NorthWest Biotherapeutics Inc (NWBO)

As we know the company controls whether or not it's warrants can be shorted. If NWBO allowed shorting across all it's warrants over the years then they are giving permission to all investors with warrants to play games with the share price and basically short the stock. In other words NWBO are simply not interested in allowing the pps to rise and may use this to benefit themselves immensely and at the same time cause a great deal of pain on long term retailers.
As we all know in the shorting game the warrants can be used as insurance to those investors shorting a stock and if these games have been played then you can be sure that there has been a coordinated effort to drive the share price down and if and when the pps reverses significantly these same investors can use these warrants to cover their short position.
