Taobiz explains Term
The life of an asset or investment generally falls into one of two main categories: short term and long term. An investment can be held for a very, very short period of time - for instance, a day trader might buy and sell a stock within seconds. On the other hand, the life of an investment can be as long as the life of a piece of land, which can span several generations and pass through the hands of many investors.
