Barring a breathtaking plunge, the bull market in U.S. stocks on Aug. 22 will become the longest in history, and optimistic investors argue it has miles to go before it rests. – Sue Chang, MarketWatch

Depending on how you measure beginnings and endings, or what constitutes a bear market or the beginning of a bull market, makes the statement a bit subjective. However, there is little argument the current bull market has had an exceptionally long life-span.

But rather than a “siren’s song” luring investors into the market, maybe it should serve as a warning.

Record levels” of anything are records for a reason.

It should be remembered that when records are broken that was the point where previous limits were reached. Also, just as in horse racing, sprinting or car races, the difference between an old record and a new one are often measured in fractions of a second.

Therefore, when a “record level” is reached it is NOT THE BEGINNING, but rather an indication of the PEAK of a cycle. Records, while they are often broken, are often only breached by a small amount, rather than a great stretch. While the media has focused on record low unemployment, record stock market levels, and record confidence as signs of an ongoing economic recovery, history suggests caution. For investors, everything is always at its best at the end of a cycle rather than the beginning.

The chart below has been floating around the “web” in several forms as “evidence” that investors should just stay invested at all times and not worry about the downturns. When taken at “face value,” it certainly appears to be the case. (The chart is based up Shiller’s monthly data and is inflation-adjusted total returns.)
