Ghost of Friday 13th is very much apparent today in world market. Every market is down with no concrete reasons. Many argue about Infy result causes Nifty down. But may I ask them if it was so, why Nifty did not plunge as soon result was declared. Why Nifty plunged in late afternoon, when it seems everything is fine, and market has discounted Infy result. Anyways, Nifty has respected the lower level of the channel of 100 points.
