Chris McGrath/Getty ImagesA stock market correction is likely in the coming weeks, says Fairlead Strategies' Katie Stockton.Technical indicators suggest a decline of nearly 10% for the S&P 500.Investors should use relief rallies to hedge and only hold stocks that are trading above key support levels, Stockton said.A correction in the stock market is looming in the early days of 2025, a note from Fairlead Strategies said this week.The technical-focused research firm led by Katie Stockton said in a Wednesday note that a continued sell-off in the S&P 500 is likely over the next few weeks.The index flashed new intermediate-term "sell" signals that were confirmed last week, creating a setup that "supports a correction over the coming weeks," Stockton said.Technical sell signals noted by Stockton include the MACD and daily stochastics, two momentum-based indicators, as well as a signal known as the DeMARK Indicator.The end of the seven-day Santa Claus trading window on Friday also bolsters the case for a continued decline.
