NEW YORK (

TheStreet

) -- A wealth of healthy buying in recent weeks led a variety of blue chips to hit fresh

52-week highs

on Tuesday -- many for the second consecutive session -- including technology darling

(AAPL) - Get Report

and Dow Jones industrial average components

Caterpillar

(CAT) - Get Report

(DD) - Get Report

and

Kraft Foods

( KFT).

Jim Cramer told the viewers of his

"Mad Money"

TV show last week the

52-week high list

tells us everything we need to know about the market, though it's not the number of companies hitting 52-week highs that's important, it's the number of industries represented on the list.

He explained that just a month ago, there were only three industries on the list, and they represented people's fears of the market. But today, there's an astounding 25 different industries represented, a diverse swath of our economy.

Ranked by volume, the most heavily-traded stock to hit a fresh 52-week high Tuesday was
