Earnings is on Jan 25. Manipulators might use it as an opportunity to drive price down by 50c or so, and you may be able to time your buy. Of course, current pps may also have gone up by $1 or so by then.
Just looked at the chart. Nice march since first of year. I guess it will keep it up to late Feb when the FDA must issue an answer. My fear is that when they do approve TDM-1 there will be stagnation or even a drop because all the speculation will have been removed. It happens to stocks all the time. Then it takes another year to get it moving again -- until they release the earnings on the new product. I really believe in these guys. I have been tracking it for years -- since I lost my wife to Merkel Cell -- I really believe they are onto something that works, and I sure hope they get the first one released very soon -- to help those that need it -- and we should benefit, too.
Just go to their website for the pipeline of wholly owned and partnered products, and read all bullish and bearish blogs and news in yahoo finance. Technology is tops, but you need to have the patience to hold this for at least 1.5 more years, since this is highly manipulated like a lot of biotech stocks, but a buy at today's pps will be richly rewarded.
