However, Dan Perper, a Partner at Peak 6, one of the largest option market makers and proprietary trading firms, has confirmed that the trades are part of a "box-spread trade."
"This was done as a package in which the box spread was used [as a] means of alternative financing at more attractive interest rates" explained Perper.
Simply put, two parties agree to trade the box at a price that essentially splits the difference between current rates.
For example, the rough numbers would be that given the September 700/1700 box must settle at a value of 1,000 -- it is currently trading around 997 -- that translates into a 5% interest rate.
For the seller it is a way to borrow money at a slight discount to the prevailing rate, and for the buyer, it is a way to lend money at a low rate of return, but it's better than nothing at a time when others are scared and have painted themselves into a box (ha ha) because they have run out available funds.
Okay, I've done enough research to easy my mind. Two sources [that I trust] indicate that there is "not much to worry about". But some are suggesting that this move is in anticipation of something happenning in Iran. No one that I've seen, other than various conspiracy sites, are talking about another 9/11 attack on US soil.
