There is very little doubt about the growth in Indian aviation but what has always caused anxiety among investors is certainty and sustainability of profitability. With a market share of close to 37%, InterGlobe Aviation, which owns Indigo, has emerged as an alternative given its low cost and asset light business model. That though did not stop its stock price from correcting almost 45% from its peak of Rs.1,395 in January this year to a low of Rs.725 in February. It now trades at Rs.930. While there are reasons to worry about in the short term, Indigo still remains a favourite.
