Category: Efficient Markets


Recently sharing and discussing on the economic growth and the debt market yield spread impact recalled me some blogwork I did in the past and its worth sharing,

The abstract was based on the evidence that yield spread can serve as a leading indicator of economic activity.It’s important to understand few basic concepts before moving forward:

YIELD SPREAD: The difference between yield of long-term debt and short-term debt instrument is known as yield spread. Higher the difference between instruments greater will be the yield spread.

How concerned should we be about the cyclical performance of fund managers or of our own portfolio? blog

Performance differences, relative to a market benchmark, don’t really matter over the long-term. Short-term (months or years) under-performance is a fact of life if you are trying to beat the market.
