Financial stocks SunTrust Banks, Inc. and Fifth Third Bancorp reportedly traditionally struggle every year around Memorial Day.

Looking at S&P 500 Index stocks over the past 10 years -- and considering only stocks with at least eight years' worth of returns -- a handful of bank names made the list. STI and FITB have ended the week lower 80% of the time, averaging losses of 2.49% and 2.07%, respectively, per data from Schaeffer's Senior Quantitative Analyst Rocky White.

“SunTrust Banks shares shot higher to start 2019, but ultimately ran into a wall in the $66-$67 area. This region acted as a floor for STI for most of 2018, and is in the vicinity of the equity's 320-day moving average,” Schaeffer's Investment Research reported. SunTrust Banks (STI) closed Friday at $62.35.

“Fifth Third stock, meanwhile, started 2019 in similar fashion, and ran into its own technical wall in the $29 neighborhood. This area rejected FITB's advances back in March, and again in early May. It's also home to the equity's 320-day moving average,” Schaeffer's Investment Research

Fifth Third stock (FITB) closed Friday at $27.23.

Meanwhile, Reuters reported that cash is still king for investors heading into the summer slowdown.

Stashing cash started during the global rout across financial markets late last year as investors worried about a global economic recession. Increasing a cash buffer is typical during times of economic and geopolitical strife.

But data and interviews with global wealth managers show that hoarding has continued at unusually high levels even as global stocks have rallied this year amid conflicting signals after the central banks’ U-turns, mixed macroeconomic data and fresh tumult in Washington’s spat with China, Reuters explained.

However, many U.S. investors have still been lured by the outperformance of U.S. Treasury bonds compared with total returns in U.S. equities over the past six months.
