Traders who buy low and sell high, whether they hold the stock for a few minutes, hours, weeks, or years, will always add support as you suggest.

However, it is the shorters that I have a problem with.

There are the individuals that do naked shorts on a stock, making money as the SP falls. Whether the shorter is naked or not, they create a lot of volume, with the naked shorters selling stocks that don't really exist. When the market sees a high volume on a downward tick, then those share holders who are a little nervous put in sell orders, or worse, stop loss orders.

Once the short traders have met their strike price, they put in cover orders, which don't necessarily help to restore the SP, as the stocks for a cover exist in the same dimension as the naked short stocks did.

In the US, naked shorts are illegal.

In Canada, unless you hold the stock certificates in your hands and have permitted them to be borrowed for trading, then you are participating in what is referred to as normal shorting. The bank, or other broker, which holds your shares, lends these to the shorters, without your consent or knowledge. They also make money doing this, by charging interest to the shorter.

In Canada, naked shorts are legal.

If you go to the OT forum on Noront's hub, there is a letter being drafted for interested individuals to send to their parliament members, asking for regulation changes.
