Do not Do Mutual funds ever. b/c fees at 200+ basis points generally.
Index funds are what you're looking for, because fees between 18 and 25 basis points usually.
Paying people to lose money for you is never fun.
market is being propped by funny money right now many people saying crash immanent. No one knows when it will hit but many many people are watching. and sharks have been waiting patiently for blood to spill.
It would make sense in my head that if you're going with the completely passive option to
80% Positive index. 20% inverse index possibly leveraged.
As always I suggest learning to trade options instead.

The market as of last week just lost 100% of the gains this year. if you want to go completely passive that's your choice. but 100% risk for 0 gains gives me the heebie jeebies worse than doing lending club or prosper.
Any way going in without a plan and exit strategy is like asking for the universe to kick you straight in the ass.
The main reason people invest passively in the market is that despite fluctuations it generally rises year after year. that's why their time horizons are so large.
Your time horizon is small. passive investing will probably get you around 150-1500 if you're lucky. More than likely you're gonna lose that.
