Hooter,

HDR is ex-entitlement tomorrow, 6th April, so Yes, today is the last cum-entitlement day.
If the stock closes at the current price, $1.45, tomorrow the stock should trade at $1.40, the theoretical ex-ent price.
This will have an effect on the warrants, but how muc is your guess. I'm staying away from the warrants, through bitter past experience.

Once the stock is ex-ent I'd envisage the price drifting a little. The maths are too good. Sell at 1.40, say, to buy the new stock at 1.10.
