Onconova Therapeutics Inc Warrants (ONTXW)

[Dollar Bill]

ONTXW is a warrant. What that means is if you buy the warrant you have a option to purchase the stock ONTX at a particular price before the warrant expires. Once the warrant has expired it is worthless. So you must either sell the warrant ONTXW on the open market as if it were a stock or exercise the warrant meaning you purchase shares of ONTX at the designated price and then you can keep or sell them. Basically warrants are like options.
clear as mud eh?
