To The Moon

Citi is out with a screen for "significant downside risk or upside potential" based on crowding.

Citi measures crowding acrossquants, fundamentals, hedge funds and multi-strat macro funds using five metrics: the most crowded quant factor ranking (region specific), historical relative valuation, short interest, concentration of sell-side analyst ratings and macro risk contribution in individual stocks.

"Conventional thinking is to avoid buying crowded stocks (high crowding composite), as they may become harder to attract marginal investors, while stocks that are less crowded are prone to react more positively to fundamental catalysts, as they can attract a larger set of new investors," Citi says. "However, we do not intend the crowding composite to be a buy/sell signal by itself."
