A stock split happens when a listed company divides its existing shares into a larger number of shares, typically to make them more affordable for retail investors and attract greater market participation.
Conversely, a consolidation or reverse stock split reduces the total number of shares while raising the share price. Companies often do this to meet the minimum share price requirements of certain exchanges and avoid delisting.
Your existing position will be closed at a price of zero, after which a new trade will be opened reflecting the revised number of shares based on the terms of the split or consolidation.
