May I ask which expiration date / strike you see a .99 delta for 7.76? There are a few things one wants to keep in mind here:
1) We are dealing with very low Implied Volatility right now (multi-year low), which means option prices are very low when buying. So this is not something you can repeat throughout the year. If you can, pull up some historic option prices to see what the leverage would be.
2) If it's a near term option it's possible that it does not move enough to make back the cost of the premium. (Time decay will cause the option value to drop faster than the underlying goes up).
3) Is the option actually being traded at that price? I've often pulled up quotes for options that have great prices only to find the liquidity is non-existent and could not be bought at that price.
Oh, and of course the more fun calculation (which is what the institutions are doing on their side) what is the actual risk premium rate of return on this trade versus a risk free (or low risk) trade. For example:
Underlying @ 216.15
CALL PRICE @ 7.76
STRIKE @ 208.50
Expiration: 31-01-2017 (Chosen to make it 6 months out)
If SPY @ 216.15 (flat) after 6 months
Exercise Option: Buy @ 208.50, Sell @ 216.15. Total Profit = 7.65 - 7.76 = -0.01
If SPY = 200 (drop) after 6 months
Option expires worthless (no reason to exercise and buy @ 208.50 when market price is 200)
If SPY = 220 (raise) after 6 months
Exercise Option: Buy @ 208.50, Sell @ 220. Total Profit = 11.50 - 7.76 = 3.74
But now we compare it to a 'Risk Free Rate Of Return'. If we take that at 1.7% on the 10-year bond:
Investment = 7.76
1.7% of 7.76 = 0.13192
Over 6 month period = 0.06596
Therefore the investment of 7.76 must return at least 0.06596 to be better than the risk free rate of return.
This means SPY must increase in value from 216.15 to 216.2159 (0.015% increase)
If general consensus is that S&P 500 will *NOT* raise by at least 0.015% this year (the consensus is it should drop a little form this 'high' point), then this would be deemed
a trade unlikely to be profitable.
This could explain why you see the option price low enough to get higher leverage. In other words: People are selling you cheap options because no one expects SPY to go high enough
for a profit to be realized.
Also, this is using the 10-year as a risk-free rate. You could also use different investments at a higher risk but higher return to measure the rate of return on this strategy. For example,
if you invested in high yield bonds or preferred or REITs, you could look at a return of 10% instead. In which case:
Investment = 7.76
10% of 7.76 = 0.776
Over 6 month period = 0.388
Therefore the investment of 7.76 must return at least 0.388. Which means SPY must increase from 216.15 to 216.538 (a 0.089% increase)
If you think the S&P 500 will increase by at least 0.089%, then this could be a profitable trade. Of course, if it drops it's not profitable
Also it is worth remembering: A delta 1 option does not stay delta 1 forever. As the expiration date approaches or the underlying moves the delta will change.
So some of the key risks are:
1) If there is a sudden drop (we hit 180), the option becomes worthless really quickly.
2) If we stay flat or low, the option value will decrease over time.
Delta 1 is great for leverage. But if it still doesn't budge, it doesn't matter how much leverage you got
