seems to have stabilized. After shares spiked to nearly $40 late Thursday, they have settled back down around $38 -- up more than 9% from a week ago and up almost 17% in the last month.

But I'm here to tell you it's the end of the line for BP, and investors who made a gamble and jumped in during the worst of the Gulf oil spill should cash out their profits now and put those gains to work elsewhere.

I know, by selling BP now, I'm going against conventional wisdom. But I went against conventional wisdom

when I recommended investors buy BP at $32 with a target of $37. Now that this target has been hit and we've seen a quick 16% profit, here are four clear reasons why the oil giant is set for another spill in share prices:

The stock's big run

over the last week was fueled in part by hope over the newest effort to cap the broken well. Now that that has actually happened, the glow of that success will fade quickly as the focus returns to the massive cleanup effort. We're already hearing about pressure fears causing seepage on the ocean floor, so it's hard to believe the optimism of the cap will last.

The rumor mill is wrong.

The stock's rise is also due to rumors of a takeover or sale of some assets. It has also been rumored that BP is in talks to sell off parts of the business to help pay for Gulf cleanup costs. Reports also suggest that

plan to make a bid for BP. But I just don't see that happening right now. There is far too much uncertainty over the company's massive liability claims for a potential suitor to jump in now.

Another round of hideous PR is on the way.

The Presidential panel tasked with investigating the BP spill and subsequent cleanup started hearings this week, and they will continue for months. The PR will be terrible as the entire spill ordeal -- and BP's handling of it --will be dissected in front of the cameras.

Things are about to get ugly

when it comes to claims against BP. There is a firestorm brewing over the way claims are being handled. Last week, the company reduced payments on 40,000 claims over incomplete paperwork and more than half of all claims haven't yet been processed. Expect criticism to ratchet up in the weeks ahead.
