"In real terms, though, FMCG segments seem to be faring better than discretionary categories, where growth has now dropped even below historical lows. While one might wish to bank on the resilience of FMCG, past data suggest that nearly all consumer companies suffer badly in a prolonged slowdown of the kind we are witnessing now," the report added.
"This is particularly true for paints and the smaller FMCG firms that have grown earnings far ahead of the sector in recent quarters. Margin gains in paints could likely sustain given the nature of the industry," it said.
However, it is cautious on the margin trajectory for the smaller FMCG companies, as it expects them to pass on the benefits of benign commodity in a weak demand scenario. The report also noted that despite lingering slowdown, valuations for companies continue to be high.
