Hi guys...is anyone here familiar with high-risk, short-term investments in companies like Winmark Corp (winmarknotes.com) and Sten Corp (stennotes.com), as well as Oxford Capital Partners (ocplimited.co.uk)? I can't really find anything online...basically the high interest rates look appealing, but the investments aren't insured and to be honest I don't really understand how they work. I'm currently in college (it's all paid for on a full scholarship) making $1000-2000 per month at a job. I've been looking around lately for good CD deals and putting $1000 here and there, etc., generally 3-4% interest. Are these higher-risk/yield securities worth looking into or is it well-known that people can often lose their money in these things?
