Usually, the rise in inflation causes investors to react in a negative way thinking that the company is holding back on spending which eventually decreases the stock value. When there is deflation which is caused by the drop in prices investors usually see it as assign of the weak economy and this also leads to a stock market price drop.

Rate of Interest
The rate of interest established by banks and governing boards can also affect stock market prices. A higher rate of interest indicates that money will be becoming expensive for borrowing stocks. For coming up with higher interest rates companies usually cuts spending or layoffs workers. A higher interest rate also forces the companies to limit the amount of money they used for spending which could adversely affect the earnings. These effects due to higher interest rate usually cause a drop in stock market prices.

Foreign Markets

This is due to the fact that when foreign markets are down companies which are selling products and services to foreign countries will find it difficult to sell the same amount which leads to falling of stock prices in the home market. Due to ripple effect also there will be the drop in prices in the stock market.
