While valuations for U.S. stocks appear extended on some measures, Morgan Stanley said brightening sentiment after a market-friendly outcome in the French election and low volatility suggest investors should be adding risk to portfolios.
According to the U.S. broker, option pricing shows the probability of a 15 percent rally on the S&P 500 from current levels is the lowest it has been in the last 12 years.
Morgan Stanley recommends investors take advantage of cheap options and buy calls on the S&P 500 to get in front of brightening sentiment while also limiting potential downside.
Globally, Japanese equities were the broker's most favored market while emerging markets were least favored.
