Weekend reading: Rebalancing works

Good reads from around the Web.

One of the hardest things to explain to a new investor is the benefit of rebalancing [1] asset allocations.

Until you’ve had the “aha!” moment, it can seem like madness to reduce your holdings of investments that are doing well, to buy stuff that’s losing you money.

And then, once you’ve had the “aha!” moment – well, then it’s hard to remember what it was like before you “aha!”-ed, making anyone who doesn’t yet get rebalancing seem a bit like a child who doesn’t yet get why they need to eat.

Enter Larry Swedroe, and his short article [2] that proves again how the magic of rebalancing works. Swedroe cites numbers from an author I’ve never heard of, Jaques Lussier, and his book Successful Investing is a Process [3]. Here’s rebalancing in action (US data, but it’s the same principle in the UK):

An investor begins in 1973 with a portfolio that is 50 percent stocks and 50 percent bonds. For the period ending in 2010, stocks outperformed bonds as they returned 9.8 percent versus 7.7 percent for bonds.

If the portfolio was never rebalanced, the ending portfolio would have had an allocation of 68 percent stocks and the annualized (compound) return would have been 8.9 percent.

Knowing that stocks beat bonds by 2.1 percent a year was the investor who never rebalanced better off?

My own experience tells me that most people would assume you would have been better off not rebalancing due to the much higher return of stocks. Yet, a rebalanced portfolio would have returned 9.5 percent, and done so with less volatility.

In other words, the diversification benefit was sufficient to overcome the 2.1 percent disadvantage in returns. During this period the annual correlation of stocks to bonds was close to zero (0.1).

Rebalancing feels bad in the short-term, but it works over the long-term.

Aha!
