Tatacomm, ratio analysis & study of financials

I went through some stock recommendations on net. Both the recommendations are negative to Tatacomm. One had downgraded it to 'SELL' from 'NEUTRAL'. Other had made it 'UNDERPERFORM'. It was said that Tatacomm has high debt-to-equity ratio. It is such a debt-ridden company that even when sensex is jumping by 500 points, it continues to tumble down. It was wrong decison to do intraday trading in such a risky stock. This signifies the importance of ratio analysis & reading through annual report. I think I should learn these skills first before doing further trades. My study of Tatacomm equity was insufficient, when I decided to do day trading in Tatacomm.
