Financial Economics is a branch of economics that analyzes the use and distribution of resources in markets. Financial decisions must often take into account future events, whether those be related to individual stocks, portfolios, or the market as a whole. The goal of financial economics is to make sound financial decisions by predicting future events and trends.One important application of financial economics is portfolio management. A portfolio manager must carefully select which assets to include in a portfolio in order to achieve the desired risk/return trade-off for their clients. Additionally, they must continually monitor their portfolios and rebalance them as needed in order to maintain the desired risk/return profile.Another key area where financial economics plays an important role is corporate finance. In particular, firms need to make decisions about how much debt vs equity financing to use when starting or expanding their businesses. Additionally, firms need to be aware of how changes in interest rates or exchange rates can impact their bottom line.
