Not really. I mean, a proper correction is definitely overdue, but we're about to go through 2-3 years of excellent economic growth, which in turn should be very positive for earnings. What we should/will see is P/E ratios fall back to their long-term trend, which will be most painful for some speculative/growth stocks, but hardly disastrous.
If you're a long-term investor who has no plans to sell, you should be praying every night for a big correction of some kind - a perfect opportunity to get great companies/assets at a discount.
