Where did you pull that definition of 'dot.com' from? Out of the 'air'?
How can anyone trade without knowing anything about trading history or even the terminology?
DotCom DEFINITION: A company whose operations are entirely or primarily internet-based, or more specifically a company whose business model would not be possible if the internet did not exist. Dotcoms often deliver all their services over an internet interface, but products might be delivered through traditional channels as well. Dotcoms are often divided into two categories: those that provide products and services for consumers (B2C) and those that provide products and services to other businesses (B2B).
IN 1999, Yahoo, Ebay, Amazon, AOL were known as the big dot-coms, and they LED the dot com bubble.
THEIR FALL marked the dotcom bubble bursting. Ie., in 2000, YHOO was $125. At its low, in 2001 after the fall, YHOO was $5. $125 to $5 is quite a burst. All the dotcoms did that. Today, 7 years later, YHOO is $31.
The point I made was, many of them failed, a handful of them succeeded.
I would say that the dot-coms Google, Amzn, Ebay, Yahoo among others, have succeeded quite well. Further, in 1999, some had positive cash flow... their growth rate is what caused the dotcom bubble. THEIR success is what led people to speculate on the less legitimate dot.coms that ultimately went bust. As you can see, they are still successful.
How can I compare?
It's a very very close analogy. In 1997, the above companies were in their infancy also. 10 years later, they are established as part of the economy and society.
Solar is here to stay, but not every solar or alternate energy company will be equally successful. It's still not clear which will be the google ($450+), which will be the ebay ($30+), which will be the learntogo ($0) .
You're welcome.
