Bank of America
Monday brings the end of a six-year lock-up period, permitting the bank to sell the shares. The stake has been valued at about $17 billion.
The bank has been holding talks with sovereign wealth funds that might buy its shares.
A sale of the stake could raise additional capital the bank needs. On Thursday, the Bank of America said it would receive $5 billion from Warren Buffett's Berkshire Hathaway in exchange for preferred stock and warrants.
A Bank of America spokesman declined to comment.
Bank of America shares were up 2.1 percent in midday trading.
