MarketWatch writes, "Once offering the worst return on Wall Street, cash is now looking like the best asset to own, says Morgan Stanley." The article says, "Stock sellers are picking up where they left off on Friday, as the market appears to be waking up from its August slumber with a vengeance.... That brings us to our call of the day from Morgan Stanley strategist Andrew Sheets who says investors should consider cash as a viable investment strategy, even if that hasn't seemed like such a winning proposal in the past. 'Holding cash ... was an explicitly defensive decision for much of the last 12 years. Of course it offered a worse return than anything else in the market,' Sheets told clients in the bank's Sunday note." "But the idea that holding cash means paying for insurance is no longer accurate," said Sheets, who notes that U.S. 6-month Treasury bills yields (3.1%) are the highest since late 2007, offering 157 basis points more than S&P 500 dividends, 21 basis points more than 10-year Treasurys, and just 60 basis points under the U.S. aggregate bond index AGG." "For USD investors, cash has ceased to be a material drag on a portfolio's current yield," he said. Even holding cash in Europe, which used to be extremely costly, is no longer, as German 6-month bill yields are positive for the first time since 2014." MarketWatch comments, "Streets said that on a cross-asset basis, U.S. dollar cash offers a high current yield, liquidity, and a better 12-month total return than Morgan Stanley's own implied forecasts for U.S. equity, U.S. Treasurys, investment grade and high yield credit -- 'with considerably less volatility.'" The brief adds, "This is why Morgan Stanley's core optimized fixed-income portfolios are overweight short-dated fixed income, he said. Against other currencies the dollar also holds up, and the bank's foreign exchange experts see more of that strength ahead, especially against the euro, which was once again tapping parity on Monday as worries over Europe winter fuel shortages build."
