I wouldn't buy HEB now. Highly speculative, but I got in a couple of weeks ago and now i'm up 78%. I cashed out half the shares at 128%, so the rest is there as a gamble on the FDA approval or not.
I would buy TMT now. The stock finished flat at Rs 1.05 with huge trading volumes of 7.12 lakh shares as against Tuesday's trading volumes of 3.90 lakh shares. TMT stocks witnessed heightened activity trading though price wise they display ed a flat trend.
