Can you name a time when the markets weren't "uncertain" and everything was perfectly stable? In my 65 years on the planet, I cannot remember one. I like to read history, and I've yet to read about such a time before my birth.
With any available cash, I am always on the hunt for long-term bargains. That is, I want to buy something that I think will be worth a lot more in the distant future, and I want some insurance, or a margin for error, by buying it when its current price is depressed. When the market is near an all-time high, like it is now, such bargains are very hard to find.
I normally hold 100% equities, but at the moment, I'm sitting on more cash than I usually do---about 1.5% of my total portfolio. When the bargains eventually reappear (they always do), I'll deploy all but two or three months' worth of expenses into equities.
