I hope you do not mind me joining here, but I've been watching Biocon rather closely.
Taking aside the fundamentals, I engage the market from a technical point of view. Here's my analysis on BioCon:
BioCon Daily
Price has broken a long term up trend line, connected from March 16, 2009 low. Inset shows a closer look at price action upon the break (highlighted in red). Price retested the trend line and at bar 1, bearish engulfing bar reflects the sellers momentum; this indicates previous buyers taking note of this up trend line and cutting loses.
Bar 2 is a strong bearish continuation, closing below previous swing low at 'B.'
Taking ratios into analysis, we have a possible AB=CD completion with D point at 310 - 331.50 area (green highlighted). The area, if you look left, is a former rectangle consolidation before the break out to 472.55 high.
Am watching for possible support at this area to long, but am watching 357.5, which is previous B swing point for possible resistance; any resistance at 357.5 will likely indicate a down trend continuation.
