Likviditetsstrategi på Stockholmsbörsen : En studie om likviditetspremiens existens och dess eventuella överavkastning

Svartholm, Per, Uhrberg, Magnus January 2012 (has links)
Bakgrund: Det har tidigare konstaterats att det existerar ett samband mellan aktiers likviditet och dess avkastning. Bevis för detta har främst gått att finna på utländska aktiemarknader. På den svenska aktiemarknaden har tidigare utförda studier konstaterat att detta samband inte existerar. Vi vill därför göra en studie på den svenska aktiemarknaden, vilken delvis innefattar en ny tidsperiod för att se om någon likviditetspremie existerar. Syfte: Vårt syfte med denna studie var att undersöka om det är möjligt att uppnå en högre avkastning genom att investera i en portfölj med relativt sett illikvida aktier jämfört med en portfölj bestående av likvida aktier på Stockholmsbörsen samt undersöka om faktorerna likviditet, betavärde samt företagsstorlek signifikant påverkar portföljernas eventuella överavkastning jämfört mot ett lämpligt index. Metod: Vi har skapat tre olika portföljer, med tio aktier i varje vilka representerar de minst, mitterst och mest likvida aktierna enligt vårt valda likviditetsmått, aktieomsättningshastighet. Likviditetsmåttet laggar en månad för att kunna användas som investeringsstrategi. Vi har studerat portföljernas värdeutveckling under perioden september 2003 till december 2011 för att se om portföljernas olika likviditet påverkar avkastningen. Genom regressionsanalyser där aktieomsättningshastighet, betavärde samt storleken använts som oberoende variabler har vi försökt förklara portföljernas överavkastning mot AFGX. Resultat: Vi har kommit fram till att det inte existerar någon likviditetspremie på Stockholmsbörsen under vår valda undersökningsperiod. Det samma gäller under uppåt- respektive nedåtgående marknadstrend. Det enda fallet där en mer illikvid portfölj presterar bäst är under januari månad. / Background: Earlier studies have concluded that there is a connection between a stock’s liquidity and its yield. Proof of this connection has mainly been found on foreign stock exchanges. On the Swedish stock market, earlier studies have concluded that this connection may not exist. The authors therefore intend to do a liquidity study on the Swedish stock market on a partly new time period to see whether this liquidity premium exists or not. Aim: The aim with this study is to investigate if there is a possibility to achieve a higher yield by investing in a portfolio consisting of relatively illiquid stocks contrary a portfolio with highly liquid stocks. We also want to investigate if the factors: liquidity, beta value and company size have a significant impact on the portfolios possible excess return in relation to an appropriate index. Completion: In this study, the authors have constructed three different portfolios consisting of ten stocks, each which represent the least, middle, and highest liquid stocks according to our liquidity measure. This measure has a one-month lag to make it possible to use as an active investment strategy. The authors have studied the portfolios growth during the period September 2003 to December 2011 to investigate if the difference in liquidity has any impact on the return. Through regression analysis, where stock turnover ratio, beta value and company size has been used as independent variables, the study tries to explain the portfolios excess return over the AFGX index. Results: The study concludes that there is no significant liquidity premium during our chosen time period. The same conclusion is drawn on the sub-periods with both an up going and down going market trend. The only period during which an illiquid portfolio outperforms a liquid portfolio is during the month of January.

高研發企業主動揭露預測性非盈餘及智慧資本資訊行為之研究

崔琇玫 Unknown Date (has links)
本研究以1997至2001年國內高研發密度之上市上櫃公司為研究對象,探討高研發密度公司揭露非盈餘以及智慧資本相關資訊之行為。首先探討企業揭露資訊之偏好及趨勢,再分析影響企業揭露非盈餘及智慧資本資訊頻率之因素,並探討企業股價與帳面價值間之差異及股票週轉率與企業揭露智慧資本相關資訊之關聯性。 實證結果發現,公司主動揭露與盈餘有關資訊之頻率有逐年下滑的現象,而揭露非盈餘及智慧資本相關資訊的頻率則有逐漸升高的趨勢。以分組檢定結果而言,未預期盈餘為正且幅度較大的公司在揭露智慧資本資訊方面顯著較未預期盈餘為負且幅度較大的公司積極。就影響企業揭露非盈餘以及智慧資本相關資訊之因素而言,未預期盈餘、員工每人營業利益、研發密集度,以及每人配備率與揭露非盈餘及智慧資本相關資訊之次數均呈顯著正向關係,而董監事持股比率以及用人費用率則與兩項資訊之揭露次數呈顯著負相關。 此外,屬於資訊電子業以及規模較大的公司,揭露非盈餘及智慧資本相關資訊之意願較強。就企業股價與帳面價值之差異以及股票流動性而言,資訊電子業之股價淨值比及股票週轉率均較非資訊電子業為高,策略聯盟(流程資本)資訊揭露次數與股價淨值比呈顯著正(負)向關係,新產品及策略聯盟(人力資本)資訊揭露次數則與股票週轉率呈顯著正(負)相關。 關鍵字:自願性揭露、智慧資本、市價淨值比 / Based on a sample of firm listed on TSE, this thesis investigates the voluntary disclosure behavior ofR&D intensive companies in Taiwan over the period of 1997 to 2001. With an emphasis on non-earnings and intellectual capital-related disclosure policies, we first explore the disclosure behavior in terms of frequency and type of information revealed by management. We then examine whether price-to-book (P/B) ratio and stock turnover ratio reflect the disclosure of non-earnings and intellectual capital-related information. The empirical results suggest a declining trend in disclosing earnings information, with an opposite tendency in non-earnings information over the period examined. In addition, unexpected earnings and variables proxy for intellectual capital determine the disclosure behavior of non-earnings and intellectual capital-related information. Firms with operating performance far beyond market's expectation tend to disclose more intellectual capital-related information than firms with operating performances far worse than market has expected. Variables such as operating income per employee and cost of human resource (proxies for human capital), R&D intensity (proxy for innovation capital), equipment per employee (proxy for process capital) as well as the ratio of directors' shareholding are found to be significantly related to the disclosure frequency of non-earnings and intellectual capital-related information. The findings also indicate that electronics and software industries are more likely to disclose more non-earnings and intellectual capital-related information and have higher price-to-book and stock turnover ratios as compared to other industries in the sample. Firms disclose more (less) strategic alliance (process capital) information is found to have higher price-to-book ratios. Firms disclose more (less) strategic alliance and new product (human capital) information is found to have higher stock turnover ratio. It appears that more disclosure on intellectual capital-related information does not necessarily and monotonously explain the variation in both price-to-book and stock turnover ratios. Key words: voluntary disclosure, intellectual capital, price-to-book ratio, stock turnover ratio

Irrationellt beteende på Stockholmsbörsen : En studie om alfabetiskt bias / Irrational behavior on the Stockholm Stock Exchange : A study about alphabetical bias

Celepli, Rodi, Chaniev, Zelimhan January 2018 (has links)
I allmänhet anges merparten av aktielistor i alfabetisk ordning. Tidigare studier har visat att investerare tenderar att handla aktier som hamnar tidigt i aktielistan mer frekvent än aktie som förekommer sent i aktielistan. Forskning inom psykologi föreslår att individer som möter ett stort antal alternativ försöker hitta genvägar för att underlätta beslutsfattandet. Det leder till irrationellt beteende hos investeraren där den letar efter första acceptabla alternativet istället för att bearbeta all tillgänglig information som berör aktier i aktielistan. Därför när investeraren söker igenom aktielistan i alfabetisk ordning uppifrån och ner har tidigt placerade aktier större chans att bli valda. Vi kommer i denna uppsats undersöka om det finns ”alfabetiskt bias” på Stockholmsbörsen. Studien undersöker om det finns ett samband mellan aktiens placering i aktielistan och aktieomsättningshastighet eller Tobins Q. Vi undersöker också om det finns skillnad i marknadsvärde och namnflyt mellan aktier som förekommer tidigt på aktielistan och aktier som står sent på listan. Resultatet från studien har visat att aktier som kommer tidigt i aktielistan handlas mer frekvent (aktieomsättningshastighet) och erhåller högre Tobins Q än aktier som förekommer senare i aktielistan. Vidare visade vår undersökning att det inte finns skillnad i marknadsvärde eller namnflyt mellan tidigt och sent placerade aktier. Det innebär att det finns belägg för att aktielistor i alfabetisk ordning bidrar till irrationellt beteende hos investerare på Stockholmsbörsen. / In general, stock information is presented in alphabetical order by company name or ticker symbol. Previous studies have shown that investors tend to trade stocks that fall early in the stock list more frequently than stocks that are late in the stock list. Research in psychology suggests that individuals encountering a large number of options try to find shortcuts to facilitate decision making. This leads to irrational behavior, where investor is looking for the first acceptable alternative instead of processing all available information relative to shares in the stock list. Therefore, when the investor searches through stock list from top to bottom, early stocks have a greater chance of being selected. This study will investigate whether there is "alphabetical bias" on the Stockholm Stock Exchange. The study investigates whether there is a correlation between the stock's placement in the stock list and the stock turnover rate or Tobins Q. We also investigate whether there is a difference in market value and name fluency between shares that are listed early on the stock list and stocks that are presented late on the list. The result of the study has shown that stocks placed early in the stock list are traded more frequently (share turnover rate) and receive higher Tobins Q than shares that appear later in the stock list. Furthermore, our survey shows that there is no difference in market value or name fluency between early and late stocks. This means there is evidence that stock lists in alphabetical order contribute to irrational behavior among investors on the Stockholm Stock Exchange.
