The Globe and Mail reports in its Wednesday, Sept. 30, edition that it is a nerve-racking time in the stock market. The Globe's Tim Shufelt writes that bonds are showing stress signals, and higher borrowing costs weigh heavily on a debt-laden world. The oil shock in the Middle East is reigniting inflation, while fears of superintelligent machines loom. And these gas prices are hard to believe! Mr. Shufelt say it is hard to shake the feeling that something is about to break. Bearish commentary suggests that a golden age for investors may be ending. Notably, U.S. investor Michael Burry, known for betting against Wall Street before the financial crisis, has moved up his timeline for the artificial intelligence crash. What's not being talked about much any more are the excellent reasons to stay invested. Stock valuations have been dropping for the past year, for example, and not just by a little bit -- hardly what you would expect to see in the middle of a speculative frenzy. Goldman Sachs analysts say, "Technology equities have not experienced a classic bubble because valuation levels are much lower than in previous financial bubbles." Plus, corporate earnings are booming globally. And balance sheets are generally healthy.
