To a stock broker with an inexperienced customer, there is a world of difference between an over-the-counter oil-in-Israel penny stock and a NASDAQ traded oil-in-Israel penny stock. Some brokers won't even handle the former, buy or sell, for anyone, no matter how experienced they are.
In addition, once dropped from the NASDAQ, it's unlikely they will ever rejoin. The requirements for joining the NASDAQ is higher then the level for being dumped.
But I guess it all depends on your expectations for Zion Oil. If you so desire, "It doesn't matter" can be defended on several levels. It is, after, Zion Oil.
