All time low is 3.59 in 2003. Go to Etrade then get a quote for BRCD, then choose "Performance Summary" (you do not have to have an account to do this) it shows that BRCD goes down to around $4 each year, then climbs back up close to $8. Then drops down to 4 and climbs back to 8. so what does that tell you? This is very likely the bottom, unless there is more too the earnings restatement than just stock options. It's possible it will drop to 3.50 range, but it looks like 3.90 is the bottom for now and could be the bottom for this year.
Here is link to Etrade, but I do not think it will show the BRCD info unless you type it in the quote box and choose "performance summary"
