We are smart but you are the "smartest"....I mean who would not want to ride a stock from 240 to 170 and back.....who does not like roller coaster. Don't tell me there are stupids out there who sold at 240 and got back in at 170 again.
Buyers are not idiots. They just know when to buy. Hopefully they will know when to get out. The art of shorting gets down to knowing when to put in your initial position. Right now the pe is high. But with the level of sales they are achieving (and growing each quarter) any change in operations that could alter the margins just a couple percent could result in hundreds of millions in profits and could amount to dollars in earnings rather than pennies. That could change the pe from 3900 to 100 in just a qtr or two. With this stock growing sales the time to go short will be when you see the sales growth slowing down. Now is not the time but it is getting closer now. Much closer. Listen to the earnings call and have patience.
