Jeffrey,
Our structuring desk did further analysis on the transaction — please see below. As discussed, let's speak further
tomorrow morning.
Below numbers are still as of E0D yesterday:
Here is the same table as earlier and additional explanation regarding what it means.
Strike 1 I Implied- I Current
Garman Valuate I Date I Realizedvol I Realized I Implied
CLHS 60% 13-tar-15 79% -19% 84%
cus 43% 13-Jan-15 77% -33% 56%
CI.K5 42% 14-Jan-15 73% -31% 54%
Let's focus on CLJS (Apri115) and similar applies to the other nodes. Vol strike was 43% and
realized vol has been 77%. If the index had exposure only to this contract and not at all to
the other contracts, and if realized vol up to expiry of this contract were also 77% then the
implied-realized diff is 43%-77% = -34%. That is massive. This does not mean that you would
lose 34% of the notional, but at least illustrates that you should expect the loss to be big.
How much you actually lose is a daily path dependent calculation and cannot be summarized in
a few sentences. If realized vol was EXACTLY same as implied vol also, the gain/loss would
not be zero, but is a path dependent function.
Back of the envelope, with a 34% implied-realized difference, one can expect a loss of 17%
because the index has a vega of, on average 0.5% of index notional; but at any given point in
time even with vols unchanged, the vega could be anywhere between 0.33% and 0.67% (this is in
steady state with vols unchanged, with changing vols, it could be a wider range).
As we know, the strategy of the index is to sell 3 straddles (collecting premium); and delta
hedges daily at the close (in other words, trades the gamma). One would expect to lose money
trading the gamma and the thesis behind the index is that generally the money you lose
trading the gamma < the premium collected. Since 13 Jan, on average the opposite has been
true. Trading the gamma has been expensive because the underlying futures prices have moved a
lot day to day, which is what we are trying to capture in the realized vol numbers shown
above. The straddles are also marked to market daily using settlement prices; if implied vol
has increased, there is a further loss on the mtm. The last column in the table above shows
where current implied vol is.
