Technical indicators also raised some concerns after last week’s market action. In his daily market commentary to clients, long-time analyst Dennis Gartman noted that the NYSE Composite index and the ratio of advancing stocks to decliners at the Big Board last week reversed recent upward trends, alongside a medium-term proprietary indicator from Lowry’s Reports, which pointed to a sell-off in the next few months. “Historically I’ve learnt that we need to watch these numbers, because not paying attention could be costly,” Mr Gartman said.
