what causes a stock to go up or down
When information technology comes to the stock market place, one affair is for certain: stocks go up and stocks go downwardly. The question is: what makes a stock go up or down?
What makes a stock become up or down is determined by the contempo operating results of a business and its future expectations.
This means stock prices reverberate both fundamentals (operating results) and emotions (future expectations). When either one or both of these change for a particular stock, its cost volition be affected.
What Makes A Stock Become Upwards (Or Down)?
It'due south incommunicable to pinpoint exactly what makes a stock go upward or downward on a daily footing. To borrow a phrase from The Princess Bride, "Anyone who says differently is selling something."
On the other manus, it'south quite simple to encounter what makes a stock go upward or down over time. Stock prices are based on how investors call up a company will perform in the future compared to how the company is performing at present.
In any investment, investors are betting on the future. Because the future is uncertain, stocks cannot be priced based on a concern's current operating results alone. They must be valued by predicting future operation.
Price Ratios
In club to quantify these predictions, investors use toll ratios. Cost ratios are elementary tools which testify how a stock is priced compared to its contempo operating results.
For instance, a Price-to-Earnings (P/E) ratio of 10 says that a stock is valued 10 times higher than its current earnings.
This does not mean that investors expect the company's earning to increment past a multiple of x in the near hereafter. It merely means that if the earnings were to stay constant, investors would intermission even on their initial investment after 10 years. In other words, the earnings yield on the principal is ten% (10/100 = 0.1).
Say a stock has a P/E of fifty and investors still wait to receive an earnings yield of ten%. Paying fifty times earnings only makes sense if the company'due south earnings are expected to increment essentially over time.
Multiple Futures
No matter how badly stock analysts pretend to be fortune tellers, no one can accurately forecast a company's future performance (especially on a consistent basis).
Charles Duhigg, in his book Smarter, Faster, Better: The Secrets of Being Productive in Life and Business organization, summarizes the reality of what the future is. Duhigg says, "The hereafter isn't one thing. Rather, it is a multitude of possibilities that often contradict one another until one of them comes true."
These multitude of possibilities are what cause price ratios to fluctuate so often for whatever one stock.
Although there are endless numbers of possible futures when considering a stock investment, there are really only three general scenarios.
Scenario #1: A company'south operating results will increase.
Scenario #ii: A visitor's operating results volition remain constant.
Scenario #three: A company'due south operating results will decrease.
The level of a stock'south cost ratios is determined based on which scenario investors anticipate will come truthful for that particular stock.
Scenario #1: Loftier price ratios.
Scenario #2: Average price ratios.
Scenario #3: Low price ratios.
Operating Results
Before getting too focused on price ratios, it'due south of import to remember that change in operating results is the second half to determining what makes a stock become upward or downwards.
Say a stock is reporting earnings per share (EPS) of $five and has a P/E of x. The stock would be valued at $50 per share ($5 x 10 = $50). Then, the company unexpectedly reports EPS of $5.50. If the P/Due east stays at 10, the stock is at present valued at $55 per share.
To summarize, stock prices go up or down depending on changes in operating results and the levels of its cost ratios.
The interesting thing is that changes in operating results near oftentimes trigger changes in cost ratios.
Because the future is hard to predict, operating results oftentimes differ (sometimes greatly) from what investors expect them to be. When a surprise similar this happens, future expectations are reconsidered and price ratios are modified.
Bear on of Surprises
In David Dreman's book, Contrarian Investment Strategies: The Psychological Edge, he notes the touch on of such surprises. Here is Dreman discussing the market'south reaction to unexpected results:
Several researchers have found that when a company reports an earnings surprise (that is, a figure above or below the consensus of analysts' forecasts), prices motion up when the surprise is positive and down when it is negative."
It makes intuitive sense that stock price adjustments correlate with positive or negative surprises.
Not simply do the surprises reveal a change in operating results, only the alter in operating results bear on the hereafter expectations of the company.
This explains why value stocks (low price ratios) outperform growth stocks (high cost ratios) over time.
Value Goes Up, Growth Goes Downward
Low price ratios anticipate negative futures (decreased profits) and high price ratios anticipate positive futures (increased profits). Therefore, stocks with low price ratios take more upside potential. On the flip side, stocks with high price ratios have nowhere to go but down.
In Contrarian Investment Strategies, Dreman references several studies which show that positive surprises bear on value stocks profoundly but just minimally impact growth stocks. The studies similarly show that negative surprises affect growth stocks greatly but but minimally affect value stocks.
Here'southward Dreman explaining the touch that both positive and negative surprises have on growth stocks:
Growth Stocks: Positive Surprises
Since analysts and investors akin believe that they can estimate precisely which stocks volition exist the real winners in the years alee, a positive surprise does trivial more than confirm their expectations."
Growth Stocks: Negative Surprises
Investors await merely glowingly results for these stocks. After all, they confidently - overconfidently - believe that they can divine the future of a 'good' stock with precision. Those stocks are not supposed to disappoint. People pay top dollar for them for exactly this reason. So when a negative surprise arrives, the results are devastating."
And here's Dreman explaining the touch that both positive and negative surprises have on value stocks:
Value Stocks: Positive Surprises
Those stock moved into the lowest category precisely considering they were expected to proceed to be dullards. They are the dogs of the investment globe and investors believe they deserve minimal valuations. A positive earnings surprise for a stock in this group is an event. Investors sit up and accept detect. Maybe, they think, these stocks are not as bad as analysts and investors believed."
Value Stocks: Negative Surprises
Investors have low expectations for what they believe to exist lackluster or bad stocks, and when these stocks do disappoint, few eyebrows are raised. The bottom line is that a negative surprise is not much of an event."
Fundamentals Modify Expectations
These scenarios explain why value stocks have nowhere to get just up, and growth stocks can only become down.
If a value stock'due south fundamentals unexpectedly increment, not merely volition its operating results ameliorate, but investors' future expectations will exist raised as a consequence.
Contrarily, a growth stock'south fundamentals are already expected to increase. Any comeback in operating results is already priced into the stock.
Decreased operating results are already priced into value stocks but not growth stocks. Unexpected poor performances wreak havoc on growth stocks, but non value stocks.
Buy Value Stocks
Because human being emotion plays a critical role in what makes a stock go up or downward during the brusk term, investors are wise to invest where expectations are low and positive surprises are probable.
To paraphrase a line from The Wolf of Wall Street, "It doesn't matter if y'all're Warren Buffett or Jimmy Buffett, no one knows if a stock will get upwardly, down, or sideways."
We tin can know, however, which stocks are more likely to get up. Buying stocks with low price ratios is a time-tested approach to achieving superior investment returns.
