Investors who trade stocks on the Internet could yield some savings next month. Charles Schwab, the biggest discount and online brokerage has announced that it will waive all commissions on online dealing in British quoted shares for the month of July. Schwab has said it will forgo commissions, which range from £15 to £75 depending on the size of the deal for certain transactions. The decision follows news that Merril Lynch will shortly also move into Internet broking. Increased competition should make it more attractive for investors to use this medium in the future putting pressure on commissions and fees charged.
