Rambus shares have broken some key supports in the $18 to $16 range. In other words, the long-term trend has turned negative. My target will be the $13.11-13.25 range. Please note there is some support near $14 and I expect a bounce there but the prevailing pattern is bearish. Fresh exposures may be avoided.
There are conflicting recommendation among various sites. As an example optionmonster describe a bearish trend but then there are others describing bullish trend.
Best bet is to protect with puts and let the market tell us what we need to do. For a new position IMO buying calls offers a limited risk.
