Is President-Elect Trump Driving a New Bull Market?

Whether you voted for him or not, we are all benefiting from the new Trump Bull Market. Isn't it great?

Maybe not. How can we tell if this is really the beginning of a new bull market?

First of all, secular bull markets are rare. They are characterized by higher highs and higher lows. Since 1871, there have been only four secular bull markets, as seen in the chart below. The last bull market was from 1982 through 2000. The full cycle since 2009 isn't over yet—and the low of that year never came close to historic lows, so it wouldn't be considered a secular bull anyway.



Within a secular bull, there can be many pullbacks and rallies. For instance, the 1982-2000 bull market included the crash in 1987, the 1990 pullback and the 1994 pullback. Conversely, bear markets can have rallies that many refer to as bull markets. The rally from 2002 to 2007 is the perfect example of a bear market rally. It was a big rally, but still a rally within a bear.

So how do you know if a rising market is a new bull market, or if it is just a blow-off rally? There are five measures of value used by wise investors:

1. Price-Earnings Ratio (P/E Ratio)

Bottom line, corporate earnings are what investors pay for when they buy stock. How much are you willing to pay for $1 of earnings is the question. How much is justified? This is what the P/E ratio tells you. The higher the P/E, the more an investor is paying for $1 of earnings. Historically, the market's average P/E ratio has been around 15, according to data from Standard & Poor's.

Bull markets tend to start after a bear market that chased investors away. Investor sentiment is so bad that in order to entice investors back to the market, P/E ratios have to be extremely low. According to research by money management firm Comstock Partners, that would mean a P/E of around 8. Today's P/E for Standard & Poor's 500-stock index is about 26, more than three times higher than the typical new bull market level.
