MarketWatch posted this bar chart showing the relative size of stock market vs bond market assets by category as of 2014. Roughly, it shows a total pie of about US$300 trillion invested in these “traditional assets” of stocks, bonds and loans, with roughly half in bonds, just under a quarter in stocks, and the rest in loans (both securitized and unsecuritized). This would have some overlap with the “alternative assets” of hedge funds and private equity funds invested in public stocks, bonds, or loans, and mostly leaves out physical assets like real estate and gold held directly rather than in a security.
