The S&P 500 has significantly underperformed compared to European and Chinese markets, gaining only 3% since January, while the STOXX 600 and Hang Seng rose over 9% and 14%, respectively. Future flows to Wall Street may hinge on geopolitical developments, particularly the Ukraine ceasefire talks, and the upcoming Fed meeting in March, which could signal shifts in monetary policy. A breach of the S&P 500's recent high of 5,100 points may initiate a new bull rally, supported by increasing buying pressure.
