Bulls, Bears: Individual investors will get a chance to compare notes on Wall Street's phenomenal 1995 bull market Saturday when the National Assn. of Investors Corp.'s Los Angeles-area council holds its annual Investors Fair. The NAIC, the umbrella organization for investor clubs nationwide, holds the fair partly to spread the word about the club investing concept--a way for novice or veteran investors to pool time, effort and money in researching and buying stocks. The all-day fair will include round-table discussions on investment topics and presentations by several companies, including Agouron Pharmaceuticals and banking giant Synovus Financial. Registration is $30 at the door and seating is limited. The fair will run from 7:30 a.m. to 4:30 p.m. at the Proud Bird Restaurant, 11022 Aviation Blvd., near Los Angeles International Airport. For more information, call (310) 326-8150.
