?pwd=1234 Extraction code: 1234?The development history of leveraged funds can be traced back to the 1950s. The earliest leveraged funds were created in the United States to increase investment returns by borrowing funds. However, these funds suffered a series of setbacks in the 1960s due to the risks of leverage. As regulatory policies adjusted and investor demands changed, leveraged funds re-emerged in the 1980s and continued to grow in the following decades. Nowadays, leveraged funds have become one of the important investment tools in the global investment market.
