Shares of National City Corp. have soared in recent weeks, but the  stock is not likely to maintain its altitude, one analyst says. 
Michael L. Mayo of Credit Suisse First Boston told clients Tuesday that  the company's stock is overvalued and its long-term earnings outlook   mediocre compared with its peers'.   
  
The recent performance of National City's stock suggests that it will  outperform the typical bank, but its long-term outlook is "fuzzy," Mr. Mayo   said. He downgraded the stock of the Cleveland-based bank to "hold" from   "buy."     
It closed Tuesday at $66.6875, off 81.25 cents, on news of the  downgrade. 
  
The stock has enjoyed a strong run since it announced Oct. 27 that it  would buy $2.7 billion of its own shares. The stock had gained almost 7%   since the announcement. Also fueling the stock is the smooth integration of   its recent acquisition of First of America Corp., Kalamazoo, Mich., and the   end of the GM strike. The strike dampened third-quarter earnings for many   midwestern companies.         
Catherine Murray at J.P. Morgan Securities Inc., called National City a  good stock to buy, particularly in contrast to banks that have suffered   because of their exposures to hedge funds and tumultuous foreign markets.   "It is a good, solid company with a low-risk profile that is committed to   using capital efficiently," said the analyst, who has had a "buy" rating on   the company since March.         
Mr. Mayo, however, argued that National City lacks a clearly defined  niche strategy and has lagged others in technology and product development.   National City "does not have the franchise to compete in the big leagues,"   he said.     
  
The company needs to make an acquisition, but is caught in a Catch-22,  the analyst said. The company is under no pressure to make one, but if it   does not, it will have more difficulty competing, argued Mr. Mayo.   
And the longer National City waits to make a deal, the riskier it  becomes because in 1999 the company will have to focus on making its   systems year-2000 compliant, said Mr. Mayo.   
A better investment is PNC Bank Corp., Mr. Mayo said. The Pittsburgh  company has a strong franchise and needs to take action to improve   shareholder return, said Mr. Mayo. "The mere threat of that can be a   positive catalyst for the stock."     
Meanwhile, banks stocks are losing steam as investors grow jittery about  the sector's lofty stock prices and less confident about another interest   rate cut.   
  
Investors have loaded up on bank stocks in anticipation of the Federal  Reserve easing interest rates for a third time at its policymaking meeting   Tuesday.   
The Fed cut interest rates in September and again in October, prompting  a spate of buying, which buoyed some bank stocks near or to 52-week highs. 
However, Federal Chairman Alan Greenspan cooled investors' expectations  last week when he suggested during a speech at the Securities Industry   Association in Florida that the Federal Reserve is not likely to ease   interest rates at its next meeting.
