BofA's August Fund Manager Survey reveals a surge in investor confidence, with optimism at its highest since February. Cash levels have hit a historic low of 3.9%, indicating a strong shift toward risk assets. A record 91% of respondents believe U.S. stocks are overvalued, and 45% see the "Magnificent Seven" tech stocks as the most crowded trade. Despite these concerns, global stock allocation jumped to a six-month high, driven by hopes of a soft landing and future rate cuts.
