Hi Bob -

You are correct in your info.  Let's looks at it a different way......

Bear in mind that you picked an arbitrary 1000 shares of stock to equal
$125.

However, if you look at the total value you are "buying",  about  $14,000 
controls you $275,000 of S&P 500 "stock" .
For the same comparison, you would need 18,333 shares of the $15
stock....thus, your 1/8 point spread would now cost you   18,333 shares   X
.125 = $2,291 !


IE, The SPREAD cost to leverage $275,000  of stock costs $100 in futures,
while costing $2,291 in this $15 stock....and this is REAL money out of
your pocket, on each trade, taken in by the market maker or floor trader.


Put another way:

In order to profit from an identical market move the $15 stock will cost
you $2,291 spread vs: only  $100 to  *BOTH*  enter and exit the market. 


Actually, if we use 50% margin on the stock spread expenses get reduced by
1/2, though there is then margin interest to contend with.

Where ARE the customer's yachts, anyway?
