It is arguably one of the most significant enhancements in Ethernet's history.Ĩ02.1aq Shortest Path Bridging Design and Evolution explains both the "what" and the "why" of the technology standard being set today. It is fair to say that lately, that balancing act leads to more neutral conclusions than decisive ones in the many indicators we follow.Facilitates both the understanding and adoption of 802.1aq as a networking solutionĨ02.1aq Shortest Path Bridging (SPB) is a technology that greatly simplifies the creation and configuration of carrier, enterprise, and cloud computing networks?by using modern computing power to deprecate signaling, and to integrate multicast, multipath routing, and large-scale virtualization. Regardless of what we think, however, we are always balancing the opportunities for reward with those for major risk. And while we cannot point to a definitive historical signal generated by the Neutrals being near a 6-year high, we can add this to list of items to be aware of as the market’s emotions get sorted out. After all, the stock market is way up over this time, but that probably has more to do with the psychological impact of suppressed interest rates than a “normal” economic expansion. Our take is that over this period, the shock of the horrendous market conditions of late 2007-early 2009 have gradually given way to a sense of uncertainty. While this index is notoriously volatile in the short-term, as you can see above, the percent of Neutral opinions has been in a generally rising trend since the bull market began six years ago. Only one vote per member is accepted in each weekly voting period. The AAII Investor Sentiment Survey measures the percentage of individual investors who are bullish, bearish, and neutral on the stock market for the next six months individuals are polled from the ranks of the AAII membership on a weekly basis.
