In results reflecting some of the more severe ills plaguing the banking  industry, Huntington Bancshares on Wednesday reported $52.5 million in   fourth-quarter net earnings, down 16% from last year's profits for the same   period.     
Kemper Securities' Thomas Maier said the mortgage banking operation of  the Columbus, Ohio-based company moved into a losing position in the middle   of the year. At that time, many on Wall Street revised their earnings   expectations downward.     
  
"The large mortgage banking business makes them vulnerable in two areas:  margin compression and the shrinking of the mortgage banking business," Mr.   Maier said.   
Huntington, with $18 billion of assets, has a balance sheet that is  particularly liability-sensitive, he added. Its margins underwent severe   pressure as the Federal Reserve Board hiked interest rates during the   latter half of 1994.     
  
"I expected a tough quarter for them," said Smith Barney's Henry C.  "Chip" Dickson. "They absolutely had margin compression because they have   liability sensitivity. Their loan growth is far outstripping their deposit   growth," he added. Huntington's net interest margin was 4.54% in the fourth   quarter, down from 4.89% reported Sept. 30.       
"Market conditions, especially rising interest rates, have adversely  impacted not only net interest revenue but also fee income," said Frank   Wobst, the bank's chairman and chief executive. "We anticipate similar   factors . . . to continue to influence the first half of 1995," he added.     
Huntington showed earnings for the full year of $242.6 million, up 2.4%  from 1993.
