Thacker told CNBC-TV18, "We have liked Tata Chemicals for some time now; it’s just broken out of what we call as  bullish cup and hand formation. I think this would do very well for the next few days for the stock price. I expect the  stock to head towards targets of about Rs 460-470 in the short-term and long positions can be taken with a stop loss  below Rs 425."

This recommendation came just one day before the big fall! And here is how the chart looked on the day this recommendation came

So either that analyst doesn't understand what Open Interest is - or its a deliberate attempt by TV folks to mislead 'aam admi'

From OI table even an average trader like me would have suspected that the rally was running on tired legs or no legs!
