Is it possible to sell a stock at a higher value than the market price?
You can ask for 305rs, but as long as shares are available at lower prices you won't sell. Only when your ask becomes the lowest available price will someone buy from you. See many past questions about how buyers and sellers are matched by the market. The core issue is to understand what 'selling a share' means. There is no special person or company that takes the share from you; you are selling on the open market. So your question is effectively 'can I find a guy on the street that buys a 10$-bill for 11$ ?'  - Well, maybe someone is dumb enough, but chances are slim. Yes  You could write a covered call and the stock gets called away at the price + premium.  You could convince someone to buy it regardless of the market price.
Par value of common stock is essentially a historical artifact; it is a price at which the company will redeem shares directly.  If common stock has any par value at all, it is always so low that no one would ever redeem, preferring to sell in the market at a better price.  Par is obviously much more relevant to debt securities than equities. So you do need a strike price.  ljwobker's letter is a typical one, in that companies often make the strike price for granted options a formula based on the market price of the stock at the time of the grant, say 100% of market or 110% of market.  But you will obviously need to find out what strike your company is offering. "Just read the book Flash Boys by Michael Lewis.  It describes this process in detail, albeit a bit more dramatically than it has to.  Basically what ""HFTs"" (high frequency traders) do is they set up their line to the exchange so its microseconds faster than everyone else.  Then they test out the market with tiny orders, seeing how fast it's getting filled - if these are getting filled immediately, it probably means there's a big order coming in from an investor.  So the algorithm - and it's all algo-based obviously because no human can remotely hope to catch this - will detect that as soon as there's a spike in volume, it will buy all of the volume at the current price, and sell it back for higher, forcing the big investor to take on higher prices.    Another case is that some HFTs can basically buy the entire trade book from an exchange like Nasdaq.  So every time someone places a market order for 200 shares of a 6.5 stock, the HFT will see it, buy up all the current stock from say 6.5-6.6 and sell it back at 6.7.  Not rocket science if you already get info about the trade coming in, in fact this is basically market making but performed by an ""evil HFT"" instead of a ""trustworthy bank.""    But honestly there are a lot more ways to make money from HFT than front-running, which isn't even possible anymore because exchanges no longer sell their books to HFTs." There is no direct relationship between volume and stock price. High volume indicates how much stock is changing hands. That can be because people are enthusiastically buying OR enthusiastically selling... and their reasons for doing so may not agree with your own sense of the future value of the stock. Higher volume may mean that the price is more likely to change during the day, but it can be in either direction -- or in no direction at all if there isn't a general agreement on how to react to some piece of news. It's a possibly interesting datum, but it means nothing in isolation. "You may look into covered calls.  In short, selling the option instead of buying it ... playing the house.   One can do this on the ""buying side"" too, e.g. let's say you like company XYZ.  If you sell the put, and it goes up, you make money.  If XYZ goes down by expiration, you still made the money on the put, and now own the stock - the one you like, at a lower price.  Now, you can immediately sell calls on XYZ.  If it doesn't go up, you make money.  If it does goes up, you get called out, and you make even more money (probably selling the call a little above current price, or where it was ""put"" to you at). The greatest risk is very large declines, and so one needs to do some research on the company to see if they are decent -- e.g. have good earnings, not over-valued P/E, etc.  For larger declines, one has to sell the call further out.  Note there are now stocks that have weekly options as well as monthly options.  You just have to calculate the rate of return you will get, realizing that underneath the first put, you need enough money available should the stock be ""put"" to you.   An additional, associated strategy, is starting by selling the put at a higher than current market limit price.  Then, over a couple days, generally lowering the limit, if it isn't reached in the stock's fluctuation.  I.e. if the stock drops in the next few days, you might sell the put on a dip.   Same deal if the stock finally is ""put"" to you.  Then you can start by selling the call at a higher limit price, gradually bringing it down if you aren't successful -- i.e. the stock doesn't reach it on an upswing. My friend is highly successful with this strategy. Good luck" It is unlikely that buying 100 shares will have any effect on a stock's price, unless the stock's average trading volume is incredibly low.  That being said, no matter how many share you buy, there's no way to know what the impact on the price will be, because that's only one factor in how shares are priced.  If anyone could figure out the answer to your question then they'd be extremely rich, because they'd simply watch for big share trades and then buy those stocks on the way up. The market makers who actually execute the trades are the ones who set the prices, and most stocks have multiple market makers trading the stock, so the bid/ask you see is the highest bid and lowest ask.  The market makers set the price based on what the trend of the stock is.  If, for instance, there's a large number of sell orders against a stock, the market makers will start dropping the bid prices as they fill execution orders, and as they see buy orders increase, they'll raise ask prices as they fill execution orders.  The market makers earn the difference between what they paid to buy someone's stock who was selling and what they get from someone else who buys it. This is a simplified explanation, so pro traders, don't beat me up! (grin) So, basically, it takes quite a bit of share volume in one direction or another to affect a stock's price.  I can guarantee a 100-share trade wouldn't even be noticed by market makers. I hope this helps. Good luck! Fiduciary They are obligated by the rules of the exchanges they are listed with. Furthermore, there is a strong chance that people running the company also have stock, so it personally benefits them to create higher prices. Finally, maybe they don't care about the prices directly, but by being a good company with a good product or service, they are desirable and that is expressed as a higher stock price.  Not every action is because it will raise the stock price, but because it is good for business which happens to make the stock more valuable. How would this trade behave IRL? I don't know how the simulation handles limit orders and bid/ask spreads to know it's feasible, but buying at 4.04 when the current ask is 8.00 seems unlikely.  That would mean that all other sell orders between 8.00 and 4.04 were fulfilled, which means that there were very few sellers or that sell pressure spiked, both of which seem unlikely. In reality, it seems more likely that your order would have sat there until the ask dropped to $4.04 (if it ever did), and then you'd have to wait until the bid rose to $7.89 in order to sell them at that price. However, that kind of swing in option prices in not unrealistic.  Options near at-the-money tend to move in price at about 50% of the change in the underlying, so if amazon suddenly dropped by $5, the option price could drop by $2.60 (from 6.66 to $4.04), and then rise back to $7.89 if the price rose $8 (which would be 1% swing and not unheard of intra-day). But it sounds like you got very lucky (or the simulation doesn't handle option trading realistically) - I've traded options in the past and have had some breaks similar to yours.  I've also had bad breaks where I lost my entire investment (the options expire out-of-the money). So it should be a very limited part of your portfolio, and probably only used for risk management (e.g. buying put options to lock in some gains but keeping some upside potential). When a stock is going to become public there's a level of analysis required to figure out the range of IPO price that makes sense. For a company that's somewhat mature, and has a sector to compare it to, you can come up with a range that would be pretty close. For the recent linkedin, it's tougher to price a somewhat unique company, running at a loss, in a market rich with cash looking for the next great deal. If one gives this any thought, an opening price that's so far above the IPO price represents a failure of the underwriters to price it correctly. It means the original owners just sold theirvshares for far less than the market thought they were worth on day one. The day of IPO the stock opens similar to how any stock would open at 9:30, there are bids and asks and a price at which supply (the ask) and demand (bid) balance. For this IPO, it would appear that there were enough buyers to push the price to twice the anticipated open and it's maintained that level since.  It's possible to have a different system in which a Dutch auction is used to make the shares public, in theory this can work, it's just not used commonly.
