Markets shaky, but stay marginally in the green

The Sensex and the Nifty are trading in positive territory, although the deepening Greek crisis is taking its toll, and not much strength can be seen in the market sentiments. The 50-share Nifty index reclaimed its crucial psychological level of 8,350 during trade, but saw selling at higher levels. The index soon retreated and was testing 8,300-level.
