Investing is something you do after complete and thorough evaluation and due diligence has been performed. You develop an opinion about the idea and then wager a portion of money to the long term hope of the asset increasing in value. The time frame is normally much longer than a trade.
Some of the things considered when investing are the balance sheet, debt, growth multiples, earnings and its growth rate, safety, and more. The time can be very considerable to properly vet a good investment. After investing normally you are prepared to weather the good and the bad times and just hold the position no matter what unless something very fundamental changes in the business.
