I respect both of your opinions. Obviously TSRX is the better stock in the long run. However, consider that DRTX is about to file their NDA and their market cap is so low, it would take very little to move this stock tremendously. I think DRTX in the short term (1) month will outpace TSRX, however TSXR will beat it in the long run. Keep in mind that this company is owned by a group of investors who's only objective is to sell the company. Thus I think it's more likely that these investors are willing to sell the company for less and quicker than TSRX, meaning that there might be a significant gain in the near term.
