Any election campaign requires a great deal of energy and stamina. However, if a contender is almost 70, a presidential race can exhaust them physically and mentally. No wonder any evidence of a candidate’s health problems trigger game-changing speculations on the election outcome.

Nowadays, investors are reviewing their portfolios, monitoring news on Hillary Clinton’s health. The former secretary of state left abruptly the ceremony of the 15th anniversary of the September 11 attacks in New York. She nearly collapsed in public and was helped into a van by aides. Someone from the audience using a cellphone camera filmed the incident and posted the video in the Internet. This instantly caused fierce discussions about the state of Mrs. Clinton’s health. Experts warn financial markets to brace for a lot of volatility in case her health changes for the worse. “If we found out that there was something catastrophic about her health it obviously would matter, but you have to be very careful about extrapolating shorter-term news,” Jonathan Golub, managing director and chief US market strategist at RBC Capital Markets LLC in New York, made a comment. “What we do know is we have two candidates around 70 years old and in reality it must be brutal running around the world for two years.”

Financial markets have been far too complacent about the likelihood of Hillary Clinton’s victory on Election Day. So investors have to reassess risks in the run-up to the pending presidential elections on November 8.
