I short AMZN too because it is the most over overvalued stock. Its growth story near end. Its revenue growth ration year/year will be less than 20% in the current quarter. Profit growth is negative. Its stock performance will be similar to CSCO when it's $65. Basically will keep going down when it has smaller and smaller growth. Most likely next year its growth will be single digital year over year due to big sales tax impact and serious competition from local retails.
You must be aware that for every new share shorted, an additional long share is "created".
For each short share, two people will show a long position in their account for that share; the person from whom the share was borrowed (to lend to the short seller) and the person who bought the share from the short seller.
Therefore, two people think they own that share, and each brokerage account will reflect that they own the share.
Therefore, for each shorted share, there are two potential share owners (who could decide to sell).
Therefore a squeeze is just as likely to occur in either direction, depending on who has the upper hand that day.
