Where do you all store your money / handle non real estate investments?

[Joshua Sun]

Before I got into real estate investing, I would put my a big chunk of my saved money into into an S&P 500 index fund and work 401K. 

I now find myself putting less and less into index funds, stocks, and 401K, and easing more into a general bank savings account. I find it to be less fluctuating since the goal is to put that money right back into real estate. This is all separate from an emergency fund. 

Curious how all of you approach storage for savings. 

Thanks!
