Investing Lessons that Have Stood the Test of Time – Part 3

Welcome to the third part of the series on timeless investing lessons!

As a brief recap: Late last week, investor Irving Kahn passed away at age 109. Kahn started working on Wall Street in 1928, and was a disciple of the father of value investor, Ben Graham. With more than eight decades of experience in the stock market, there may be a number of precious investing lessons from Kahn that have stood the test of time.

I shared the first and second lessons in here and here respectively. The following is the final lesson I’d like to share.

Lifelong learning

The late Kahn was a believer in the value of lifelong learning in investing. Journalist Jason Zweig described Kahn’s daily routine (at 107 years old) in this article:

“He still works five days a week, slacking off only on the occasional Friday. He reads voraciously, including at least two newspapers every day and numerous magazines and books, especially about science. His abiding goal, he told me, is “to know much more about the stock I’m buying than the man who’s selling does.””

Here at the Motley Fool, we are lifelong students of investing. At times, we may not be able to gather all the important information about a company at one go. However, through reading up on our favorite companies over time, the long term investor stands to gain from a judicious accumulation of knowledge.

I’ve shared in an earlier article how accumulated knowledge on diamond systems manufacturer Sarine Technologies Ltd (SGX: U77) may have brought long term profits to the private investor. In this case, Sarine Technologies had increased the percentage of its recurring revenue from less than 10% in 2009 to 30% in 2013. This development could have set the stage for a 2,590% return since the start of 2009.

In all, if the late Kahn is able continue learning well past his 100 years, then I reckon that we should all consider being voracious learners given our much younger ages. I hope you enjoyed the series. Keep learning, Fools!
