the case for stocks. For stocks, when most people talk about the price or quote, they are really referring to the last price at which that stock traded--which unlike for a gallon of milk at the supermarket, is no guarantee of what the next stock price will be.  Relatively speaking, most stocks are extremely liquid, so they will react to any information which the ""market"" believes has a bearing on the value of their underlying asset almost (if not) immediately.  As an extreme example, if allegations of accounting fraud for a particular company whose stock is trading at $40 come out mid-session, there will not be a gradual decline in the price ($40 -> $39.99 -> $39.97, etc.)-- instead, the price will jump from $40 to say, $20.  In the time between the the $40 trade and the $20 trade, even though we may say the price of the stock was $40, that quote was actually a terrible estimate of the stock's current (post-fraud announcement) price. Considering that the ""price"" of a stock typically does not remain constant even in the span of a few seconds to a few minutes, it should not be hard to believe that this price will not remain constant over the 17.5 hour period from the previous day's close to the current day's open.  Don't forget that as Americans go to bed, the Asian markets are just opening, and by the time US markets have opened, it is already past 2PM in London.  In addition to the information (and therefore new knowledge) gained from these foreign markets' movements, macro factors can also play an important part in a security's price-- perhaps the ECB makes a morning statement that is interpreted as negative news for the markets or a foreign government before the US markets open.  Stock prices on the NYSE, NASDAQ, etc. won't be able to react until 9:30, but the $40 price of the last trade of a broad market ETF at 4PM yesterday probably isn't looking so hot at 6:30 this morning... don't forget either that most individual stocks are correlated with the movement of the broader market, so even news that is not specific to a given security will in all likelihood still have an impact on that security's price. The above are only a few of many examples of things that can impact a stock's valuation between close and open: all sorts of geopolitical events, announcements from large, multi-national companies, macroeconomic stats such as unemployment rates, etc. announced in foreign countries can all play a role in affecting a security's price overnight. As an aside, one of the answers mentioned after hours trading as a reason--in actuality this typically has very little (if any) impact on the next day's prices and is often referred to as ""amateur hour"", due to the fact that trading during this time typically consists of small-time investors.  Prices in AH are very poor predictors of a stock's price at open." Their argument is mostly nonsense. Take someone like Tim Cook, CEO of Apple. He has a not very large salary, and makes a lot more money through stock bonuses. You would never, ever expect him to buy Apple shares. And assuming that he doesn't want to end up one day as the richest man in the cemetery, you would expect him to sell significant numbers of shares, independent on whether he expects Apple to go up or down. You could try to refine your options strategy:  For instance you could buy the USD 750 call option(s) you mentioned and at the same time sell (short) call options with a higher strike price, which is above the share price level you expect that Apple will trade at in one year (for instance USD 1,100).  By doing this, you would receive the premium of the call option(s) with the higher option, which in turn would help you finance buying your USD 750 call(s). The net effect of this trading strategy would be that you would give up the extra profit you would earn if Apple would rose above USD 1,100 (the strike price of the call option sold short). Your total risk would be even less than with your actual strategy (in my view). There's a case to be made that companies below a certain market cap have more potential than the higher ones.  Consider, Apple cannot grow 100 fold from its current value. At $700B or so in value, that would be a $70T goal, just about the value of all the combined wealth in the entire US. At some point, the laws of large numbers take over, and exponential growth starts to flatten out.  On the flip side, Apple may have as good or better chance to rise 10% over the next 6-12 months as a random small cap stock. I think the list could have added:  - Save in regular intervals using the same strategy.  Just to make sure that good old dollar cost averaging is thrown in. That's probably where most people go way wrong. Save money all year, dump it on a stock they like because some family friend investment expert said that 'apple prices will go up' with out explaining that you need to take advantage of mean reversion to help spread the risk. Re-invest it in the business, invest it long-term somewhere. It is a very bad business practice to have too much cash lying around. That cash could either generate a higher profit % used in the business or it could generate more money long term being invested somewhere. It seems apple has now done the latter, up until now it's been largely invested in cash-like things. If you look at S&P 500's closing price for the first trading day on December and January for the last 20 years, you will see that for 10 of these years, stocks did better overall and for 10 others they did worse. Thus you can see that the price of stocks do no necessarily increase. You can play around with the data here "Because more people bought it than sold it. That's really all one can say. You look for news stories related to the event, but you don't really know that's what drove people to buy or sell. We're still trying to figure out the cause of the recent flash crash, for example. For the most part, I feel journalism trying to describe why the markets moved is destined to fail.  It's very complicated. Stocks can fall on above average earnings reports, and rise on dismal annual reports. I've heard a suggestion before that people ""buy on the rumor, sell on the news"". Which is just this side of insider trading." "There's an expression, ""stock prices have no memory."" Apple trades at about $115. Why would I carry my shares at anything but $115 even though I paid say $75 a share, while you just bought it at $115?  The only difference, perhaps, is that if I hold them in a non retirement account, I might track the net I'd have, post tax."
