Top 6 Investment Innovations in Recent Decades

These are my top picks for innovations that most benefit personal investors.

#6:  Decimal pricing.    Do you remember when stocks were priced in fractions?  Like 23 and 3/8?  This was not cool.  Not only was it clunky, but it meant that bid/ask spreads were usually stuck at 1/8 of a dollar per share, or 12.5 cents per share.  Luckily, today most investments are priced in decimals.  Some exceptions include bonds and the interest rates on most mortgages.  How archaic!

#5: Free online investment info.   Information used to largely come in paper form, and cost money.  Or you could pay tons of money for Quotron… really not practical.

#4: Discount online brokers.   My Dad used to pay $50-$100 per stock trade — over the phone with a broker.  Today some of my ETF trades are free, many of my trades average about $1, and my most expensive trades cost $8.

#3: Exchange-Traded Funds (ETFs).  ETFs fix most of the problems with mutual funds such as high(er) expenses and lack of intra-day trading.  ETFs also open up a wide variety of investment options including access to commodities, leveraged funds, and precious metals.

#2: Index investing.  Index investing brings two huge advantages.  First, incredibly low costs.  Second, maximum diversification.  Index investing has, and continues to revolutionize the investing playing field.

#1: 401(k)s (and IRAs).   Named after a once-obscure IRS code, 401(k)s, or 401Ks, offer investors decades of tax-deferred growth opportunity.  IRAs offer a similar advantage.  Finally Roth IRAs offer similar tax-deferral opportunities where the tax benefit is back-loaded.
