According to a new note from Bloomberg, CalPERS' board is meeting for a workshop today in Sacramento to discuss asset allocations for the upcoming year which could include a doubling of the fund's bond allocation from 19% to 44% which would be funded with a massive $50 billion sell down of equities.

Calpers is looking at a menu of options for its fixed-income target ranging from the current 19 percent to as much as 44 percent, according to a presentation for a board workshop in Sacramento coming up Monday. Equities could be cut to as little as 34 percent from 50 percent. Stocks were the best-performing asset class in fiscal 2017, returning almost 20 percent.

"The markets have had a pretty good run and it's possible Calpers staff is thinking this might be a good time to lock in some of the gains," Keith Brainard, research director for the National Association of State Retirement Administrators, said in a phone interview.
