Here is a link to an older study that makes the case for MaxPain
option price "pinning" on Options Expiration day relating only to a
group of "suspect manipulated stocks". What I think is a telling,
is when the S&P 500 stock index options "pin" on OE day......
what does that suggest to you?.......
Ok, then non-pinned are stocks those exempt from manipulation (I
initially assumed the opposite). Take two mining stocks then, IAG
and GDX. The former was pinned on Friday to 15, yet its January max
pain comes at 17.5. There is no difference for GDX, both show 46 or
47 as the max pain prices.
Two inferences from this are:
1. Widely traded stocks are more prone to manipulation (the
intuition suggested me the opposite, yet GOOG, SPY are fine
examples). IYR and CSIQ then are not.
2. IAG could close at 17.5 on January's OE day, that's a 12%
gain from its close on Friday. Easy money, huh?
