No. It means that your stock isn't worth the paper it is written on. However, the company can stay in business (operate in the red), close, or file bankruptcy. You do NOT want them to file bankruptcy!!! When companies do this, bills are paid first (rightly so)...then owners (stock holders). If nothing is left over...you get nothing. You are only out your investment.
The market, as you know, is fluctuating all over right now. So, several things can happen. The stock can continue to dip, it can hover, I seriously doubt it is going to go up. (Even if it was a company that is part of the bail-out).
What should you do? Depends. If the business is not filing bankruptcy or is not announcing that the may be filing & are a part of the bail out...I might hold on. There is a slim long-term possiblity that the company may recover.
Example: GM. There stock was valued at $0 last week, Wednesday it was up to $3 and change. (Part of that is people buying low hoping for a bail-out)
If the company is filing bankruptcy or has announced they may...I'd already dropped it.
Example: GM, again. If the auto industry is not included in the bail-out, GM has stated they will be forced to file bankruptcy. At that pt. , it won't matter how cheap you bought their stock...it is still losing money. Like I said earlier, a bankrupt company often times will not have money left over (after bills (including salaries, day to day operation expenses, and pensions) for the stock holders.
Need to get ahold of whoever is handling your portfolio, ASAP...and find out exactly what is going on with the company.
