Flow variables refer to variables that are measured over a period or per unit of time. Stock variables, on the other hand, mean those variables that are measured at a point in time. The concepts of stock and flow are variables that have mutual dependence both to each other as well as to other variables.

What is investment stock variable?

Is wealth a stock or a flow?

The basis of distinction is measurability at a point of time or period of time. Be it noted that both stocks and flows are variables. A variable is a measurable quantity which varies (changes).

What is flow variable?

What is the dependent variable in a stock market model?

The dependent variable in a statistical model for stock investors is usually the stock's price. Since investors are primarily concerned with the value of shares, most models try to predict what the share will be worth in the future. There are exceptions, however. An analyst may desire to know how many shares will change hands, in which case the dependent variable becomes the trading volume. In other cases, analysts try to predict a value called volatility. Volatility measures how wildly the stock's price changes and is therefore a good predictor of risks associated with holding that stock.

What is volatility in stocks?

In some instances, the analyst uses the price of one stock to predict that of another.

What is dependent variable?

Since stock investors often rely on statistics, you may hear such terms frequently in research reports. What a particular analyst will define as the dependent variable varies based on the model used.
