CNBC.com featured a commentary entitled, "What investors need to know about going to cash during stock market corrections." Guest Contributor Mitch Goldberg of ClientFirst Strategy writes, "Say hello to investors' new best friend -- cash. It is an old friend, as well. Cash is an important part of any investor's portfolio, but how much you should allocate to it depends on a number of factors, and not all of them have to do with how old you are." The piece explains, "Now that money market funds are yielding 2 percent, the 'cash drag' from the days when interest rates were pegged at zero are gone. In fact, a money market position yielding 2 percent may prove to be your biggest winner for 2018." It add, "As a financial advisor who likes to assort my clients' accounts based on time horizons and the timing of cash needs -- as opposed to the old way of just based on client age or account value -- I can tell you that cash and cash equivalents play a critical role in portfolio composition.... The bottom line is that there is no single one-size-fits-all way to allocate to cash."
