I just started listening to this about a month ago. Some are not specifically about investing.
I really enjoyed the one this past week where Sam Stovall discusses current stock valuations in the United States. He compares some current metrics to past history. I had never heard of the 'Rule of 20' for determining stock market valuations. (Market PE + inflation = 20 means fair value). Sam does think there is more room for higher returns in the Emerging Markets and International, but seemed reasonably optimistic about U.S. prospects as well.
