Eddie Lampert And His Hedge Fund Have Lost A Combined $236 Million On Sears Today

Shares of retailer Sears got pummeled on a Bloomberg News' report that a "medium sized" vendor had halted shipments.

The stock was last trading down 15% at about $25.72 per share.

This is more bad news for billionaire hedge fund manager Eddie Lampert.

Lampert-who runs Florida based ESL Investments and is the chairman/CEO of Sears-has spent years trying to turnaround the beleaguered big-box retailer.

Lampert is also the largest individual shareholder the retailer. So far, the investment has been a disaster.

According to data compiled by Bloomberg, Lampert last personally held 25,226,096 shares, or about 23.69% of the company's stock.

That means Lampert has lost about $115.5 million on his Sears investment since yesterday's close.

RBS Partners, which is managed by ESL Investments, last held 26,438,272 shares, or 24.83 percent, data compiled by Bloomberg shows.

Since yesterday's close, the fund's stake has lost $121.08 million, according to our calculations.
