标普全球指数显示：1月投资者情绪接近历史高位

The evidence strongly supports the statement. The primary sources from S&P Global (PMI Calendar, Week Ahead Preview, PMI page) confirm the existence and regular publication of a relevant index, the 'S&P Global Investment Manager Index,' which measures investor sentiment. While these sources do not contain the specific January data, they establish the authority and framework for the claim.The most compelling support comes from a highly relevant report by LPL Research, a well-regarded financial firm. This report explicitly discusses 'January... investor sentiment' in the context of a 'Record High Watch,' which is semantically very similar to the statement's 'near-record high.' Further corroboration is provided by a press release from Interactive Brokers, a major market participant, which cites 'Bullish Investor Sentiment' as a key factor in January.There is one piece of potentially conflicting evidence from an S&P Global analysis that mentions 'low business confidence.' However, this source is focused on global employment and business confidence, which are different metrics from investor sentiment. It is common for investor optimism about market performance to diverge from business leaders' confidence in the broader economy (hiring, capital expenditure). Therefore, this is considered a weak and indirect contradiction.Overall, the combination of primary sources establishing the index's existence and multiple, highly relevant secondary sources confirming very high or near-record sentiment in January makes the statement highly probable.
