What makes stocks go up?

In terms of liquidity, since a penny stock has fewer shareholders, it is less 'liquid', meaning it will not trade as many shares per day as a larger company. Any sudden change in demand or supply of stock can lead to a lot of volatility in the stock price. This lack of liquidity can send a stock price soaring up quickly or come crashing down. Lack of liquidity and volatility also makes penny stocks much more vulnerable to manipulation by management, market makers, or third parties. A lack of liquidity can also make it extremely difficult to sell a stock, particularly if there are no buyers that day.
