By Rodrigo Campos NEW YORK (Reuters) – Apple has long been a trend-setter whose hot products attract imitators, and now its recent stock split might help revive a trend from the 1990s that has all but disappeared on Wall Street. Apple Incs move might inspire others, some believe, but only modestly. It could become a bit of a trend when you see a name like Apple decide to split the stock, said Ken Polcari, director of the NYSE floor division at ONeil Securities. Polcari said Priceline Group Inc, the most expensive single stock on the SP 500, is a prime candidate.
