I use StockTwits to follow S&P500 and major cryptocurrencies but recently found "SPX6900" Is this a joke? Why is it on StockTwits? There are only 500 companies in the S&P index, not 6900.
Why would StockTwits, a highly reputable trading/finance forum put a fake S&P6900 on the platform? I'm assuming this is some kind of cryptocurrency as the commentors are all seemingly young people talking about "flipping the S&P500"
Does anyone have more info on this? Is it potentially a scam?
