The capital market is a market for various long-term financial instruments that can be traded, whether bonds, equity (stock), mutual funds, derivative instruments or other instruments. Capital market financial function is to provide funds needed by other parties without having to be dir ectly involved in the company's operations (Husnan, 2005). Stock is one of the most investment instruments offered by the company and most in demand by investors because the stock is able to provide higher profit levels than other investment instruments and with a higher level of risk. According to Amanda and Wahyu (2013), banking stocks are the most popular stocks and have reportedly outperformed the growth of the Jakarta Composite Index (IHSG), although in mid-1997 and in the 2008 global financial crisis the banking sector fell and experienced a decline in performance. Over time, the banking sector is able to prove its existence in performance and achievement of good results so that investors are interested in buying shares again. Stock price is one indicator of the success of corporate management, if the stock price of a company always increases, then investors or potential investors judge that the company managed in managing its business. This will make investors more selective and more cautious in taking stock investment decisions in the banking sector.The development of the capital market is one indicator that continues to be monitored starting from the transaction value and transaction volume, market capitalization, the number of issuers, and the Composite Stock Price Index (IHSG). The movement in the capital market is strongly influenced by the expectations of its players formed by a combination of fundamental, technical, and sentiment factors. If there is a positive expectation, interest in buying will increase which will move the price up. Conversely, negative expectations will drive prices down as selling pressure increases.
