share split /consolidate

Theoretically, share split and share consolidation will not affect the share price.
Just take an example. Suppose you have one-tenth of a melon. No matter how many pieces you cut a melon, your share will not be different as long as your share is unchanged.
股份合併及拆細並不會影响股份的實際價值，整家公司的估值，理論上並不會因股份合併及拆細而有分別。
舉例:
你持有 4,000股234 ，由於1拆4，由原來4,000股，變成16,000股，若股價原本$1，拆细後便等如$0.25 ($1 ÷ 4)。
但股民心理很奇怪，認為細價股好炒啲，所以有時股份拆細後，股價會上升，或股民有良好願望 (wishful thinking)，認為股份拆細代表大股東會有後著，所以投機買入。故此有時股份拆細會令股價莫明奇妙地上升，令人費解！
