发帖数: 354 | 1 现在在做股指期权定价，用OVME pricer可以看到一个bloomberg volatility.对于每一
个买入日，每输入一个不同的到期日和一个不同的moneyness就会有一个新的vola. 我
想问的是，对于每一个买入日，有没有一个整个表格式的volatility surface呢？我查
到了一个，比如说30day_impvol_100%_moneyness,这是一个可以输到excel去的表格，
但是我对比了一下这个表格里的vola, 在同样的设置下和OVME定价器里的数字并不完全
一样，这是咋回事啊? OVME里的bloomberg vola是怎么来的啊? 恳请牛人们不吝赐教。 |

发帖数: 354 | 2 help desk 也提示了这个，但和ovme里生成的vola还是不一样。 我还来决定采用ovdv
了，谢谢你的回答 |

发帖数: 7033 | 3 已经由BS模型求出一系列implied volatility 的离散点（比如newton法求得），希
望拟合出整个implied vola 曲面，有哪些方法？各有些啥优劣，及检验标准如何。
另外，基于这个得到的implied volatility surface，可以制定什么option组合，
或者交易策略？
现在写一个报告，缺乏金融背景，看得不甚明白。希望懂的人指点一二啊。。。或
者推荐看一些文章和文献也好。谢谢了。 |

Michigan's freakishly warm March followed by overnight freezes in April
devastated many of the state's largest fruit farms.
Cherries bore the brunt of Mother Nature's whiplash. The state, which
produced 70.9% of the nation's tart cherries in 2010, is expected to harvest
a mere 2 million pounds of tarts this year, down from 135 million pounds in
2010 and 266 million pounds in 2009, according to the Michigan Frozen Food

发帖数: 8496 | 6 I 've seen a news program a few months ago (maybe ABC 20/20?) that they set
up an ipad leaving it at airport TSA check point and experiment what would
happen. Their hidden camera recorded that a TSA agent took it but Ipad had
not shown up at lost & found for days. So they turned on the home-ing
software and followed the signal to a house miles away. Vola, the house
belongs to a TSA agent and the news got the agent fired. |

Thank you very much for helping me answering my question. I was doing
research myself and figuring out the issue. You are right. I rewrite the
query to get rid of cursor and use PATH XML instead.
One interesting thing I observed is that after I updated my sp and run the
report, it gave out an error msg:
"An error occurred during local report processing.Exception has been thrown
by the target of an invocation. String was not recognized as a valid
DateTime.Couldn't store <> in Stmt_Date_Cre... 阅读全帖 |

你这个就有点离谱了。一般用cubic spline做vol surface，出来的surface不一是
arbitrage free。但你基于自己建的vol surface，制定什么交易策略有什么用？回家
交易arbitrage自己东家？ |

我就是想先有个大概的方向好看书。 |

发帖数: 7033 | 14 这个是别人跟我说的大概的报告方向，所以我也不是很明白啊。
我还是一步步做，先拟合出vol surface吧。。 |
