Oct 20 (Reuters) - U.S. stocks were flat to lower by late afternoon Tuesday as a drop in healthcare and biotech stocks offset gains in United Technologies and Verizon.
A 5.6-percent drop in IBM also weighed on the market. The stock hit a five-year low after it reported a bigger-than-expected fall in quarterly revenue and cut its full-year profit forecast.
The S&P healthcare sector fell 1.3 percent, dragged down by Allergan and Pfizer.
"You're seeing weakness in momentum names in general. Obviously the healthcare names are under pressure again, especially pharma companies," said Michael O'Rourke, chief market strategist at JonesTrading in Greenwich, Connecticut.
Stocks have mostly gained this month following a selloff in the third quarter, though concern about third-quarter earnings has added to caution in recent sessions.
Among those companies beating analysts' expectations, United Technologies rose 4 percent to $95.88, giving the Dow its biggest boost.
Also on the plus side, Verizon's shares were up 1.3 percent at $45.27 after the largest U.S. wireless service provider reported better-than-expected revenue and profit.

Of the S&P 500 companies that have reported so far, roughly 40 percent have beaten revenue expectations, below the long-term average, according to Thomson Reuters data.
Travelers rose 2.6 percent to $109.04. The insurer's quarterly profit topped estimates, helped by higher underwriting gains. Harley Davidson skidded to a two-year low at $47.02 after the motorcycle maker cut its full-year shipment forecast.
Shares of Tesla dropped 8 percent to $209.77 in heavy volume after Consumer Reports magazine found that advanced fuel-saving technology and digital multimedia systems in vehicles including the Tesla Model S sedan are hurting reliability.
