It is typical of this stock market. That is why you take profits before they pull the rug out, or use a conditional sell to take profits on a big run like this one had. I think CYTR is the one to own this week. My mistake was not buying RXII 2-3 months ago after the huge pull back when CYTR sold the last batch of shares slowly to retailers and ran the price down last time to under $2. This time they a smarter deal, but diluted RXII this time, but did not dilute with an interesting twist where RXII buys their own shares, sets the price, then sells accreditied investors more shares to raise the cash, plus extra cash. Brilliant.
