In naked shorting, traders who hope to profit from falling prices sell shares without borrowing stock. Using that strategy, naked short sellers can drive down prices by flooding the market with orders to sell shares they don't have.
If you can't beat them, join them so that you can also benefit. However, short selling is very, very risky and it's not for everybody. If you don't know how to play naked short selling, please move to safer grounds until the tide clears up.
The whole trading market is a broker market. The rise and fall in the market some times since very fast that is because of the brokers playing in the market with huge amount of money. U see the market moving up and down with no proper financial news.
This market moves on agents or huge company brokers. When we say the market is volatile it is because agents of big company put their money to purchase or sell shares of different companies and disturb the market and disturbs the traders and take them towards loss.
