Updated from 9:20 a.m. ESTDespite attempts by General Electric ( GE) to distance itself from the financial troubles of another diversified manufacturer -- Tyco International, ( TYC) -- analysts say investors are right to ask questions about the company and, indeed, any large conglomerate with diverse business lines. General Electric reiterated Tuesday that it is on track to meet first-quarter and full-year estimates, saying it has a "system of controllership" that is "second to none," with "tremendous financial strength." The firm said earnings should grow 17% to 18% this year to between $1.65 and $1.67 a share. GE is also confident that first-quarter earnings will meet or slightly exceed consensus estimates of 34 cents a share. "GE isn't a 'faith' stock -- it's a performance stock. And we're on track for another record performance," CEO Jeffrey Immelt said in a statement. Shares of General Electric have fallen 11% since the start of the year as investors shied away from large corporations, fearing they are more vulnerable to accounting scrutiny.
