  • High call for with restrained delivery tends to boost inventory prices.
  • High supply with restricted demand tends to lower inventory prices.

This ongoing tug-of-war influences every rate fluctuation you see on a inventory chart. For example, if a agency releases super quarterly income, more buyers will need to shop for the stock, growing demand and pushing the price up. On the flip side, if poor news hits — such as a lawsuit or declining revenue — buyers might also rush to sell, growing deliver and pushing the rate down.
