How does one keep up with coins gaining or about to gain?

Just now, I see that amdst the brutal slip down hills, coins like ZEC and ZEN are on the rise. ZEC went from 20 USD to 400 USD+...

And analysis state that coin surged due to "significant developments and renewed investor interest".

Are these parameter measurable? Is there a way to keep an eye out for such gains in the pool of almost infinite coins?
