How does the futures market affect the stock market?
Can someone please explain how traders and investors use this price difference to trade? People use the price difference for small arbitrage between the futures and spot markets, where the larger spreads are reflected in the options markets. The spread in the options market dictates the VIX which many investors also use in their decision making process.  And most importantly how the futures market affects subsequent moves in the stock market? The futures market effects the stock market where large contract holders move the entire futures price. This causes reactionary moves amongst all of the aforementioned arbitragers, who are hedged between the futures and spot markets. With the /ES this is reflected down to actual individual stocks based on their weightings in the S&P 500 index. Many of those stocks have smaller companies that are also linked to them, such as a widget manufacturer for a gigantic ACME corporation listed in the S&P 500.
1) Explicitly, how a company's share price in the secondary market affects the company's operations. (Simply: How does it matter to a company that its share price drops?) I have a vague idea of the answer, but I'd like to see someone cover it in detail.  2) Negative yield curves, or bonds/bills with negative yields  Thanks! "The issue with your point is that government has/does move to make decisions in the markets to institute their political views or agendas. Of which these views and agenda do not often take into consideration any of the unforeseen consequences in the light of market realities. The market realities which I speak of are everything affected by government action from businesses dealing with the cost of extra added government regulation on their bottom line, employee costs, taxes, the impact of subsidies, and price controls, etc in a competitive market where everyone is looking for an edge over their competitors. However with government many times these market realities are often ignored when making broad and over-reaching governmental polices based on political agendas and the whims of the public rather then on solid and sound economic decisions.  Which in turn these governmental polices effect many, many more people then businesses acting for their own needs to ensure their survival in the marketplace. Thus having a president who does not or willfully will not acknowledge how government interaction in the market place can create unintended and often negative results is worse in respects to having a president who does understand how the ""bottom line"" is effected via government action and attempts to reconcile both in light of making a decisions that effects the economy as a whole." "Futures are an agreement to buy or sell something in the future.  The futures ""price"" is the price at which you agree to make the trade.  This price does not indicate what will happen in the future so much as it indicates the cost of buying the item today and holding it until the future date.  Hence, for very liquid products such as stock index futures, the futures price is a very simple function of today's stock index value and current short-term interest rates.  If the stock exchange is closed but the futures exchange is open, then using the futures price and interest rates one can back out an implied ""fair value"" for the index, which is in essence the market's estimate of what the stock index value would be right now if the stock market were open.  Of course, as soon as the stock exchange opens, the futures price trades to within a narrow band of the actual index value, where the size of the band depends on transaction costs (bid-ask spread, commissions, etc.)." The Nikkei 225 is a price-weight index composed of 225 of the leading companies that trade on the Tokyo Stock Exchange.Most good binary options platforms provide their customers with the opportunity to trade options that are linked to the Nikkei 225. Traders who are interested in trading such options should carefully consider the nature of the Japanese stock market by studying how it is affected by – and has an effect on – the US economy and the US markets. Very important. Returning again to the example of the farmer, efficient, liquid markets that fairly reflect the price of a given asset allow that farmer to run his business as cost effectively as he can. That (in theory) lowers the price of his goods for the consumer. If he wasn't able to efficiently hedge, he would have to charge a premium to reflect the price risk he takes on between planting and harvesting his corn.  Being pedantic here but single stock futures markets are extremely quiet. If you were the owner of a company and you traded *options* on your company stock (a hilariously common form of insider trading) yes, that would be illegal and the SEC would certainly come after you. Stock values are generally reflective of a company's overall potential; and to some extent investor confidence in the prospect of a continued growth of that potential. Sales over such a short period of time such as a single weekend do not noticeably impact a stock's valuation.  A stock's value has more to do with whether or not they meet market expectations for sales over a certain period of time (generally 1 quarter of a year) than it does that they actually had sales (or profits) on any given day. Of course, catastrophic events, major announcements, or new product releases do sometimes cause significant changes in a stock's value.  For this reason you will often see stocks have significant volatility in periods around earnings announcements, merger rumors, or when anything unexpected happens in the world that might benefit or hurt their potential sales and growth. But overall a normal, average weekend of sales is already built into the price of a stock during normal trading. Irrational exuberance leads to crashes but the fundamentals recover.  This is absolutely going to hurt some companies with already announced IPO's and will delay others from going public.  But nothing fundamental has changed - some speculators just got shot down. In principle, the stock price should see no change in the days leading up to an earnings announcement, and then at the moment of the announcement, the stock price should move in the direction of the earnings surprise (relative to the market's belief of what earnings were going to be). In practice, stock prices tend to drift a little in the direction of the surprise shortly before the announcement and the associated price jump. This could be because smart investors were able to replicate the computations to predict the announcement or because information gets illegally leaked ahead of the announcement.  So I guess your bullet point B is a likely scenario. Note that hedging activity in the options market will not affect stock price one way or another.  Options transfer risk from one party to another but net to zero.  Intense hedging activity may be able to push up the price of options (increasing the implied volatility), but it shouldn't affect the price of a stock one way or the other. For this reason, bullet point A is not the case. Note that price behavior after the announcement is also interesting: it seems to take some time to reach the correct price instead of jumping directly to it as economists would predict.   This phenomenon is known as post earnings announcement drift.
