How do I compare implied and historic volatility? @vonjd I have found the following two papers to be interesting wrt to this question as well: bcb.gov.br/ingles/estabilidade/2002_nov/ref200201c62i.pdf and rbnz.govt.nz/research/discusspapers/dp02_04.pdf |

How do I compare implied and historic volatility? thanks for the links to the paper and the book. So there is no point in trying to compare the skew and kurtosis of the historic distribution, to the risk reversal pricing and smile of the curve, analagous to how macro traders will compare historic with implied ATM vol? That's what I was wondering basically. Second, what do you mean by overlapping data? I am using bloomberg "last price" closing prices, so there should be no overlap? For completeness I take log returns of that series and multiply by sqrt(262) to get the annualized vol. What would you do differently? |

How do I compare implied and historic volatility? @vonjd no with Excel. I am shamed to say that I while I am an experienced trader and programmer, I am not a quant, and am only beginning to learn R. So the data comes from Bloomberg, which gives the ATM, RR, and flys for each tenor and delta and I have backed out the outright vols for each point. |

Monthly data for popular indices (constituents). @Terco I have a spreadsheet that will do this if you like. It only does a few months, you'd have to fill out the other months by copying and pasting the formulae. You'll need access to the Bberg terminal though, with Excel and the add-in. Email me at lagunafinance at me dot com if you're interested. |

How do I eliminate developed currency funding cross rate risk in an EMFX position? @moderator: How can I start a bounty on this question? It doesn't seem to be letting me do so. |

What concepts are the most dangerous ones in quantitative finance work? Actually, we can turn this argument on its head. We can profit from the fact that correlation vanishes during a crisis, by selling correlation to the street. Fact is because many retail investors don't want to choose specific assets in an asset class, they tend to buy baskets. Since they also want capital protection, they tend to buy options on those baskets. Writing these options takes the street short the correlation of the basket elements, and they're happy to pay up to buy it back at (usually expensive) levels, which is what many Hedge Fund traders do through dual binaries and such like. |
