For example as I write this, the S&P500 is down 0.58% from yesterday. This confuses me because there are 500 different companies in a massive range of different fields and I can't see why one thing could be related to all of them at once to bring them all down. Could it be like a number big funds withdraw together at a particular time or something?

I recently found a website where you can buy technology from America and have it delivered to the UK. My only concern is will this technology work ok over here in the UK? I remember a few years ago my dad sent an iphone to a relative in Sudan and the iphone didn't work there or at least something about it wasn't working. Could this be an issue with the US to UK too?

Is it that say a stock falls 5% one day then gains 5% the next day, could an explanation for that be that people will notice this is a good dip opportunity to buy and the price rises the next day accordingly? Or is every days change in stock price directly related to news about that stock?

I would like to know how important it is to go to a good medical school and what effect it has on your career. For example could you specifically compare studying at Cambridge / University College London / Imperial College London /Kings College London?

Lets say you have an offer to study at both Cambridge and Kings College London. Of course Cambridge is more reputable but it could be argued that the social life at Kings College London as well as the course is more appealing. Would it be worth sacrificing the difference in reputation or is this going to make a big difference later in your career?

I will give examples of forums and my problem with each:

Yahoo answers: used to be perfect until they removed commenting on peoples replies to your post.

Reddit: subreddits have too many rules and remove your question too much of the time

Stack Exchange: users are given too much power to remove/delete your question

Quora: no option do add explanation after your question title

Now you can see my problem with each of these, does anyone know of a forum with none of these problems and also has enough active members?

" Many testing techniques interacting with web servers such as XSS rely on ensuring authentication obtained on a target be kept active. A mechanism for registering and maintaining open authentications identified during a test for the duration of the console session may provide an additional utility to enable more modules to target techniques that need valid authentication to be maintained. One such authentication token would be data retained in a cookie for a web service. This project would lay the groundwork for registering gathered or generated authentication tokens against a target to be refreshed and sustained until a console exits, or in some cases across console restarts. "

Please can someone put it into like 2 sentences of English that could be understood by someone with no computing experience, for example a giraffe

Having looked at a couple graphs of companies when they pay their dividends, I notice that the stock price rises and falls but not particularly quickly. I would have thought that maybe it is very difficult to buy and sell quickly enough but in fact the rise and fall of the stock price happens over a number of days giving an investor what looks like plenty of time to pull out.

But despite this I doubt it can be that easy? Like you can't be telling me that I can simply buy shares of a company 5 days before the dividend payment, receive say 3% dividend + 3% increase in share price then pull out? What's the catch?

Side Question: When do most companies pay their dividends? Do each of them have their own random dates or is there some specific dates that most companies pay on?

Why is it that for example Sheffield seems to have few international students but LSE has about 70% international students?

I live in the UK and I know when prisoners are released in the UK, although it is very difficult for them to find a job with their criminal record, I imagine they still manage to find a place to live due to the benefits system in the UK. 

However I just clocked that in the US there's no such thing as benefits. So do all released prisoners end up homeless or what?

When I set up windows I created a 4 digit passcode. Then I set up Microsoft Teams with my university login and without thinking I checked the box to "allow my organization to make changes on my device". Then another time when I came to sign in I found my computer saying that my organization requires me to have a 6 digit passcode. Now I have a 6 digit passcode but I want be able to sign in without any authentication. 

I tried unchecking "users must enter username and password" in netplwiz but that didn't work either

I've been trying to find the owner of a domain name I want but I can't find their information anywhere. They don't have their information on whois, apart from the fact that they are somewhere in Lebanon. The only option I can seem to find is using domain name brokers but I am confused as to how the domain name broker is going to be able to find the domain name owner? Like do they have some secret alien agents or something or how exactly do they find the owner?

I have been thinking about day trading but I just want to know what the limitations of it are as I'm new to investing. Like what stops people from making say 0.2% gain per day? As it is very likely that A stock will fluctuate such small amounts.

I find that when using Google Chrome to open a pdf, if I Ctrl-F for a string, it only highlights one instance at a time and you need to press the arrow key to go to the next word. I find this quite annoying as I often want to see all the instances highlighted. Is there a way to change this so that all instances are highlighted?

my bluetooth headphones cannot connect to multiple sources. While im in a discord call, I can only hear the discord call but not a youtube video at the same time. My wired headphones used to allow for this. Is this normal? How can I change it?

I've noticed that I think maybe just in the past month or so, the stock price of AMD, NVIDIA, TSMC and intel are all falling. Is there a particular reason for this? 

It would need to be a proper deck too, not one of those fake ones for kids. Preferably not used as well. I've found some just under £25 but idk if I can get down to £20
