Schwab's Liz Ann Sonders,it would be no good for the U.S. stock market to get a hyperbolic peak

Schwab's Chief Investment Strategist Liz Ann Sonders notes that although there are differences, ''there are many more similarities between today and the mid-1990s. It's a signal we are likely in the more mature phase of both; a phase when individual investor participation heats up and when the economy more clearly moves from recovery to expansion. But a note of caution: remember that ultimate melt-up did not end well at all. A better scenario this time would be for the market to continue pacing the mid-1990s market, but without the blow-off top in 1999-2000''
