Warrants (Canada & USA)

[calgarylady]

Actually if you use the volatility rate posted there and go here and use the calculator you can get an idea of what the warrants are worth during the week when they are trading. Here are a couple of sites with free calculator and use 5% as the interest rate and no dividend. If there is news then the volatility rate can rise substantially making the value of the warrant go up very fast so keep that in mind if the stock is running.

Peter Hoadley's is probably the best but you only get 10 or 20 calculations an hour free but usually that is lots.

Hope this helps.
