Whenever a stock price drops after a great earnings report, there is always a sense of confusion among traders. If you take a look at social stock trading websites such as StockTwits, you will see questions such as “Why is it dropping when the ER beat?” or “Why isn’t it going up?”
A recent example is Facebook’s Q3 2017 earnings report. It crushed all expectations, yet the stock price dropped afterwards. Traders were quick to register their disappointment, as many of them expected the price to “pop”.
Well, the stock price did pop, for a little while, in the after hours market, before falling back down to earth again:
Why does this happen?
Buy the rumor, sell the news.
Sometimes, the price of a good earnings report is already priced into the market. For instance, in the days leading up to Facebook’s Q3 2017 report, many analysts were expecting the company to “crush expectations”. As a result, investors bought in and the price continued to rise. Expectations were high, to say the least. However, once the news broke and these expectations became a reality, many people decided to cash in on their profits. This is sometimes referred to as “buy the rumor, sell the news.” i.e. Buy because you reckon it’s going to beat and then sell as soon as it does – thereby locking in your profits.
Sell before other traders sell.
Because “profit taking” is so prevalent after a good earnings report, many traders feel as though they need to sell before other traders begin to sell. If I think that other traders are going to lock in their profits and drive the price down, I am more likely to sell myself. Then, if it does drop, I can simply buy it back on the dip. If it doesn’t drop, who cares? I made my profit and I can simply move onto the next stock.
The volume after a company reports earnings often provides large hedge funds with the opportunity to exit a large position without knocking down the price of the stock. If the ER is a beat, then there will be plenty of buyers to prop up the price and help them unwind their position.
As traders take their profits and the stock price declines, a sense of panic begins to set in. This leads to further selling and a steeper decline in the price of the stock. Remember: The market isn’t always rational as traders will often make decisions based on their emotions. The long term fundamentals of a company might not matter to somebody that is watching their profits evaporating by the minute.
If you take the factors above into account, you can easily see why a stock can plummet after an earnings beat. Fortunately, if the fundamentals of the company are strong and there isn’t any cause for concern, the price will often bounce back after a couple of days / weeks.
