Sellers usually prefer to allocate as much as possible to capital gain assets and intangibles rather than ordinary income assets, whereas buyers typically want to allocate to assets they can depreciate rapidly. Therefore, the allocation is often a negotiated component of a sales agreement.
Many financial advisors recommend a 60/40 asset allocation between stocks and fixed income to take advantage of growth while keeping up your defenses. Here's how 60/40 is supposed to work: In a good year on Wall Street, the 60% of your portfolio in stocks provides strong growth.
A common rule of thumb is 100 minus your age to determine your allocation to stocks. For example, if you are 30, then you'd allocate 70% to stocks and 30% to bonds (100 - 30 = 70). If you are 60, you'd allocate 40% to stocks and 60% to bonds (100 - 60 = 40).
