Investors' love affair with bank stocks has noticeably cooled in recent  months. 
The mania for electronic commerce shares, combined with the absence of  banking megamergers and a series of unclear fourth-quarter earnings   reports, has tempered enthusiasm for virtually all financial stocks.   
  
It's a stark change from the days when the word "bank" had the panache  that ".com" carries today among investors. 
"Three or four years ago, if a company had the name 'bank' in it you  made money on the stock one way or the other," said Scott Edgar, director   of research at SIFE Trust Fund, which invests primarily in financial   stocks.     
  
"Either earnings would be good and the stock would rise, or they'd fall  short and the company would get taken out. That dynamic certainly does not   exist now, and it doesn't appear it will return in the immediate future-not   until after 2000."     
Bank stocks have lagged the market since the Standard & Poor's 500 hit  its 1998 low on Aug. 31. Since then the S&P 500 has risen 30.4%, while the   S&P bank index has risen only 14.3%.   
Banks led the market downward Thursday, with the S&P bank index falling  2.7%. The Dow Jones industrial average fell 62.3 points, to 9304.5. 
  
Banks have failed to snap back from last summer's selloff as quickly as  the rest of the market, because investors see few ways for banks to   increase earnings, outside of mergers.   
"It's not a bullish sign when it looks like the only way to grow  earnings is by increasing market share. That can't go on forever," said   Arthur Hogan, chief market strategist at Jefferies & Co.   
Merger fever has subsided almost entirely since last July. With bank  stocks performing poorly, bankers are reluctant to use them as currency to   finance costly acquisitions.   
Until merger mania returns, Mr. Hogan said, bank stocks are likely to  return to more traditional earnings multiples. 
  
But what should those multiples be? Bank stock multiples are typically  one-third lower than the average company on the S&P 500. With the average   S&P 500 stock trading for 33.7 times earnings, investors find it hard to   justify paying a multiple in the mid-20s for stocks as sensitive to   domestic and foreign economic fluctuations as banks.       
Until the market sorts out which stocks are inflated in price and which  are fairly valued, some pros are advising investors to step back a bit from   stocks. On Thursday, J.P. Morgan & Co.'s market strategist Douglas Cliggot   recommended that investors reduce their exposure to stocks to 50% of their   portfolio. His previous "model portfolio" had allocated 60% to stocks.       
Even usually active players like Mr. Edgar are sitting on the sidelines.
Mr. Edgar said he likes such stocks as Bank of New York Co. and Wachovia  Corp., but would hesitate to buy much until the market settles down and he   can better gauge which companies are undervalued.   
That said, the outlook for bank stocks is better than for many other  sectors, Jefferies' Mr. Hogan says. 
"Banks are going to continue to make money. It's not like the oil  stocks, which aren't doing well because people aren't using the product   like they used to. People are still going to banks," he said.   
Among the few financial stocks showing any signs of life nowadays are  brokerage stocks, which have revived from last year's doldrums because of   investors' frantic search for anything related to electronic commerce.   
For example, shares of Southwest Securities Group, a Dallas-based firm  whose subsidiaries include an on-line brokerage, have risen 132% since Dec.   24. Its stock closed at $35.125 Thursday.   
But though the market may consider this company a "technology play,"  Southwest gets most of its revenue clearing trades for other firms, said   spokesman Jim Bowman.   
Mr. Bowmnan said he didn't mind that investors value his company like an  Internet stock. "It's nice when something like this happens," he said.
