mark luschini joins us now as well as jack abalon. mark, let me start with you. do we need a pullback nor the market really t be healthy? >> i don't think we need a pullback, tyler, at least not in that vein. certainly like many i would welcome one, i think it would reenergize equity investorers. there's no law that says we have to find one. over the last 34 years, there has been a correction of that order 19 times. it hasn't been 100%, as a consequence, i think as long awe continue to see the economic and corporate fundamentals improving, that should allow for stock prices to advance commence rat with earnings growth. i don't think we need to have one in order to invite continued interest in equities. >> you are of a different opinion. you think we do need a correction in the stock market. tell us why? >> sure, i think that there are a lot of investors sitting on the sidelines, because valuations are expensive. i think mark is right, as long as earnings can outpace current valuations for a while and revenues can outpace them perhaps we could move forward without
