One of the great advancements in the investment field in recent years has been the adaptation of the power of the home computer to the task of doing technical analysis of various types of investments. In previous decades, personal computers were simply not powerful enough — the processors were not capable of that kind of complex mathematical calculation, and those computers could not store very much data — hard drives were much smaller in storage capacity, and most computers did not have very much RAM memory installed in them. But today’s generation of computers have huge hard drives and very powerful CPUs, and some really wonderful desktop analysis software is now available, allowing the average investor to do high-level numbercrunching that used to be reserved only for professional investment firms.
