For example, if I "short" an asset, my portfolio value will increase as this asset price is decreasing.
Pretty useful if I anticipate it to decrease and want to make money out of it (or be "insured" against it). https://t.co/CAsstXKbVZ
例如，如果我“做空”一项资产，我的投资组合价值将随着该资产价格的下降而增加。
如果我预计它会减少，并想从中赚钱（或“投保”它），这是非常有用的。https://t.co/CAsstXKbVZ
