Equity issue announcement vs. the stock price : An event study of how an announcement of an upcoming equity issue affects the stock price (English)
Abstract [sv]

Marknadens reaktion när ett företag informerar och annonserar om en eventuell nyemission sägs vara oförutsägbar. Enligt tidigare forskning pressas aktiekursen i de flesta fallen nedåt vid en nyemission. Under det senaste året har en del nyemissioner utförts i synnerhet på grund av den globala lågkonjunkturen då många företag haft för lite kapitalbas. Vad gäller företag på Stockholmsbörsen som valt att nyemittera aktier har även här de flesta fått se sin aktiekurs rasa.

Författarna till denna uppsats avser att studera hur marknaden reagerar på ett offentligt tillkännagivande av en kommande nyemission. Det undersöks även om det förefaller någon skillnad mellan tillkännagivanden av nyemissioner genomförda innan eller under lågkonjunkturen och skillnader branscher emellan.

Då vi ville se hur denna händelse påverkar ett företags aktiekurser valde vi att göra en eventstudie. En eventstudie ger oss möjligheten att mäta effekten av en specifik händelse. Datainsamlingen har endast bestått av sekundärdata som vetenskapliga artiklar, litteratur, tidigare forskning samt elektroniska databaser så som Avanza och OMX. Vi valde att ta med alla de företag som under tidsperioden 2005-01-01 till 2009-04-01 annonserat om en nyemission och som i dagsläget fortfarande är noterade på OMX, Stockholmsbörsen.

I studien ingick 21 tillkännagivanden varav hela 13 stycken, ca 62 % av dem, resulterade i en negativ kursreaktion och avkastning. Fyra av åtta tillkännagivanden om nyemission som offentliggjordes innan lågkonjunkturen uppvisade en nedåtgående kursreaktion på annonseringsdagen och därmed en negativ abnormal avkastning. Denna trend fortsätter att hålla i sig då även nio av 13 tillkännagivanden under lågkonjunkturen, visade på en negativ abnormal avkastning.

 

 

 

Abstract [en]

The market reaction when a company provides information about a possible equity issue is said to be unpredictable. According to previous research the stock price, in most cases, is pushed downward in case of an equity issue. Over the past year some equity issues has been implemented particular because of the global recession. This because many companies experience too small funds. As for companies on the Stockholm Stock Exchange that have chosen to do an equity issue most of them had also experienced a decline in the stock price.

The authors of this essay intend to study how the market reacts to a public announcement of an upcoming equity issue. They would also like to know if there is any differences between the announcements of an equity issue that's been done before or during the recession and if there is any differences between industries.

Thus we wanted to see how equity issues affect a company's stock price, we have chosen to do an event study. An event study enables us to measure the effect of a specific event. The data that we been using has only consisted of secondary data as scientific articles, literature, previous research and electronic databases such as Avanza and OMX. For our study we have chosen to include all of the companies that during the period 2005-01-01 to 2009-04-01 announced about an upcoming equity issue and are still listed at the OMX, on the Stockholm Stock Exchange.

The study included 21 public notices of which entirely 13 of them, about 62 %, resulted in a negative rate reaction and return. Four of the eight notices about an equity issue, which was announced before the recession, resulted in a declining rate reaction on the day of the announcement and also had a negative abnormal return. This trend continues thus nine of 13 notices, which announced an equity issue during the recession, also showed a negative abnormal return.
