The soil, the seed and the plant

Equity markets are driven by liquidity. This is a somewhat fancy way of saying that unless there's a net amount of money flowing into the markets, stock prices in general will not go up. If this is true, then obviously, the converse is also true. When there is no net money coming into the markets, then they are stagnant and when there is net money flowing out of the markets, then they fall. All this is self-evident. In fact, saying that there is money flowing into the markets so they are rising is almost a tautology. It's just the same thing said in two different ways. As practical investors, it is more important to know, if possible, why there's money flowing into the markets, what kind of stocks is it coming into, what is the future perspective
