Abstract
This study aims to examine and analyze the effect of funding decisions, investment decisions, profitability and firm size on firm value at LQ 45 listed on the Indonesia Stock Exchange. This research is an associative research. The data collection method used is the Sample Survey method using secondary data sources in the form of quantitative data, namely annual financial reports obtained from www.idx.co.id. The results of the panel data regression analysis show that financing decisions proxied by the Debt to Equity Ratio (DER) have a positive effect, but not significantly to firm value. Meanwhile, investment decisions proxied by the Price Earning Ratio (PER) have a positive and significant effect on firm value. Profitability proxied by Return on Assets (ROA) has a positive but not significant effect on firm value, while firm size (Size) has a negative but not significant effect on firm value. It is hoped that this research can be taken into consideration by investors in making investment decisions.
