Hedge
Risk Management
どういう意味か
A position opened to offset the risk of another position. If your main trade loses, the hedge should gain, reducing the total damage.
例
You hold $50,000 of long SPY and buy a $500 put option that pays off if SPY crashes. If the market drops 10%, your long loses $5,000 but the put gains about $4,000, softening the blow.
初心者がよくやるミス
Beginners hedge every trade and watch their gains evaporate into hedge costs. A hedge is insurance -- it has a price; over-hedging guarantees you cannot make money.
