JPMorgan Chase paid its chief executive, Jamie Dimon, $27 million in 2015. In another Wall Street universe, the hedge fund manager Kenneth C. Griffin made $1.7 billion over the same year.

Even as regulators push to rein in compensation at Wall Street banks, top hedge fund managers earn more than 50 times what the top executives at banks are paid.

The 25 best-paid hedge fund managers took home a collective $12.94 billion in income last year, according to an annual ranking published on Tuesday by Institutional Investor’s Alpha magazine.

Those riches came during a year of tremendous market volatility that was so bad for some Wall Street investors that the billionaire manager Daniel S. Loeb called it a “hedge fund killing field.” A few hedge funds flamed out; others simply closed down. Some of the biggest names in the industry lost their investors billions of dollars.
