So I'd like to look at your two positions (a credit put spread) and your sale of March14 puts independently first. Both plays are bullish, your first play (credit spread) bets that the stock will be above 123.4 on august 17th and it will be profitable from 123.4 upward (17.85-6.25=11.6, 135-11.6=123.4.
My thoughts: today's price is roughly 122 so essentially you are buying stock at today's price. In return for buying stock at today's price, you are given upside to 135 after earnings. This only gives you 11.4 dollars in profit. For that limited upside, you are compensated with a limited downside, you can only lose 8.4.
Now, it depends on what you think will happen at the earnings call. If you have this strategy, you are protecting yourself from a major loss but predicting that at best there will be minor gains (under 10%) in the stock price. One thing that i don't like about it is that if there is a slight miss, and the stock moves by only 5 dollars down, you are on the hook for losing money. However, if there is a major gain you can only participate in the first 11.4 dollars of it.
Half of the options game is deciding what event is likely to happen and what is not likely to happen, and the other half is to correctly choose the strategy. I think if you're new, this one will not bankrupt you either way and might be a kinda safe strategy to participate in the option market at the same time as limiting your downside.
If you add in your march put sale, you now add in tremendous downside to a tesla slide. If they report and drop, you are limited in the previous credit spread, but then for the part that you're safe from (115 and below) you then become exposed at 105 again. Plus there will be increased IV and it will be more costly to clean out of the position on a slide to 110 after earnings.
I guess that i don't suggest both of these in combination. You seem slightly bullish, and you might as well combine your protective put at 115 with your 105 put sale, in conclusion not selling a protective put. Then you're profitable all the way down to 117.15. There's very little extrinsic value in this play, and its profitability depends on the stock moving up. if you are more neutral, sell the 130 and claim more of the extrinsic value. If you are more bullish, sell the 140 and give yourself a little more upside.
