** KBC Securities downgrades Belgian investment holding Ackermans & van Haaren ACKB.BR to "accumulate" from "buy", citing limited upside after a recent strong share price rally
** Up to Monday's close of trading, the stock rose 22% YTD
** The broker lowers its forward valuations for the firm's private banking units, Delen and Bank Van Breda, due to a compression in forward peer multiples
** The brokerage raises its PT by 10.3% to 300 euros, which represents only a modest potential from current levels, no longer justifying a "buy" rating
** KBC notes the stock now trades at a premium to KBC's estimate of its NAV after a strong fiscal year
** Out of eight analysts, five rate the stock "strong buy"/"buy," and three rate it "hold" - LSEG data
** Shares in Ackermans fall 3.7%
