Thanks, UCAZZ012.
First, I am a trader and not a long term investor. This means I do not fall in love with a company (nor fall for their pie-in-the-sky BS).
Second, as to AMBS, it is a real company with unproven possibilities. The company does have a toxic financier in place who seems to care about PPS. This tells me until a real breakthrough, AMBS will play the balancing game of short term cash-need vs long-term prospects.
Bottom line FOR ME, I look for a trading range where it makes sense for my risk tolerance.
Notice I stated "FOR ME" and not anyone else. YOU can only blame yourself when playing with fire (penny stocks). AND YES, I have been burnt many times even with the best of DDs.
Good luck and remember not to be greedy. The hardest part of investing is not "when to buy" but "when to sell."
