First, a word on Twitter (TWTR) . I check my feed every day. I try to answer as many as I can without devoting my day to it. Some people are just being real nice and I favor them. Others are asking exactly what I just answered the night before on "Mad Money" or in Real Money for TheStreet. That's annoying, because we work really hard on both, and 140 words just don't do them justice after we have tried to be very thoughtful about them.
Still others are, frankly, dumbfounding, and I am going to include this questioner because it shows how clueless someone can be about both my work and investing in general.
The first sentence, "what happened to Mobileye," implies something major might have occurred. For heaven's sakes, the stock was down a buck in yesterday's session after doubling in pretty much a straight line. So my answer is: Stocks tend to have people sell them after huge runs, because it's prudent to lock in gains. That's the case with Mobileye's stock. There were more sellers than buyers at higher levels, and the stock had to get knocked down to find more of them.
