The highest level of market efficiency is the strong-form market efficiency. In such a market, security prices fully reflect both public and private information. So by definition, a market that is strong-form efficient is also semi-strong and weak-form efficient. This implies that even insiders with material private information would not be able to earn abnormal returns, as the prices already fully reflect the implications of the insider information. However, this is not likely because given the prohibition on insider trading in most markets, it would be unrealistic to expect markets to reflect all private information. Evidence suggests that markets are not strong-form efficient.
Many years ago, I was exactly where you are today—a CFA Level I candidate juggling a demanding full-time career with the daunting CFA curriculum. Coming from a Computer Engineering background, finance was entirely new territory for me. And yes, it was tough!
I struggled with dense textbooks, late-night cramming, and the frustration of concepts that seemed impossible after a long workday. But after passing Level I (barely), I realized something had to change.
Studying Smarter, Not Harder
Using the Pareto Principle (80/20 rule), I distilled the vast CFA syllabus into essential, easy-to-understand nuggets. I leaned into visual summaries and bite-sized learning sessions that worked around my busy schedule. This smarter approach helped me clear Levels II and III on my first attempts with significantly less stress.
