A company which survives all the negative forces thrives in the future. A company or a startup generally focus on solving problem. The bigger the problem, the bigger the opportunity, and sometimes the bigger the risk. But taking such rewards yields better results. Results really defines the success. So whenever a company makes good amount of return as per their vision or greater than the previous year. And more probably we can see that those organization which survive the dip offers a very good incentives to investors as the future.
During the dotcom bubble that happened in the late 20th century, those ventures which survived yielded a very good return to the investors later. Only a fundamentally strong company could survive such kind of dip. After that people are convinced about it bright future and those who then became the retail investors made a try.
Therefore a dip or even a horrible dip has such kind of advantages. It can convince people and investors to trust.
