Force the price of stock or commodity that is heavily sold “short” up in price.......
This price increase forces those who hold the “short” positions to buy the stock back as it rises to cover their short calls.....
The people who drove the stock price up, get a huge profit from the traditional “buy stock low and sell when it’s high”.....
The people with the short position lose...... and badly...
Leveraged short selling could disappear. The hobbits have hacked the system.
