That all depends, an overseas corporation is $500-$1000 which acts as intermediary, there are beneficial ownership issues but that comes down to broker, you will find one, there are some ideas on reddit how to also do it, or emigrate which is always the more interesting option!
What does that spread have to do with Nasdaq? And what is your definition of synthetic? I've only heard that term in use for options, not futures.
Here's a picture (NQ chart in white with index points on left axis) The cash value of the spread is on the right axis (differential of contract notional amounts). They trade in sync because NDX is free-float cap weighted and DJX is price weighted. The spread gives exposure to BETA risk, i.e. it's a beta ratio spread as well as being a synthetic index -- tradable by taking long/short exposure in related index futures. You can replicate this exposure using options, but you will have to buy the synthetic (long/short ATM call/put in MES or SPY) & (short/long the ATM call/put in MYM or DIA) You may want to consider it since the risks are far lower than even outright index micro's, e.g. MNQ.
cfds arent allowed for americans do you know of any cfd brokers that allow american citizens and residents to sign up?
Oh yeah? And what were those options trading for at the time where brokerages literally told customers they could only sell and not buy? What was the premium you would have had to pay to do that above and beyond what it would have cost to just simply buy a stock? ( Except that you weren't allowed to buy due to apparent collusion between Melvin , citadel, dtcc and rh + others) In addition you have the issue of counterparties at a time when Thomas Petterffy said "We have come dangerously close to the collapse of the entire system,”
I'm not sure what your problem is, but look at the IV on 1-27-2021. https://www.alphaquery.com/stock/GME/volatility-option-statistics/10-day/iv-mean Even "plebes" understand that means you're not going to be able to buy cheap options. Then there's also the issue that certain options trading was also shut down. https://www.fool.com/the-ascent/buying-stocks/articles/why-are-brokers-halting-gamestop-trading/ Setting that aside: During a short squeeze, those getting squeezed are going to be desperate for actual shares of the stock on the day they have to deliver it. Some option that settles after they were supposed to deliver shares is not the same thing. In a short squeeze, you're not dealing with the fundamental valuation of the company any more. The existing betting around the stock has been so severe that covering those bets is expected to drive the price. The stock might only be worth $10 on a normal day, but on that particular day, they might have to pay $100 because to they need to convince enough people to sell shares to cover all the bets.
With that in mind, can you please change your avatar pic? Every time I see posts of yours I see that pic, and it makes me think you are licking a lollipop. (I know what it really is, a selfie with face blurred.) But gah! My OCD gets to me every time on this. How about a pic of a lion gutting a gazelle or something?
