Short Term Investments as Current Assets on the Balance Sheet. These are investments that a company plans to sell shortly or can be sold to provide cash. These short-term investments aren't as readily available as money in a checking account but they provide added cushion if some immediate need were to arise.
Long Term Investments are those when you hold your stock, assets, bonds etc for a duration which is more than a year, may be ten years or something that you intend to hold for even much longer. If you are the one who is not running after quick returns then long term investments are your cup of tea.
