I guess the classic ZEBRA is to go long 2 Calls at 75 delta, and short the one ATM, ostensibly 50 delta. So 75 + 75 - 50 leaves 100 deltas.
Though I often see it as "buy 2 70's and sell 1 50." But I don't understand that because it adds up to only 90 deltas for the position.
But I think the important thing is to
cancel out the extrinsic values, so buy the Calls that have extrinsic value equal to about
half of the ATM Call. For
TSM 6 weeks out (the Aug monthly):

You probably know how to calculate the Extrinsic value in the 170 Calls, but find the Midpoint (19.48), add it to the Strike of 170 to get 189.48, then subtract the stock price of 183.99 to leave 5.49 Extrinsic in
each 170C.
Since we're buying 2, double that to 10.98.
Then sell the ATM 185C for Midpoint of 10.72.
And look,
the Extrinsic values almost cancel out: buying 10.98 and selling 10.72
And the Deltas are 75 + 75 - 54 = 96, pretty close to 100.
Then plot it in OptionStrat or similar, and this is what they look like:

If you've done it right you'll always get that shape:
Breakeven right at spot.
1:1 on the upside.
2:1 on the downside.
But Max Loss capped at what you paid for it.
It cost you 28.23, so you're getting 6.5x leverage to the stock, but participating 1-for-1 with upside moves. (And yes, 2-for-1 on downside moves.)
And the cost here is 15% of spot, so if you do nothing at all to manage losses, it's like having a 15% stop-loss on shares.
And no time decay! (Or very little.)
Then go sell a weekly Call against it, say the 12Jul190C at 31-delta for 1.90, and that's an RoR of 1.9/28.23 = 6.7%.
In the last week (or the week before), sell the spread for its (hopefully) appreciated value and put another one on. You can go longer or shorter, paying more or less accordingly, and getting less or more leverage. I'm liking 30-45 days.
Play around with them, I think you'll like them.
But remember that they're a stock-replacement strategy, not a speculative long Call like you might favor, so the use-case is different. I buy them specifically to sell CCs against, and I buy into strength.
