Book Review: Flash Boys

Flash Boys pbk mech.inddMichael Lewis is one of the great non-fiction authors of our time. He brilliantly tells tales involving highly technical details in ways that are entertaining and engaging, and–like any great artist–he makes the feat look easy. Lewis uses the colorful character and language of his subjects and weaves their personal stories into the greater picture.

The topic of Flash Boys is high-frequency trading (HFT). High-frequency traders utilize the fastest hardware, software, and internet connections–all carefully located–to engage in arbitrage schemes that suck billions of dollars from investors by beating their trades to the exchanges and raising the prices. What is most disturbing is how so many of the exchanges, banks, and brokers enable it, profit from it, or are complicit in it.

Flash Boys follows the men who exposed this dark underworld of Wall Street and set out to create their own alternative stock exchange that would play by its own rules, rules that are fair to investors. It also follows two other stories connected the HFT movement. This is a great story told by a great storyteller, and it is essential reading for anyone who desires a better understanding of how the world works.

The Net Worth Mindset

I didn’t get into studying finance until I was in my 30s, but when I did I studied hard and tried to make myself an expert in it. I had to, because I had to teach it.

Predictably, when I learned to look at my own personal balance sheet, my personal financial life literally started to come into balance. Continue reading “The Net Worth Mindset”

My Year with a Cash Back Credit Card

Like many consumers, my wife and I have long been suspicious of credit card companies. We are generally cautious about debt, not wanting to add to our massive student loan obligations. Credit cards, of course, are among the worst kinds of debt: with high interest rates compounding at a rapid rate.

Up until the end of 2016, the only credit cards we ever had were from making a large retail purchase on credit. For example, I purchased my Macbook Pro with Apple Credit, which is really just a Barclay credit card. The first year has no interest, so I paid off the account in one year and paid no interest. I wanted to keep that line of credit open to build my credit rating, so I set up automatic bill-pay on a bill that is $15/month. I pay off the balance every month, and I don’t use that card for anything else. It has been great for building my credit at no cost. Otherwise, it not very useful and adds to my stress sometimes when I worry about forgetting to pay it.

blue-cash-everydayWhile teaching my high school personal finance class about credit cards and credit ratings, I decided to do an experiment and try using a cash back card. I compared some cards and decided to apply for the American Express Blue Cash Everyday rewards card. Credit Karma informed me that with my credit history, my application would have a good chance of being accepted, and it was. Continue reading “My Year with a Cash Back Credit Card”

Book Review: Business Adventures

Business AdventuresThis is a neat book of magazine-style business stories. There are 12 stories about 25-100 pages each. They don’t relate to each other at all, other than all being related to business, finance, and economics.

The stories are all interesting and well-written, so it is both entertaining and informative. This gave me some lesson ideas for my entrepreneurship class.

This is a great way to learn some new business content in a fun and engaging way.
