I don't understand "shorting" nor the "infield fly rule"
What happened is that they sold (created) options. They sold 'call' options which means they created an obligation to sell shares of an ETF at a given price. This ETF goes up when natural gas price goes down. In fact, it goes uo three times as fast as the natural gas price goes down. If natural gas drops by 1% in a day, this ETF should go up by 3%. When the price of natural gas dropped significantly, the price of the ETF went up A LOT and the firm had committed to selling the shares at a much lower price than wht they had to buy them for. A 'buy high, sell low' strategy. Never sell 'calls' unless you own the stock/ETF.
As for the infield fly rule, I would think a frog would know all about flies.
