SERPs.com has quietly launched a SERPs Volatility Index, which aims to work like the MozCast tool to track search results fluctuations and help webmasters know if there was an algorithm update at Google and Bing.
Nifty continued its consolidation above 8500 in the last week. The weak set of results from IT heavyweights checked the momentum. The volatility index declined marginally last week due to open interest addition coming into both 8500 Put and 8600 Call strikes. Move above 8600 may cause another round of short covering from Call writers
