                            <p>Investigating andevaluating these research costs (R&amp;amp;D) investments in stock returns andstock price volatility are examined. The contribution of the R&amp;amp;Dinvestments of the sector to the country&#039;s economy and the concentration ofR&amp;amp;D investments are taken into consideration. The firms that are active inthe information sector are investigating the relationship between R&amp;amp;Dinvestments and stock returns and price volatility. In this context, the relationship between R&amp;amp;Dinvestments of 14 firms operating in the BIST technology sector between2011-2015 and stock returns and stock volatility has been analyzed by panelregression method. Two models wereestablished in the scope of the study. In the first model, the effects of R&amp;amp;Dinvestments and R&amp;amp;D intensity on stock returns were examined. In the secondmodel, the effects of R&amp;amp;D investments and R&amp;amp;D intensity on pricevolatility were examined. According to the results, there is a positiverelationship between R&amp;amp;D investments and stocks, while there is no significantrelationship between R&amp;amp;D intensity and stocks. While there is a negativeand meaningful relationship between stock price volatility and R&amp;amp;Dinvestments, no significant relationship between R&amp;amp;D intensity and stockprice volatility has been found.</p></trans-abstract>

Bu kapsamda 2011-2015 yılları arasında BIST teknolojisektöründe faaliyet gösteren 14 firmanın Ar-Ge yatırımları ile pay senedigetirileri ve pay senedi volatilitesi arasındaki ilişki panel regresyon yöntemiile analiz edilmiştir. Çalışma kapsamında iki model kurulmuştur. İlk modeldeAr-Ge yatırımları ve Ar-Ge yoğunluğunun pay senedi getirilerine etkisiincelenirken, ikinci modelde ise Ar-Ge yatırımları ve Ar-Ge yoğunluğunun fiyat volatilitesineetkisi incelenmiştir. Elde edilen sonuçlara göre Ar-Ge yatırımları ile paysenedi getirileri arasında pozitif bir ilişki saptanırken, Ar-Ge yoğunluğu ile paysenedi getirileri arasında anlamlı bir ilişkiye rastlanmamıştır. Pay senedifiyat volatilitesi ile Ar-Ge yatırımları arasında ise negatif ve anlamlı birilişkiye rastlanırken, Ar-Ge yoğunluğu ile pay senedi fiyat volatilitesiarasında anlamlı bir ilişki tespit edilememiştir.</p></abstract>
