Negative sentiment is useful for timing bottoms in bull markets, but in bear markets sentiment could stay neutral to negative for months, or even years, as the market just keeps grinding lower. Clearing rallies are of course always possible, and can be very sharp & violent.
At a broad level, the bear market will continue at least until the end of Fed tightening is in sight, and right now it isn't - just the other day Powell said outright that he's willing to take rates as high as needed, and keep hiking for however long it takes to kill inflation, even if it means crushing the markets. I'd buckle up and hold on for a wild summer.
