Mexico was struck by a massive earthquake with a magnitude of 7.1, bringing chaos, as well as human and economic damage. Mexico saw its viewership increase as much as 155% this week, as the stock market fell abruptly in the aftermath of the quake. iShares MSCI Mexico Capped ETF (EWW A) has fallen around 3% since the quake struck on September 19, arresting a rally and trimming gains since the beginning of the year to 25%.

The September 19 quake came a week after a stronger one hit Southern Mexico, including the capital. The death toll rose to at least 331 and around 44 buildings collapsed. In addition, the earthquake left around 4.6 million homes without electricity. On the day of the quake, the stock market swiftly dropped before trading was halted.

Fortunately, the current earthquake was less devastating than the one that hit in 1985 on the same day. Back then, more buildings collapsed taking the lives of around 10,000 people. Improvements in building standards since then have spared Mexico another massive tragedy.

Earthquakes of over 7 in magnitude are widely believed to have the potential to cause significant damage. Following the September 19 earthquake, another 11 aftershocks were noted, including one measuring 4.9. A notable part of the damage occurred in the Roma and Condesa districts.

Mexico’s economy has advanced at a decent pace over the past year, rising 0.6% in the quarter ending June 31. In each of the two previous quarters, the GDP grew by 0.7%.

Aerospace & defense is among the most-loved sectors in the current bull market, as it chiefly benefits from an escalation of rhetoric between North Korea and the U.S., as well as increasing Russia tensions. The defense ETFs saw around 81% more traffic this week compared to last, as some major names hit record highs. iShares U.S. Aerospace & Defense ETF (ITA B) reached its zenith on September 22, but lost ground since then. (ITA B) remains up around 1% for the past five days and 27% since the beginning of the year.

Geopolitical tensions coupled with Donald Trump’s intention to increase the defense budget had a positive impact on the sector. Tensions about North Korea, as well as military exercises by Russia in Belarus raised global jitters and boosted the defense sector. It’s clear now that Europe is also expected to increase its defense budget over time, indicating that the industry’s long-term prospects are bright. Over the near term, however, defense stocks may be in overbought territory, and a correction would not come as a surprise. Defense stocks have bigger valuation multiples compared to the S&P 500, although their earnings are expected to grow at a higher pace going forward.

The mood among investors in the Russian stock market has been surprisingly good, despite the fact that two large banks requested bailout funds from the country’s central bank.

B&N Bank, the 12th largest lender in the country, recently asked the central bank for rescue funds three weeks after another financial institution, Otkritie, had to be bailed out as well. Despite the ominous signs, investors did not panic as many analysts and officials reassured that there was no risk of widespread contagion. They cited the banking sector’s overall strong capital position, with half of the assets held by state-owned institutions.

Russia’s stocks are extremely undervalued, at least according to Robert Shiller, renowned economics professor and Nobel laureate. Shiller’s preferred cyclically adjusted price-to-earnings (CAPE) ratio points out that Russia is the most undervalued market from 26 countries analyzed, while the U.S. is the most overvalued. The CAPE ratio compares the average earnings of companies over the past ten years to the current levels of the index.

Semiconductors are trending for the second week in a row – last week they came in second. The rally in the sector continued this week, with iShares PHLX Semiconductor ETF (SOXX B+) advancing 0.70%. Year-to-date, (SOXX B+) is up more than 27%.

Semiconductors are a hot sector, benefiting from strong demand for computing power. Small wonder why shareholders in NXP Semiconductors (NXPI) are refusing to tender their shares to Qualcomm (QCOM), putting the merger at risk of not completing. Qualcomm has extended a few times the deadline for the tender offer, but an insignificant amount of shareholders agreed to sell their stock. The fact that activist hedge fund Elliott Management is campaigning for NXP to get a higher price gives investors confidence Qualcomm will raise its proposal. Indeed, shares in NXP are currently trading $2.7 above Qualcomm’s bid of $110 per share.

Financial equities saw their viewership rise 57% this week, as Federal Reserve Chair Janet Yellen surprised markets by signaling that interest rates will continue to increase despite low inflation. As a result, Financial Select Sector SPDR Fund (XLF A) rallied more than 1% since her remarks were made on September 26.

The financial sector benefits from a rising interest rate environment as the banks are able to charge their customers higher rates on loans. Yellen made clear that the Fed will continue to raise interest rates because the low inflation will prove transitory; although, she admitted the bank could act more slowly.
