When engaging in financial markets, there are two main types of positions to consider: long and short. A long position refers to buying an asset with the expectation of selling it at a higher price in the future. On the other hand, a short position involves selling an asset with the intention of buying it back at a lower price. Both strategies involve predicting the direction of the market and can be used for various purposes, such as hedging or speculation. Understanding these concepts is crucial for successful financial decision-making.
