The selloff was on weak volume, so my guess would be that the last selloff was individual investors taking their winnings in a really bad week for the nasdaq. As for a warning, I doubt it. My first thought is that the company is quite young, with no established pattern of announcing/not announcing. Secondly, all indications are that the market meltdown hasnt affected the building sector. On the contrary, the energy building/surveying markets continue to do well. If the market recovers, this industry will have escaped unscathed. Cant think of many others that have been this fortunate.
