Company income information has very important role. Many investors it as the

This thesis aims to analyze the company's income information as the stock
price indicator, whether the publication ofcompany's incomecan cause the stock
price around the publication date, and also identify whether the investor get the
abnormal return from it. This is also known as the event study. In this research,
the companies will be analyzed in two groups; companies that can fulfill the
investor's expectation and companies that can not fulfill the investor's
expectation. The companies can fulfill the investor's income expectation if the
actual income (publicate net income) is bigger than the investor's income
expectation. Investor's income expectation or the income expectation is calculated
using trend analysis. Trend analysis is use because the independent variable is
time so the result of the income expectation can be known before the actual
income.
The result of this research shows that the companies that can fulfill the
income expectation are follow by a significant positive market reaction. It can be
seen by the increasing abnormal return and the probability (sig-t is lower than
0,005) on several days after the announcement period. On the other hand, the
companies that cannot fulfill the expected income is also following by a negative
market reaction. It can be seen from the decreasing abnormal return before and
after the publication date.
