I'm not too familiar with futures. I think it's where people bet on where a stock (or other instrument) will go (either up or down).
Futures in entering into a contract to buy [or sell] an item [stock/commodity/index/etc] at a specified rate at a specified date in future. Generally exchange govern when the futures close. These are generally set for a specified date; i.e. Every Thursday / last Thursday of month etc.
I'm wondering, is there a way for me to see for example for a certain stock, let's say AAPL for example.
AAPL may be incorrect example. As much as I understand in US futures is allowed only on commodities and energy companies.
Can I tell from these futures how many people thinks it's going to go up vs down? for example, let's say 100 people think it'll go up, while 20 think it'll go down. Then couldn't I use this information to assess that aapl may go up. (since 80% of people think so).
Generally the futures and current price more in tandem. If the future goes up, it gives an arbitrage and hence the current price corrects immediately and the arbitrage vanishes. Hence there is very less opportunity.
If so, where do I find this information?
Most futures are traded on the Chicago Mercantile Exchange.
