Aviation stocks SpiceJet and InterGlobe Aviation (IndiGo) have rebounded 8-23 per cent since their lows in March. The gains came on the back of a market rally, expectations of a relief package by the government, falling crude oil prices, and renegotiation of lease rentals. Investors, however, should be cautious, given a weak outlook for FY21 and higher fixed-cost structure of the airline industry.
