The market hit a bright spot straightaway today as the Sensex moved beyond 31,000 at the start, extending its weekend gains following the GST kick-off amid mixed Asian cues. However, growth of eight core sectors slowed to 3.6 per cent in May dragged down by coal and fertilisers, which acted as a sobering factor. The 30-share index, after soaring 337 points to touch high of 31,258.33 at the outset, let go of some gains and traded at 31,069.20, up 147.59 points, or 0.48 per cent.
