The S&P 500 index on Friday finished above a chart level that delivered a dose of encouragement to stock-market bulls arguing that the U.S. bear-market bottom is in, though technical analysts warned that it might not be a signal to go all in on equities. The S&P 500
on Friday rose 1.7% to close at 4,280.15. The finish above 4,231 would mean the large-cap benchmark has recovered — or retraced — more than 50% of its fall from a Jan. 3 record finish at 4796.56.
“Since 1950 there has never been a bear market rally that exceeded the 50% retracement and then gone on to make new cycle lows,” said Jonathan Krinsky, chief market technician at BTIG, in a note earlier this month.
Stocks rose across the board Friday, with the S&P 500 booking a fourth straight weekly gain. The Dow Jones Industrial Average
advanced more than 420 points, or 1.3%, on Friday and the Nasdaq Composite
rose 2.1%. The S&P 500 attempted to complete the retracement in Thursday’s session, when it traded as high as 4,257.91, but gave up gains to end at 4,207.27. Krinsky, in a Thursday update, had noted that an intraday breach of the level doesn’t cut it, but had cautioned that a close above 4,231 would still leave him cautious about the near-term outlook. “Because the retracement is based on a closing basis, we would want to see a close above 4,231 to trigger that signal. Whether or not that happens, however, the tactical risk/reward looks poor to us here,” he wrote. What’s so special about a 50% retracement? Many technical analysts pay attention to what’s known as the Fibonacci ratio, attributed to a 13th century Italian mathematician known as Leonardo “Fibonacci” of Pisa. It’s based on a sequence of whole numbers in which the sum of two adjacent numbers equals the next highest number (0,1,1,2,3,5,8,13, 21 …). If a number in the sequence is divided by the next number, for example 8 divided by 13, the result is near 0.618, a ratio that’s been dubbed the Golden Mean due to its prevalence in nature in everything from seashells to ocean waves to proportions of the human body. Back on Wall Street, technical analysts see key retracement targets for a rally from a significant low to a significant peak at 38.2%, 50% and 61.8%, while retracements of 23.6% and 76.4% are seen as secondary targets. The push above the 50% retracement level during Thursday’s recession may have contributed to a round of selling itself, said Jeff deGraaf, founder of Renaissance Macro Research, in a Friday note.
