Haven't listened to it yet, but some important clarifications:
Q1: Over what timeframe? 5 years, 10, 30? Low returns over next 5-10 years? Whatever, personally I don't care as I'll still be accumulating then.
Q2: US or international, or mix?
Q3: since "everyone" is expecting lower returns isn't it already priced in?
Also confused how inflation can be 2% and bond returns 3%. So he's assuming only 1% real return? Or 5% nominal? Currently inflation is zero and bond funds already yield 2%+..
Q1: I don't remember McNabb's timeframe. Bogle's is over ten years, but he's predicting 4% from stocks less inflation, including PE contraction over those ten years. I expect McNabb just means going forward with no PE contraction and no margin compression.
Q2: Think he was talking US only at the time. He did talk about better opportunities internationally.
Q3: "TINA" - There is no alternative.
Inflation has been running around 1-2% for five or so years. This years numbers are lower. A bit of inflation is good.
When interests rates rise current bond prices will fall. Maybe he was mentally pricing that in? Don't know. I don't do bonds myself, apart from a few ibonds bought years ago at way better interest rates.
