Since our current economic environment is getting more and more competitive, enterprises must continuously improve and strengthen their ability in order to maintain their competitiveness. Therefore, investment activities of firms are the key elements to drive business growth. This article tries to discuss whether three different investment dimensions can help to boost firm¡¦s future growth of profitability. This research uses investment spending of listed firms in domestic electronics industry (including capital expenditure, intangible assets and R&D expenditures) as variable to explore the effects of these three investment expenditures on corporate P/B ratio as well as ROA (Return on Asset). This study attempts to analyze whether firm¡¦s investment activities can impose significantly positive influence on its future profitability. We use panel data to run regression analysis and further divide Taiwan electronics industry into five sectors to analyze the effects of firm¡¦s investment expenditure on P/B and future profitability among different sectors. The empirical results show that investment spending imposes significantly positive effect on firm¡¦s profits, but this relationship exist time lags.

Bakgrund Värdeinvesteringar bygger på att handla lågt prissatta tillgångar i förhållande till värde. Många har under åren formulerat olika strategier för att identifiera underprissatta tillgångar. Särskilt populärt är strategier baserade på att handla bolag med låga nyckeltal såsom P/B- och P/E-tal. Dessa strategier visade i flertalet studier förmågan att generera riskjusterad överavkastning på 80- och 90-talet. Just dessa strategier har dock visat upp sämre resultat i senare studier gjorda på 2000-talet. På den svenska marknaden har riskjusterad överavkastning mellan åren 1980-2010 uppvisats. Det har dock förblivit obesvarat hur resultatet hade blivit på den svenska marknaden efter 2010. Syfte Syftet med studien är att analysera i vilken utsträckning en värdeinvesteringsstrategi baserad på P/B-, respektive P/E-talet, genererar riskjusterad överavkastning.   Metod Studien har antagit en kvantitativ strategi med en deduktiv ansats. Genom en tidsserieundersökning har portföljer skapats och analyserats utifrån främst avkastning och risk. I studien avser riskjusterad överavkastning sådan avkastning för portföljen som överstiger vad som kan förväntas enligt CAPM. Parvisa t-test har genomförts för att avgöra resultatens statistiska signifikans. Bolagen som ingår i studien har varit sådana noterade på Stockholmsbörsens Large Cap mellan 2010-06-30, till och med 2020-06-30.    Slutsats Samtliga portföljer genererade en riskjusterad överavkastning och, med utdelningar inkluderade, en sharpekvot som översteg ett. Strategin baserad på P/B-talet genererade högre riskjusterad överavkastning än strategin baserad på P/E-talet. / Background The fundamental aspect in value investing is to buy assets for a lower market price, than its fundamental value. Over the years a lot of investors have tried to create strategies in order to identify undervalued companies. Particularly popular is value investing strategies based on buying stocks with low P/E and P/B ratios. These strategies have, according to several studies, managed to gain risk adjusted excess returns during the 1980s and 1990s. But during the 2000s, studies have shown inferior results on the American market. On the Swedish market, studies have shown that excess return was possible during the period 1980-2010, but it is still unanswered how the strategy would have performed during the period 2010-2020.    Purpose The purpose is to analyze to what extent a value investing strategy, based on the P/E and P/B ratio, respectively, generates risk adjusted excess return.  Methodology The study is based on a quantitative strategy with a deductive approach. Through a timeseries analysis, portfolios have been created in order to analyze return and risk. Risk adjusted excess returns is in this study, is defined as all returns who exceeds expected return from the CAPM model. Paired T-test have been used to determine the results statistical significance. The assets included in the sample is companies listed on Stockholm Large Cap index between 2010-06-30 and 2020-06-30.    Conclusions All constructed portfolios gained risk adjusted excess return during the period and, with dividends included, a Sharpe ratio higher than one. The strategy based on the P/B ratio outperformed the strategy based on the P/E ratio.
