Theres no logic to that statement. It will not pull back to 90 cents. Everyone is an expert in a trend, no one is an expert in a trend change. Just because it's dropped today as the DOW dropped significantly does not indicate a downward long term trend for Sirius.
I'd be surprised if it went back under $1.00 given how much the underlying fundamentals have been improving. IMHO, the only thing that could change this trend is if something significant changed with SIRI, like a solar flare or gamma ray burst from an exploding star that puts all their satellites out of commission all at once, or something like that....but the odds are against it.
