Whilst I was traveling, I hope that you had a little time to reflect on some of the advice that I’ve been dishing out over the last few years?
It’s important that you don’t just follow my (or anybody’s) advice blindly, else you may end up making some fatal logic errors like this poor bloke:
Suppose I have 100K in an index fund that has a ten year return of 7.4%, a five year return of 8.2%, a 3 year return of 17.5%, and a 1 year return of 24.76%. That is a pretty dependable return over the last few years, but it will probably not keep up with the 24.76% return, but will probably maintain at least a 7% return over the next year. So I assume that 7% return.
I want to buy a car for 100K. I can take money out of the index fund to buy the car, and give up $7000 over the next year. I can borrow money at 2% and pay $2000 in interest over the next year. If I choose to pay cash, I lose $7K, but if I borrow and leave my own $100K in the mutual fund, I pay $2K and earn $7K, for a net gain of $5K.
So my logic says that paying cash for anything when the investment return is higher than the interest rate is a mistake. Suze Orman won’t give me advice on this, so if my logic is off, I hope someone will show me better logic.
Have you spotted the flaws?
The principle of taking a 2% loan on the car so that he can invest at 7% elsewhere is sound, BUT his assumptions are wrong:
1. A low-interest car loan is generally subsidized by price.
Check the true rate, if it’s more than 2% then he is probably better off negotiating the cash price lower THEN doing his cash v finance analysis.
2. Unless he’s planning on a 7+ year auto loan, the correct comparison is the finance rate on the loan against a CD for the same term.
This is because the stock market is way too volatile and he needs an investing horizon of at least 7 – 10 years before returns even approach ‘normal’.
In fact, even though this chart doesn’t show that time period, he needs at least 30 years (based on nearly 100 years of data) to ‘guarantee’ at least an 8% return (the worst thirty-year period delivered an average annual rate of 8.5% between 1929 and 1958).
3. Your past returns are NO predictor of future performance:
His ~25% of last year could just as easily be a LOSS of 48% next year. Look what happened in 2008:
But, he redeems himself, somewhat:
The same logic applies to my mortgage: I pay 2.62% on my house. I could pay it off, but taking the money out of an international fund with a one year return of 22.85% would result in a net loss of $100k over the next year (moving $500K from an investment at 22.85% to pay off a $500K balance at 2.62%).
4. On the other hand, his mortgage comparison is ideal:
If you can lock in a 3o year mortgage, fixed at today’s ridiculously low rates, and lock that money into a low-cost index fund for the same period then, yes, you are almost assured of a 3%+ net return, compounded for 30 years (which means that he should almost return 1.5 x his initial investment PLUS whatever profit he makes on your property).
That’s why real-estate is such a great long-term investment, and why the stock market is a terrible short-term gamble.
What advice would you give?
Great post with some really nice analysis. However, my best advice would be to buy a much cheaper car. Cars are one of the worst investments that can be made. But your analysis is spot on and applies to investing generally. Very nice post.
