It means he paid 1.25 for call options which give him the right to buy SPY at 215 a share, regardless of how high the stock goes.
Unfortunately his call options last print today was 9 pennies.
With options you can lose your entire investment quickly in a short period of time. Once the options expire there is zero chance of a redo or waiting it out. You take a 100 percent loss on your investment.
That said it is a limited risk play, but if you overdo it you can lose your entire trading capital.
So let's say he bought 10 contracts. At 1.25 it would mean he would have paid 1250 dollars to open a position.
If spy went to 220 for example his position could be worth 5000-5500 dollars
But if it goes under like today it is only worth 90 dollars.
If spy does not break 215 by sept 18 he would be out the entire 1250 dollars.
