WPI chart, page-41

This may be a little off topic but has anybody had experience in the shell scene when things turn ugly in the general global markets?
I understand for example LinkedIn (tumbling 40+% yesterday) being deemed overvalued based on weaker than expected results.. But does weakness in technology stocks flow on over here in our somewhat maturing RTO tech scene?
I'm thinking that because the company value is minimal at WPI for example that we are only possibly likely to see a softening of the hype factor putting a little pressure on the SP spikes.. but gains are surely still to be made in the undervalued shells in our own back yard..
I've only been trading/investing around 13 months so would love a heads up on what it's like when the Bull turns Bear..
