The final judgment is certainly up to you. There are a number of factors you have to consider, for example if this is in a retirement account then you are not considering a quick turnover. If you think the housing market is going to tank and you will need cash in 8 months to buy a new house, then any speculative venture is risky, and you are better off to buy gold or silver in this market. If you have a year or two time frame, then right now it has been calculated that SLI, just with the known metals is worth $3-3.50 per share. Since it is in a protective sector, considering the chance of a world-wide bust in the next year or so, then in my opinion if this is speculative money then it is probably safer and has a much greater chance of success than anything else that I can think of.

Also you are should not have a stop loss and just occasionally look at the share price once you have filled to your comfort level.
