Icahn Enterprises L.P. (NASDAQ:IEP) stock remains under pressure following the Hindenburg short report. Shares have now pulled back 60% from the level shares have been at over the last couple of months. Bill Ackman from Pershing Square Holdings (OTCPK:PSHZF) has added to the selling pressure seen in IEP via comments he made this week. IEP's dividend yield has soared to an extremely high level - but the dividend is still not covered by profits, which is why income investors should not blindly rush into this stock.
