Thanks Phil another great week of guiding us!

Phil - It is nice being more discipline with my trading. Generally, I am out earlier than most, but my results, overall, are much better than they were when I was trying to squeeze 80 cups of lemonade out of one lemon! On the other side, I am learning the value of rolling and turning losses into non-losses or small gains. I so appreciate the time you have spent with me and others who have benefited greatly from your knowledge. Thank you!

"The notion of market efficiency is not a well-posed and empirically refutable hypothesis. To make it operational, one must specify additional structure, e.g., investors’ preferences, information structure, etc. But then a test of market efficiency becomes a test of several auxiliary hypotheses as well, and a rejection of such a joint hypothesis tells us little about which aspect of the joint hypothesis is inconsistent with the data."

One of the reasons for this state of affairs is the fact that the EMH, by itself, is not a well-defined and empirically refutable hypothesis. To make it operational, one must specify additional structure, e.g. investors' preferences, information structure. But then a test of the EMH becomes a test of several auxiliary hypotheses as well, and a rejection of such a joint hypothesis tells us little about which aspect of the joint hypothesis is inconsistent with the data. Are stock prices too volatile because markets are inefficient, or is it due to risk aversion, or dividend smoothing? All three inferences are consistent with the data. Moreover, new statistical tests designed to distinguish among them will no doubt require auxiliary hypotheses of their own which, in turn, may be questioned."

Efficient Market Hypothesis - Morningstar

Thanks for the USO mention, Phil, 140% on my USO lottery ticket in 12 hours, and no hesitation in taking the money and running — you have trained us well. Sometimes it's teaching, but with this kind of stuff, where you get whipped like a dog if you let 250% profit melt away, it's definitely training. Happy Fourth!!!

The Efficient Market Hypothesis - CFA Level 1 | Investo…

I have followed along with your commentary and alerts and have been flabbergasted at your quick analytical skills and your journalistic skills to explain it clearly. In a little over three weeks I have cleared almost 1000.00 dollars and got an intensive education at the same time. I would like to immediately upgrade my membership.

CFA Level 1 - The Efficient Market Hypothesis

Fed days are fun! Just for grins I decided to see how much money I could make in two clicks. I bought DIA calls right when the surge started and then sold them the minute they hit my account. Net gain of 20% in 20 seconds. Can't do that very often…

Learn the basics of the efficient market hypothesis

Phil/thankyou. Phil, I went over the recording of last weeks webinar. I liked it a lot and wanted to thank you. I thought the case studies (company reviews) were detailed, I learned more about selling puts process and also what happens if stock continues to go down after that, I liked the fact that we discuss so many different avenues like stocks, optiond, futures, oil, commodities etc… I replayed portions of it multiple times to make sure I was grasping it but wanted to say good job. Thanks…

Efficient Market Hypothesis: Is The Stock Market Efficient?

GOOG, NFLX and AAPL all bought last hour Friday. Sold into the excitement the first hour today for an average of 15% on the options. And lots of them. Thanks again Phil for teaching me so well.
