Shares of Chesapeake Energy Corp., the U.S. fracker preparing for a potential bankruptcy, are experiencing another wild session, plunging as much as 74% before trading was halted again on Tuesday. The stock was initially prevented from trading for more than three hours after the market opened, only for circuit-breakers to be triggered once more after the resumption of buying and selling. Having jumped 182% on Monday, the shares touched a low on Tuesday of $18.41.

Chief Executive Officer Doug Lawler is seven years into an effort to untangle the financial and legal legacies of Chesapeake’s late founder, Aubrey McClendon, who took on debt to pursue aggressive drilling programs.
