I am not a guru, but in last weeks I saw positive activity in RAD:
- they refinanced debt - a major thing for company with so much debt
- to everybody's surprise, they acquired a small private network (stock went down on that news - but it's questionnable)
- many analysts have now positive vew on RAD despite Debt/Value ratio, including ZACS (strong Buy), SCHWAB (letter B which corresponds to BUY) etc.
Therefore, I am not surprised to see this uptrend today to the recent highs. Do not forget: RAD is a buyback candidate (although far from the perfect one).
