The Effect of Behavioral Finance on Stock Investment Decisions

Sample of the Study

The researchers used the random sampling and the study population included all individual investors at Amman Stock Exchange (ASE). 165 questionnaires were distributed among participants in trading halls of ASE, The researchers aimed to make his study distinguished by generalizing its results. So they selected the random sampling approach but when the researchers started to distribute the questionnaires, they found that there was a lack of cooperation from the investors, while observing the trading process at the halls in the Housing Bank Complex. Thus, they selected a more convenient sampling technique although some studies do not recommend this technique which depends on applying a probability sampling technique.

The distributed (165) questionnaires were retrieved, (15) questionnaires had been eliminated to show the research lack of ability to analyze, so the rate of retrieved questionnaires was (83.3%). The researcher thought that one reason for such lower rate was that investors were using new technologies in stock trading on the internet and applying smart analysis for each stock that they already trade in.
