There are three predominant market movers, according to this posting by the CEO of Ralston360, a blog from an advertising and design firm:
“There are certain journalists that can move a market.
“Jim Cramer of Mad Money can move a stock 30% overnight by making a strong recommendation as he did last Friday with his recommendation to by NMT Medical.
“Walter Mossberg of The Wall Street Journal can move a tech product like the iPod with a positive review in his weekly column.
“But, I have never seen one person move a market like Robert Parker and the 100 point rating system in his wine newsletter The Wine Advocate. Parker can single handily drive a wineryâ€™s product to double in price and to out-of-stock in days with a glowing review. He can also make or break the sales of the entire Bordeaux wine region with his views on the quality of a single vintage.”
I think there are others in the business journalism profession who can move markets. Alan Abelson of Barron’s leaps to my mind.
