$Sandisk(SNDK.US) There are many retail investors in the SanDisk market. Some are persistently bullish, targeting 700+; some take profits at 650; some start shorting at 650; and there are also small retail investors who shout about a crash at the support level every day. In reality, there aren't many retail investors who consistently profit from shorting all the time because the momentum of the trend hasn't run its course yet. Even in a volatile market, short sellers can be shaken out. I can't say SanDisk will keep rising forever, but on a day when SanDisk crashes, you won't be able to capture the entire drop before having to take profits if you're shorting. So, either take profits on your short position and wait for the adjustment to complete, or wait for the top to form.
