text: what is the beta of a small 3mm software and services company? beta is the mesure of volitility and used in finantial calculations. if this company is public and its stock is traded on a stock exchange, you can find its beta (vs. s&p500) on yahoo! finance or other financial web sites.  if you are interested in its beta compared to some other indices, you will need to compare the stock's price movement over a long period of time to the specific index concerned.  most finance/investment text book will teach that calculation.    if this stock is not public, i don't think you can find a beta as it has no price history for the analysis.  or you can pick another software company of similar size that is public and use its beta as a comparable.  hope this helps.  good luck.
