Don't be confused trading from investing, they two are different things. While trading is short-term strategies, investment holds long-term approach. That's why I argue of OP's "short period of time" in investing.
Only accept a half. They are the same thing from some perspectives, including mine. As I trader, I understand the market well and it is certain that if you consider trading as investing, there is nothing wrong. In forex trading, small traders like short-term orders, while bankers, corporations, firms are likely to put a long trade which can exist for several months.
There are two types of analysis. First, the technical analysis which you use to analyze charts, candlesticks, trends, etc. Fundamental is where you look at the overall strength such as statistics, news, politics, and evermore (for example when you analyze a project, you can look at the dev teams, the concept of the idea, the whitepaper, etc). Ironically, Both can be used in trading or investing. And wise investors (or traders) tend to make analysis so as to anticipate the outcome profit and risk.
There is nothing wrong if you differentiate trading from investing. But try to open your mind and you will observe the perspective where trading is the same as investing
