That's what I'm thinking.
$5,000 invested at $12 a share , jump up to $70-80 a share and your into some coin. Sure you may loose it all but I very much doubt it.
It would have to be a sell as soon as it spiked kinda deal.
RIM is trading below book value and at liquidation levels. You aren't at risk of losing it all as RIM is trading at the value of their physical assets. Indicators will tell you that the stock is way oversold. RIM's multiples are at incredible levels and its difficult to see the stock go much lower this year. They have over a billion bucks in the bank, are still highly profitable, have 75+ million subscribers etc... and are expanding internationally.
On the flip side, be aware that RIM's stock has been and is still being heavily shorted. There is tremendous pressure weighing this stock down and the media/analyst beat up on RIM daily which is only adding fuel to the fire. So, while in theory RIM shouldn't really drop much more, you never know with the way the markets are. Sentiment on RIM is so incredibly negative as many investors are justifiably frustrated to the point that they have probably just thrown in the towel. RIM's expansion is into areas where there is less profit margin so it hasn't done much to help the fact that they are declining in market share in North America. RIM has been just way to slow in responding to changes in the marketplace and I dont know if they've fixed that issue. They have been plagued with delays and it seems like the answer to this issue is that they no longer declare deadlines.. They say the new BB10 will be available later this year rather than giving a more detailed timeline.
I think a lot of people have taken a "wait and see" stance on RIM as they want more proof they will succeed rather than speculate that they might succeed again. I would absolutely not call RIM an "investment". Its really a gamble at this point. RIM is also going to be releasing quarterly earnings numbers later this month and it could be bad or it could pleasantly surprise. Analyst seem to think its going to be bad but who knows.
I also would not count on a buyout any more. You never know but it seems like RIM doesn't want to be bought out as they put the wheels in motion and think they can dig themselves out of the hole they put themselves in. Also, I think every potential suitor has gone a different direction. Microsoft I think was the best bet but they passed on RIM and are going with Windows phone 8. I don't think a hostile takeover by a private equity firm could happen either because the Canadian Govt might decide to block it. If RIM fails miserably with BB10, perhaps a buyout could occur then by somebody who wants to scoop up the pieces but it would not be at a great premium.
I also think your expectations of 70-80 is way too high. I know most would just like to see this stock in the $20's where it probably should be right now. Even if they return to glory, its a different game right now and they will not regain the dominance they once had as Apple and Android are here to stay.
Optimistically, buying RIM stock at these levels, you could hope for a double or triple but you never know. Its worth a play though but then again there are many stocks out there that are worth a play.
