Unless it's in cash, it's "tied up". That's the definition of an investment, either short term or long term.

So what? Given the trivial transaction costs involved with converting stock in publicly-traded companies to cash - you probably won't even have to pay a commission - it's still worth almost exactly the same as cash at any given time.

Whatever (minor) reduction in value comes with the trivial loss of liquidity of being in easily converted marketable securities does not reduce the value of the assets to zero. Or even much at all.
