Stocks Plummet as Brexit Looms

- By James Li

On June 23, the United Kingdom voted in a referendum in favor of leaving the European Union. Known as "Brexit," the U.K.'s secession from the EU tormented stock markets globally. Among the stocks that tumbled due to Brexit, global banks and airline companies suffered the most.

The vote heard 'round the world

Since 1973, Great Britain has been a member of the EU and its precursor, the European Economic Community (EEC). However, two years later, the first attempt to secede from the EEC failed, as the electorate voted 67.2% to 32.8% to stay in the EEC. After several failed attempts to earn parliamentary seats, one political party, the United Kingdom Independence Party (UKIP), finally earned a parliamentary seat. Additionally, Prime Minister David Cameron won the 2015 general election.


After winning the election, Cameron announced the referendum on the U.K.'s membership in the EU. Throughout the day, British citizens queued up in large swarms and voted on the referendum, which ultimately resulted in a 51.89% to 48.11% vote in favor of secession. While initial reports suggest that Britain will stay in the EU, the final votes proved otherwise. Immediately following the vote, the U.S. and U.K. stock markets faltered. The price of British pounds tumbled to a new low, and the Dow dropped nearly 500 points when the markets opened. Additionally, the Nasdaq gave up 3.65% while the Standard and Poor's 500 index declined nearly 3%. The U.S./U.K. exchange rate decreased likely due to the sharp decline in British pound prices.

Global banks and airline companies suffer huge drops in stock price

While the U.S. stock market tanked after the Brexit vote, banks and airline companies suffered the worst declines in stock prices. Among the "systematically important financial institutions" or SIFIs, Citigroup Inc. (NYSE:C) and Morgan Stanley (MS) lost over 9% of their stock prices. Other banks, like Bank of America Corp. (BAC), Goldman Sachs Group Inc. (GS) and JPMorgan Chase Co. (JPM), gave up over 6% of their stock prices.

These banks have modest financial strength: Their interest coverage and equity to asset ratios are very low compared to typical growing companies. The only bank to have a return on invested capital higher than its WACC, JPM has the highest interest coverage among the SIFIs. Additionally, JPM's interest coverage currently outperforms 74% of global banks. Despite having high interest coverage, JPM does not have the highest equity-to-asset (E/A) ratio. Currently, Citigroup has a slightly higher E/A ratio than Bank of America, which historically had the lowest leverage.

U.S. airline companies also tanked following Brexit. American Airlines Group Inc. (AAL) tumbled 10.35%, worse than Delta Air Lines Inc. (DAL) and United Continental Holdings Inc. (UAL), which declined 7.48% and 8.41%.

Among the top three U.S. airline companies, American Airlines has the worst equity-to-asset ratio, interest coverage and Altman Z-score. With an interest coverage of 6.95, lower than 54% of global airline companies, American Airlines barely meets Ben Graham's requirement of 5. While the top three airline companies all have Z-scores in distress zones, American's Z-score is the lowest at 1.29. Worse, American's equity-to-asset ratio currently underperforms 85% of global airline companies. These financial strength metrics suggest that American Airlines is most likely to go bankrupt throughout the Brexit process.

On the other hand, Delta has the strongest financial outlook among the top three U.S. airline companies. Currently, Delta's interest coverage of 17.38 outperforms 69% of global airlines companies, suggesting that the Skyteam airline can easily pay interest expenses. Delta also has the lowest Beneish M-score, suggesting that the company is the least likely to manipulate its earnings results. Additionally, among these three airline companies, Delta has the highest Piotroski F-score, a 7 out of 9. Although United has equity-to-asset ratios similar to Delta, United has lower interest coverage and a higher Beneish M-score. United is also the only airline company among these three that possibly manipulated its earnings.
