The fact that EXAD lost 90% of its value only means that this stock has to be held long. Besides, there is nothing wrong with holding EXAD. After all, holding EXAD LONG was the recommendation even before the SEC suspension, so just stick to the plan and hold till this recovers and reaches "pennyland".
The SEC did not suspend EXAD for being a pump and dump. The SEC suspended trading for noncompliance related to the filings. If EXAD is indeed a legitimate company, then there is nothing to worry about, I assume.
It may take a few years to recover, but if I remember that was the plan, right? No more short term taxes. Hold long and avoid taxes, LOL.
99% of penny stocks are pump and dumps, yet 100% of penny stocks pretend to be in the 1%. Contracts, patents, mergers, partnerships, and other such news are usually "too good to be true" and should be looked at in detail. The source should also be vetted.
