Having a finger on the pulse is vital to concluding your research on a sector. This includes catching onto a sector's growth headwinds, market maturity (where the sector is in its cycle), consumption split between organized versus unorganized market, consumption split between domestic and international players, split between the consumption in domestic and international markets, the players responsible for setting the trend in the sector (in terms of pricing power, product innovation, etc), the emerging players that could disrupt the set trends, the barrier to entry faced by new players, and so on. Look, it's impossible to list such things down here, specially since different sectors can have different things to look at, but the gist is to have an eye on what the participants of a sector as a collective are doing.
