Citigroup: Investors turn bullish, and short positions face risks.

Citigroup strategists noted that in the past week, the positions in the European and American markets have shown signs of recovery, putting pressure on short sellers, particularly evident in the S&P 500 index. The relevant team stated that last week, investors in both markets injected new funds, rather than merely closing short positions. In the American market, the recent rise has led to continued losses for short sellers; the large short positions in the S&P 500 could face forced buybacks if the market continues to gradually rise.
