But frequently especially when there is so much money at stake. Within 1% would be a confirmation.
closed in the max pain range i see
Just wanted to point out this additional thing: I think the explanation in Investopedia is incomplete, and misleading to a certain extent as it appears to be assigning a certain level of 'intent' to option writers driving the price towards certain 'max pain' price levels.
But if we look at how modern market makers operate, then the price moving towards 'maximum pain' is a side effect of delta-neutral inventory management.
This is especially true for Tesla, where there's a 'bathtub curve' distribution of options risk-at-value:
Since the $TSLA stock is very polarized, with price expectations wide apart and a lot of high-leverage options bets, most of the options are written by market makers, few are directly traded between longs and shorts.
This means that MM delta-hedging builds up an inventory of shares either short or long, representing the downside/upside risk presented by the options market. As expiry draws closer, the probability of tail events decreases exponentially, and the risk drains out of the options - while open interest does not change nearly as fast. This means that options writers with a delta hedge will have excess inventory and need to drain this inventory: net writers of PUTs are going to buy shares as time passes (they were short hedged up to now), net writers of CALLs are going to sell stock. The equilibrium price of these two forces is usually close to the 'maximum pain' point that derives from the open interest.
The strength of these two forces depends on the total open interest in options, which was ridiculously high yesterday: 353K PUTs, 171K CALLs, a total of over 50 million TSLA shares of exposure on that single expiry day, with a total value at risk of over 15 billion dollars...
It is also I think a partial explanation for the recent peak FUD: if shorts had any negative story about Tesla, or had media contacts to manufacture/magnify a negative story about Tesla, then this week was probably the most profitable moment to use that resource.
Barring cataclysmic events it seemed very likely to me that the stock would trade close to the maximum pain point.
BTW., according to maximum-pain yesterday's ideal closing price should have been $305, while it closed at $299: this might be explained by the limitations of the max-pain metric that looks at the whole open interest. If we look at the near-the-money distribution alone:
Code:
PUT $277: 841, CALL $277: 1,227
PUT $280: 6,998, CALL $280: 2,754
PUT $282: 1,113, CALL $282: 431
PUT $285: 4,104, CALL $285: 2,691
PUT $287: 3,381, CALL $287: 694
PUT $290: 6,962, CALL $290: 4,123
PUT $292: 1,337, CALL $292: 1,070
PUT $295: 2,937, CALL $295: 3,366
PUT $297: 1,401, CALL $297: 2,423
PUT $300: 10,391, CALL $300: 8,876
PUT $302: 404, CALL $302: 1,852
PUT $305: 1,567, CALL $305: 4,608
PUT $307: 256, CALL $307: 2,086
PUT $310: 2,854, CALL $310: 6,599
PUT $312: 151, CALL $312: 1,509
PUT $315: 2,930, CALL $315: 3,796
PUT $317: 159, CALL $317: 1,639
PUT $320: 5,827, CALL $320: 6,583
PUT $322: 103, CALL $322: 1,028
And assume that the residual risk of billions of dollars of other open interest is at most a hundred thousand shares equivalent or so, then the distribution of inventory related to the above open interest clearly puts the equilibrium price to between $297 and $300.
Since there wasn't particularly strong buy or sell pressure yesterday otherwise, I'd guess that the end of day draining of residual inventory defined the price action: which was particularly visible in the final few minutes when market makers got rid of
all the residual delta-hedge TSLA inventory.
Next week's $TSLA price action should be a lot less constrained by options expiry, the next bigger options day is October 19th:
Code:
2018/Sep/21: PUTs: 353,566 ; CALLs: 171,979
2018/Sep/28: PUTs: 29,545 ; CALLs: 43,110
2018/Oct/05: PUTs: 15,514 ; CALLs: 19,121
2018/Oct/12: PUTs: 7,210 ; CALLs: 15,223
2018/Oct/19: PUTs: 188,546 ; CALLs: 72,724
2018/Oct/26: PUTs: 3,586 ; CALLs: 2,284
2018/Nov/02: PUTs: 1,879 ; CALLs: 1,157
2018/Nov/16: PUTs: 65,619 ; CALLs: 35,972
2018/Dec/21: PUTs: 75,741 ; CALLs: 46,707
2019/Jan/18: PUTs: 458,235 ; CALLs: 209,081
2019/Feb/15: PUTs: 6,889 ; CALLs: 9,536
2019/Mar/15: PUTs: 53,099 ; CALLs: 34,513
2019/Jun/21: PUTs: 59,075 ; CALLs: 34,407
2019/Aug/16: PUTs: 18,125 ; CALLs: 12,503
2020/Jan/17: PUTs: 190,491 ; CALLs: 70,491
2020/Jun/19: PUTs: 2,137 ; CALLs: 1,346
total: PUTs: 1,529,764 ; CALLs: 781,144
But even Oct 19 is only going to be half the magnitude of yesterday's options expiry event.
The next really big one is going to be the 2019 Jan 18, with 665K options already open (!). Short squeezes and big drops are more likely between these options events, which act as 'synchronization points' for the pricing between options and the underlying stock.
Of course if the fundamentals change then this many outstanding options will greatly enhance volatility, both up and down, as market markers scramble to delta hedge tens of billions of dollars of open options interest: the current open interest (excluding the 500K options that expired yesterday) is over 170 million TSLA shares (!), with a maximum total value-at-risk of over 50 billion dollars...
At least that's my reading of the numbers - is there anything important I missed perhaps?
